Chapter 2 Host Management with the VMware Host Client
Managing Hardware for an ESXi Host by Using the VMware Host Client
When you log in to an ESXi host by using the VMware Host Client, you can manage PCI devices and
congure power management seings.
Host Power Management Policies
You can apply several power management features in ESXi that the host hardware provides to adjust the
balance between performance and power. You can control how ESXi uses these features by selecting a power
management policy.
Selecting a high-performance policy provides more absolute performance, but at lower eciency and
performance per wa. Low-power policies provide less absolute performance, but at higher eciency.
ESXi provides ve power management policies. If the host does not support power management, or if the
BIOS seings specify that the host operating system is not allowed to manage power, only the Not
Supported policy is available.
You can select a policy for the host that you manage by using the VMware Host Client. If you do not select a
policy, ESXi uses Balanced by default.
Table 2‑1. CPU Power Management Policies
Power Management PolicyDescription
High PerformanceDo not use any power management features.
Balanced (Default)Reduce energy consumption with minimal performance
compromise
Low PowerReduce energy consumption at the risk of lower
performance
CustomUser-dened power management policy. Advanced
conguration becomes available.
When a CPU runs at lower frequency, it can also run at lower voltage, which saves power. This type of
power management is typically called Dynamic Voltage and Frequency Scaling (DVFS). ESXi aempts to
adjust CPU frequencies so that virtual machine performance is not aected.
When a CPU is idle, ESXi can apply deep halt states, also known as C-states. The deeper the C-state, the less
power the CPU uses, but it also takes longer for the CPU to start running again. When a CPU becomes idle,
ESXi applies an algorithm to predict the idle state duration and chooses an appropriate C-state to enter. In
power management policies that do not use deep C-states, ESXi uses only the shallowest halt state for idle
CPUs, C1.
Change Power Management Policies in the VMware Host Client
Change the power management policies of the host that you are managing to control the energy
consumption of your host.
Procedure
1Click Manage in the VMware Host Client inventory and click Hardware.
2Click Power Management and click Change policy.
The available power management policies are displayed.
3Select the radio buon next to the policy that you want to apply.
4Click OK.

vSphere Single Host Management - VMware Host Client
Licensing for ESXi Hosts
ESXi hosts are licensed with vSphere licenses. Each vSphere license has a certain CPU capacity that you can
use to license multiple physical CPUs on ESXi hosts. When you assign a vSphere license to a host, the
amount of CPU capacity that is consumed is equal to the number of physical CPUs in the host. vSphere
Desktop that is intended for VDI environments is licensed on per virtual machine basis.
To license an ESXi host, you must assign it a vSphere license that meets the following prerequisites:
The license must have sucient CPU capacity to license all physical CPUs on the host. For example, to
n
license two ESXi hosts that have four CPUs each, you need to assign a vSphere license with a minimum
capacity of 8 CPUs to the hosts.
The license must support all the features that the host uses. For example, if the host is associated with a
n
vSphere Distributed Switch, the license that you assign must support the vSphere Distributed Switch
feature.
If you aempt to assign a license that has insucient capacity or does not support the features that the host
uses, the license assignment fails.
You can assign and reassign the CPU capacity of a vSphere license to any combination of ESXi hosts. . You
can assign a vSphere license for 10 CPUs to any of the following combinations of hosts:
Five 2-CPU hosts
n
Three 2-CPU hosts and one 4-CPU host
n
Two 4-CPU hosts and one 2-CPU host
n
One 8-CPU host and one 2-CPU host
n
Dual-core and quad-core CPUs, such as Intel CPUs that combine two or four independent CPUs on a single
chip, count as one CPU.
Evaluation Mode
When you install ESXi, its default license is evaluation mode. Evaluation mode licenses expire after 60 days.
An evaluation mode license provides the set of features that equals the highest vSphere product edition.
If you assign a license to an ESXi host before its evaluation period expires, the time available in the
evaluation period is decreased by the time already used. To explore the entire set of features that are
available for the host, you can set it back to evaluation mode, and use it for the remaining evaluation period.
For example, if you use an ESXi host in evaluation mode for 20 days and then assign a vSphere Standard
license to the host and then set the host back to evaluation mode, you can explore the entire set of features
that are available for the host for the remaining evaluation period of 40 days.
License and Evaluation Period Expiry
For ESXi hosts, license or evaluation period expiry leads to disconnection from vCenter Server. All powered
on virtual machines continue to work, but you cannot power on virtual machines after they are powered o.
You cannot change the current conguration of the features that are in use. You cannot use the features that
remained unused while the host was in evaluation mode.
Licensing ESXi Hosts After Upgrade
If you upgrade an ESXi host to a version that starts with the same number, you do not need to replace the
existing license with a new one. For example, if you upgrade a host from ESXi 5.1 to 5.5, you can use the
same license for the host.
14 VMware, Inc.
Chapter 2 Host Management with the VMware Host Client
If you upgrade an ESXi host to a version that starts with a dierent number, you must apply a new license.
For example, if you upgrade an ESXi host from 5.x to 6.x, you need to license the host with a vSphere 6
license.
vSphere Desktop
vSphere Desktop is intended for VDI environments such as Horizon View. The license usage for vSphere
Desktop equals the total number of powered on desktop virtual machines running on the hosts that are
assigned a vSphere Desktop license.

2Click Assign license, enter a license key in the form XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, and click Check
license.
3Click Assign license to save your changes.
Remove a License from an ESXi Host in the VMware Host Client
To remain in compliance with the licensing models of products that you use with vSphere, you must remove
all unassigned licenses from the inventory. If you have divided, combined, or upgraded licenses in My
VMware, you must remove the old licenses.
For example, suppose that you have upgraded a vSphere license from 5.5 to 6.0 in My VMware. You assign
the license to ESXi 6.0 hosts. After assigning the new vSphere 6.0 licenses, you must remove the old vSphere
5.5 license from the inventory.
Procedure
1Click Manage in the VMware Host Client inventory and click Licensing.
2Right-click a license from the list, click Remove license, and click Remove.
Update Your VMware Host Client Environment to the Latest Version
To evaluate whether you are using the latest version of the VMware Host Client, check what VIBs are
installed to your environment and examine the VIBs version information. You can update your
VMware Host Client environment by entering a URL to a VIB or an ESX update metadata.ziple.
If you provide a VIB, an existing VIB that is installed to your VMware Host Client environment is updated
to the new VIB.
VMware, Inc. 15
vSphere Single Host Management - VMware Host Client
If a link to a metadata.ziple is provided, the entire ESXi system is updated to the version described by the
metadata.zip le.
C If the host is managed by vSphere Update Manager, updating the host via this message might
cause Update Manager to report the host as non-compliant.

Managing Security and Users for an ESXi Host by Using the
VMware Host Client
The ESXi hypervisor architecture has many built-in security features that you can congure to enhance
security. By using the VMware Host Client, you can congure features, such as active directory, and you can
also manage certicates.
Managing Host Authentication by Using the VMware Host Client
When you log in to an ESXi host by using the VMware Host Client, you can check whether active directory
and smart card authentication are enabled, and you can also join the host to a directory service domain.
Join an ESXi Host to a Directory Service Domain by Using the VMware Host Client
To use a directory service for your host, you must join the host to the directory service domain.
You can enter the domain name in one of two ways:
name.tld (for example, domain.com): The account is created under the default container.
n
16 VMware, Inc.
Chapter 2 Host Management with the VMware Host Client
name.tld/container/path (for example, domain.com/OU1/OU2): The account is created under a particular
n
organizational unit (OU).
To use the vSphere Authentication Proxy service, see vSphere Security.
Procedure
1Click Manage in the VMware Host Client inventory and click Security & Users.
2Click Authentication and click Join domain.
3Enter a domain name.
Use the form name.tld or name.tld/container/path.
4Enter the user name and password of a directory service user account that has permissions to join the
host to the domain and click Join domain.
5(Optional) If you intend to use an authentication proxy, enter the proxy server IP address and click Join
domain.
Using Active Directory to Manage ESXi Users
You can congure ESXi to use a directory service such as Active Directory to manage users.
Creating local user accounts on each host presents challenges with having to synchronize account names
and passwords across multiple hosts. Join ESXi hosts to an Active Directory domain to eliminate the need to
create and maintain local user accounts. Using Active Directory for user authentication simplies the ESXi
host conguration and reduces the risk for conguration issues that could lead to unauthorized access.
When you use Active Directory, users supply their Active Directory credentials and the domain name of the
Active Directory server when adding a host to a domain.
Using vSphere Authentication Proxy
When you use the vSphere Authentication Proxy, you do not need to transmit Active Directory credentials
to the host . Users supply the domain name of the Active Directory server and the IP address of the
authentication proxy server when they add a host to a domain.
vSphere Authentication Proxy is especially useful when used with Auto Deploy. You can set up a reference
host that points to Authentication Proxy and set up a rule that applies the reference host's prole to any
ESXi host provisioned with Auto Deploy. Even if you use vSphere Authentication Proxy in an environment
that uses certicates that are provisioned by VMCA or third-party certicates, the process works seamlessly
as long as you follow the instructions for using custom certicates with Auto Deploy. See the vSphereSecurity guide.
N You cannot use vSphere Authentication Proxy in an environment that supports only IPv6.
Managing Host Certificates by Using the VMware Host Client
When you log in to an ESXi host by using the VMware Host Client, you can view the certicate details of
your host, such as the issuer and the validity period, and you can also import new certicates
View Certificate Details for an ESXi Host in the VMware Host Client
For ESXi 6.0 and later, hosts that are in VMCA mode or custom mode, you can view certicate details when
you are logged in to the host with the VMware Host Client. The certicate information can be useful for
debugging.

4Paste a PEM formaedcerticate in the certicate text box and click Import.
You do not have to import the certicate immediately but you cannot reboot the host between
generating the certicate signing request and importing the certicate.
Managing Users with the VMware Host Client
Manage users to control who is authorized to log in to ESXi.
Users and roles control who has access to the ESXi host components and what actions each user can
perform.
In vSphere 5.1 and later, ESXi user management has the following caveats .
The users created when you connect directly to an ESXi host are not the same as the vCenter Server
n
users. When the host is managed by vCenter Server, vCenter Server ignores users created directly on
the host.
You cannot create ESXi users by using the vSphere Web Client. You must log in to the host directly with
n
the VMware Host Client to create ESXi users .
ESXi 5.1 and later does not support local groups. However, Active Directory groups are supported.
n
To prevent anonymous users, such as root, from accessing the host with the Direct Console User Interface
(DCUI) or ESXi Shell, remove the user's administrator privileges on the root folder of the host. This applies
to both local users and Active Directory users and groups.
Add an ESXi User in the VMware Host Client
Adding a user to the users table updates the internal user list that the host maintains.
Prerequisites
Review the password requirements in the vSphere Security documentation.

vSphere Single Host Management - VMware Host Client
Managing ESXi Roles in the VMware Host Client
ESXi grants access to objects only to users who are assigned permissions for the object. When you assign a
user permissions for the object, you do so by pairing the user with a role. A role is a predened set of
privileges.
ESXi hosts provide three default roles, and you cannot change the privileges associated with these roles.
Each subsequent default role includes the privileges of the previous role. For example, the Administrator
role inherits the privileges of the Read Only role. Roles that you create do not inherit privileges from any of
the default roles.
You can create custom roles by using the role-editing dunctions in the VMware Host Client to create
privilege sets that match your user needs. Also, the roles you create directly on a host are not accessible in
vCenter Server. You can work with these roles only if you log in to the host directly from the
VMware Host Client.
N When you add a custom role and do not assign any privileges to it, the role is created as a read-only
role with the System.Anonymous, System.View, and System.Readsystem-dened privilege.
If you manage an ESXi host through vCenter Server, maintaining custom roles in the host and
vCenter Server can result in confusion and misuse. In this type of conguration, maintain custom roles only
in vCenter Server.
You can create host roles and set permissions through a direct connection to the ESXi host with the
VMware Host Client.
Add a Role in the VMware Host Client
You can create roles to suit the access control needs of your environment.
Prerequisites

Place a Host in Maintenance Mode in the VMware Host Client
You place a host in maintenance mode when you need to service it, for example, to install more memory. A
host enters or leaves maintenance mode only as the result of a user request.
The host is in a state of Entering Maintenance Mode until all running virtual machines are powered o or
migrated to dierent hosts. You cannot power o virtual machines or migrate virtual machines to a host that
is entering or in maintenance mode.
To place a host in maintenance mode, all virtual machines that are running on the host must be powered o
or migrated to dierent hosts. If you aempt to place a host that has running virtual machines on it in
maintenance mode, DRS must power o or migrate the running virtual machines for the task to complete. If
a time out occurs before the virtual machines are powered o or migrated, an error message appears.
When all virtual machines on the host are inactive, the host's icon displays under maintenance and the
host's Summary panel indicates the new state. While in maintenance mode, the host does not allow you to
deploy or power on a virtual machine.
Prerequisites
Before you place a host in maintenance mode, power o all virtual machines that are running on that host or
migrate them to another host either manually or automatically by DRS.
Procedure
Right-click the host and select Enter maintenance mode.
u
The host is in maintenance mode until you select Exit maintenance mode.
Managing Permissions in the VMware Host Client
For ESXi, permissions are dened as access roles that consist of the roles assigned to a user for dierent
objects such as a virtual machine or ESXi host. Permissions grant users the right to perform the activities
specied by the role on the object to which the role is assigned.
For example, to congure memory for the host, a user must be granted a role that includes the
Host..Memory privilege. By assigning dierent roles to users for dierent
objects, you can control the tasks that users can perform by using the VMware Host Client.
When connecting directly to a host with the VMware Host Client, the root and vpxuser user accounts have
the same access rights as any user assigned the Administrator role on all objects.
All other users initially have no permissions on any object, which means the users cannot view or perform
tasks on these objects. A user with Administrator privileges must assign permissions to these users to allow
them to perform tasks.
Many tasks require permissions on more than one object. The following rules can help you determine which
roles to assign to users to allow particular tasks:
Any task that consumes hard disk space, such as creating a virtual disk or taking a snapshot, requires
n
the Datastore.Allocate Space privilege on the target datastore and the privilege to perform the
operation itself.
Each host and cluster has its own implicit resource pool that contains all the resources of that host or
n
cluster. Deploying a virtual machine directly to a host or cluster requires the Resource.Assign Virtual
Machine to Resource Pool privilege.
The list of privileges is the same for both ESXi and vCenter Server.
You can create roles and set permissions through a direct connection to the ESXi host.
24 VMware, Inc.
Chapter 2 Host Management with the VMware Host Client
Permission Validation
vCenter Server and ESXi hosts that use Active Directory regularly validate users and groups against the
Windows Active Directory domain. Validation occurs whenever the host system starts and at regular
intervals specied in the vCenter Server seings.
For example, if user Smith was assigned permissions and in the domain the user’s name was changed to
Smith2, the host concludes that Smith no longer exists and removes permissions for that user when the next
validation occurs.
Similarly, if user Smith is removed from the domain, all permissions are removed when the next validation
occurs. If a new user Smith is added to the domain before the next validation occurs, the new user Smith
receives all the permissions the old user Smith was assigned.
Assign Permissions to a User for an ESXi Host in the VMware Host Client

Lockdown Mode
To increase the security of your ESXi hosts, you can put them in lockdown mode. In lockdown mode,
operations must be performed through vCenter Server by default.
Normal Lockdown Mode and Strict Lockdown Mode
With vSphere 6.0, you can select normal lockdown mode or strict lockdown mode.
Normal Lockdown Mode
In normal lockdown mode, the DCUI service remains active. If the
connection to the vCenter Server system is lost, and access through the
vSphere Web Client is unavailable, privileged accounts can log in to the ESXi
host's Direct Console Interface and exit lockdown mode. Only the following
accounts can access the Direct Console User Interface:
Accounts in the Exception User list for lockdown mode who have
n
administrative privileges on the host. The Exception Users list is meant
for service accounts that perform specic tasks. Adding ESXi
administrators to this list defeats the purpose of lockdown mode.
28 VMware, Inc.
Chapter 2 Host Management with the VMware Host Client
Users dened in the DCUI.Access advanced option for the host. This
n
option is for emergency access to the Direct Console Interface in case the
connection to vCenter Server is lost. These users do not require
administrative privileges on the host.
Strict Lockdown Mode
In strict lockdown mode, which is new in vSphere 6.0, the DCUI service is
stopped. If the connection to vCenter Server is lost and the
vSphere Web Client is no longer available, the ESXi host becomes
unavailable, unless the ESXi Shell and SSH services are enabled and
Exception Users are dened. If you cannot restore the connection to the
vCenter Server system, you must reinstall the host.
Lockdown Mode and the ESXi Shell and SSH Services
Strict lockdown mode stops the DCUI service. However, the ESXi Shell and SSH services are independent of
lockdown mode. For lockdown mode to be an eective security measure, ensure that ESXi Shell and SSH
services are also disabled. These services are disabled by default.
When a host is in lockdown mode, users on the Exception Users list can access the host from the ESXi Shell
and through SSH if they have the Administrator role on the host. This access is possible even in strict
lockdown mode. Leaving the ESXi Shell service and the SSH service disabled is the most secure option.
N The Exception Users list is meant for service accounts that perform specic tasks such as host
backups, and not for administrators. Adding administrator users to the Exception Users list defeats the
purpose of lockdown mode.
Put an ESXi Host in Normal Lockdown Mode by Using the VMware Host Client
You can use the VMware Host Client to enter normal lockdown mode.
Procedure
1Right-click Host in the VMware Host Client inventory, select Lockdown mode from the drop-down

Specify Lockdown Mode Exception Users in the VMware Host Client
Starting with vSphere 6.0, you can add users to the exception users list by using the VMware Host Client.
These users do not lose their permissions when the host enters lockdown mode. You can add service
accounts, such as a backup agent to the exception users list.
Exception users are host local users or Active Directory users with privileges dened locally for the ESXi
host. They are not members of an Active Directory group and are not vCenter Server users. These users are
allowed to perform operations on the host based on their privileges. That means, for example, that a readonly user cannot disable lockdown mode on a host.
N The exception users list is useful for service accounts that perform specic tasks, such as host
backups, and not for administrators. Adding administrator users to the exception users list defeats the
purpose of lockdown mode.
Procedure
1Click Manage in the VMware Host Client inventory and click Security & Users.

Creating a Virtual Machine in the VMware Host Client
Virtual machines are the key component in a virtual infrastructure. You can create virtual machines to add
to the host inventory.
When you create a virtual machine, you associate it with a particular datastore and select an operating
system and virtual hardware options . After you power on the virtual machine, it consumes resources
dynamically as the workload increases, or returns resources dynamically as the workload decreases.
Every virtual machine has virtual devices that provide the same function as physical hardware. A virtual
machine gets CPU and memory, access to storage, and network connectivity from the host it runs on.

feature, you must comply with the requirements of the guest operating
system EULA.
You can add, change, or congure virtual machine memory resources or
options to enhance virtual machine performance. You can set most of the
memory parameters during virtual machine creation or after the guest
operating system is installed. The memory resource seings for a virtual
machine determine how much of the host's memory is allocated to the
virtual machine. The virtual hardware memory size determines how much
memory is available to applications that run in the virtual machine.
You can add large-capacity virtual disks to virtual machines and add more
space to existing disks, even when the virtual machine is running. You can
set most of the virtual disk parameters during virtual machine creation or
after you install the guest operating system.
Storage controllers appear to a virtual machine as dierent types of SCSI
controllers, including BusLogic Parallel, LSI Logic Parallel, LSI Logic SAS,
and VMware Paravirtual SCSI. You can set the type of SCSI bus sharing for
a virtual machine and indicate whether the SCSI bus is shared. Depending
on the type of sharing, virtual machines can access the same virtual disk
simultaneously on the same server or on any server. You can change the
SCSI controller conguration for a virtual machine on an ESXi host only.
If a virtual machine has multiple hard disks or CD/DVD-ROM devices,
you can add up to three additional SATA controllers to assign the devices
to. When you spread the devices among several controllers, you can
improve performance and avoid data trac congestion. You can also add
additional controllers if you exceed the thirty-device limit for a single
controller. You can boot virtual machines from SATA controllers and use
them for large-capacity virtual hard disks.

OVF and OVA Limitations for the VMware Host Client
You can create a virtual machine in the VMware Host Client by using OVF and VMDK les, or OVA les.
However, several limitations are applicable to this deployment method .
OVA Limitations
You can upload OVA les by using either a Web browser or a client. The memory requirements are
signicant and might cause the Web browser to stop responding or make the system unstable. The size of
the OVA le that can be uploaded depends on how much memory is available on your system. VMware
tests show that Google Chrome can upload OVA les of about 1 gigabyte. Mozilla Firefox can extract larger
OVA les, but might become unresponsive.
To deploy a large OVA le, VMware recommends to rst extract the OVA on your system by running the
command tar -xvf <file.ova>. Then you can provide the deployment wizard with the OVF and VMDKs as
separate les.
OVF Limitations
The size of OVF les that a Web browser can upload are also limited. Dierent Web browsers have dierent
le size limits. Recent versions of Internet Explorer can upload OVF les up to 4 gigabytes in size. MozillaFirefox also has a 4 gigabyte limit. Google Chrome can handle larger les and there is no documented limit.
Deploy a Virtual Machine from an OVF or OVA File in the VMware Host Client
Use the New Virtual Machine wizard to deploy virtual machines from OVF and VMDK les, or from OVA

Introduction to VMware Tools
VMware Tools is a suite of utilities that you install in the operating system of a virtual machine.
VMware Tools enhances the performance of a virtual machine and makes possible many of the ease-of-use
features in VMware products. For example, the following features are just some of the features that are
available only if VMware Tools is installed:
Signicantly faster graphics performance and Windows Aero on operating systems that support Aero
n
The Unity feature, which enables an application in a virtual machine to appear on the host desktop like
n
any other application window
Shared folders between host and guest le systems
n
Copying and pasting text, graphics, and les between the virtual machine and the host or client desktop
n
Improved mouse performance
n
Synchronization of the clock in the virtual machine with the clock on the host or client desktop
n
Scripting that helps automate guest operating system operations
n
Runs pre-freeze and post-thaw quiescing scripts
n
Enables capturing quiesced snapshots of guest operating systems
n
Periodically collects and sends network, disk, and memory usage information from guest operating
n
systems to ESXi hosts.
Sends heartbeat information to each virtual machine every second and collects guest heartbeat
n
information from guest operating systems. VMware HA uses the heartbeat information to determine
virtual machine availability.
Transports the OVF environment to guest operating systems using the guest OS environment variable
n
guestinfo.ovfEnv that contains the XML document.
Enables guest customization for virtual machines.
n
VMware, Inc. 43
vSphere Single Host Management - VMware Host Client
Although the guest operating system can run without VMware Tools, many VMware features are not
available until you install VMware Tools. For example, if you do not have VMware Tools installed in your
virtual machine, you cannot get heartbeat information from guest operating systems or cannot use the
shutdown or restart options from the toolbar. You can only use the power options and you have to shut
down your guest operating systems from each virtual machine console. You cannot use VMware Tools for
connecting and disconnecting virtual devices, and shrinking virtual disks.
The installation procedure varies, depending on the operating system. For information about installing or
upgrading VMware Tools on your guest operating systems, see the Upgrading Virtual Machines chapter. For
instructions about installing VMware Tools, see the VMware Knowledge base article at
hp://kb.vmware.com/kb/1014294.
VMware highly recomments that you always run the latest version of VMware Tools. You can congure
your virtual machine to automatically check for and apply VMware Tools upgrades each time you power on
your virtual machines. For information about enabling automatic upgrade of VMware Tools on your virtual
machines, see vSphere Virtual Machine Administration.
Installing VMware Tools
Although you can use guest operating systems without VMware Tools, many VMware features are not
available unless you install VMware Tools. VMware Tools enhances the performance of the guest operating
system of your virtual machines.
Installing VMware Tools is part of the process of creating new virtual machines. It is important to upgrade
VMware Tools as updates become available. For information about creating virtual machines, see the VirtualMachine Administration Guide.
The installers for VMware Tools are ISO image les. An ISO image le looks like a CD-ROM to your guest
operating system. Each type of guest operating system, including Windows, Linux, Solaris, FreeBSD, and
NetWare, has an ISO image le. When you install or upgrade VMware Tools, the rst virtual CD-ROM disk
drive of the virtual machine temporarily connects to the VMware Tools ISO le of your guest operating
system.
For information about installing or upgrading VMware Tools in Windows virtual machines, Linux virtual
machines, Mac OS X virtual machines, Solaris virtual machines, NetWare virtual machines, or FreeBSD
virtual machines, see Virtual Machine Administration Guide.
Install VMware Tools from the VMware Host Client
VMware Tools is a suite of utilities that you install in the operating system of a virtual machine. VMware
Tools enhances the performance and management of the virtual machine.
You can install VMware Tools in one or more virtual machines by using the VMware Host Client.
Procedure
1Click Virtual Machines in the VMware Host Client inventory.
2Select a virtual machine from the list.
The virtual machine must be powered on to install VMware Tools.
3Click Actions, select Guest OS from the drop-down menu, and select Install VMware Tools.
Upgrading VMware Tools
You can upgrade VMware Tools manually, or you can congure virtual machines to check for and install
newer versions of VMware Tools.
The guest operating system checks the version of VMware Tools when you power on a virtual machine. The
status bar of your virtual machine displays a message when a new version is available.
44 VMware, Inc.
Chapter 3 Virtual Machine Management with the VMware Host Client
In Windows virtual machines, you can set VMware Tools to notify you when an upgrade is available. If this
notication option is enabled, the VMware Tools icon in the Windows taskbar includes a yellow caution icon
when a VMware Tools upgrade is available.
To install a VMware Tools upgrade, you can use the same procedure that you used for installing VMware
Tools the rst time. Upgrading VMware Tools means installing a new version.
For Windows and Linux guest operating systems, you can congure the virtual machine to automatically
upgrade VMware Tools. Although the version check is performed when you power on the virtual machine,
on Windows guest operating systems, the automatic upgrade occurs when you power o or restart the
virtual machine. The status bar displays the message Installing VMware Tools ... when an upgrade is in
progress.
I After you upgrade VMware Tools on Linux guest operating systems, new network modules
are available but are not used until you either restart the guest operating system or stop networking, unload
and reload the VMware networking kernel modules, and restart networking. This behavior means that even
if VMware Tools is set to automatically upgrade, you must restart or reload network modules to make new
features available.
This strategy avoids network interruptions and allows you to install VMware Tools over SSH.
Upgrading VMware Tools on Windows guest operation systems automatically installs the WDDM graphics
drivers. The WDDM graphics driver makes the sleep mode available in guest OS power seings to adjust
the sleep options. For example, you can use the sleep mode seingChange when the computer sleeps to
congure your guest OS to automatically go to sleep mode after a certain time or prevent your guest OS
from automatically switching to sleep mode after being idle for some time.
For vSphere virtual machines, you can use one of the following processes to upgrade multiple virtual
machines at the same time.
You can use one of the following processes to upgrade multiple virtual machines at the same time.
Log in to vCenter Server, select a host or cluster, and on the Virtual Machines tab specify the virtual
n
machines on which to perform a VMware Tools upgrade.
Use Update Manager to perform an orchestrated upgrade of virtual machines at the folder or
n
datacenter level.
Some features in a particular release of a VMware product might depend on installing or upgrading to the
version of VMware Tools included in that release. Upgrading to the latest version of VMware Tools is not
always necessary, however, VMware highly recommends that you upgrade to the most updated version of
the VMware Tools. Newer versions of VMware Tools are compatible with several ESXi host versions. To
avoid unnecessary upgrades, evaluate whether the added features and capabilities are necessary for your
environment. See vSphere Virtual Machine Administration. However, VMware highly recommends installing
and using the latest version of VMware Tools.

Virtual CPU Configuration
You can add, change, or congure CPU resources to improve virtual machine performance. You can set most
of the CPU parameters when you create virtual machines or after the guest operating system is installed.
Some actions require that you power o the virtual machine before you change the seings.
VMware uses the following terminology. Understanding these terms can help you plan your strategy for
CPU resource allocation.
CPU
CPU Socket
Core
Corelet
Thread
Resource sharing
The CPU or processor is the component of a computer system that performs
the tasks required for computer programs to run, and is the primary element
that performs the computer functions. CPUs contain cores.
A CPU socket is a physical connector on a computer motherboard that
connects to a single physical CPU. Some motherboards have multiple sockets
and can connect multiple multicore processors (CPUs).
A core contains a unit containing an L1 cache and functional units needed to
run programs. Cores can independently run programs or threads. One or
more cores can exist on a single CPU.
An AMD processor corelet is architecturally equivalent to a logical processor.
Certain future AMD processors contain a number of compute units, each of
which has a number of corelets. Unlike a traditional processor core, a corelet
lacks a complete set of private, dedicated execution resources and shares
some execution resources with other corelets such as an L1 instruction cache
or a oating-point execution unit. AMD refers to corelets as cores, but
because these are unlike traditional cores, are referred to as corelets in
VMware documentation to make resource sharing more apparent.
Some cores can run independent streams of instructions simultaneously. In
existing implementations, cores can run one or two software threads at one
time by multiplexing the functional units of the core between the software
threads, as necessary. Such cores are called dual or multithreaded.
Shares specify the relative priority or importance of a virtual machine or
resource pool. If a virtual machine has twice as many shares of a resource as
another virtual machine, it is entitled to consume twice as much of that
resource when the two virtual machines are competing for resources.
50 VMware, Inc.
Chapter 3 Virtual Machine Management with the VMware Host Client
Resource allocation
You can change CPU resource allocation seings, such as shares, reservation,
and limit, when available resource capacity does not meet demands. For
example, if at year end, the workload on accounting increases, you can
increase the accounting resource pool reserve.
vSphere Virtual
Symmetric
Virtual SMP or vSphere Virtual Symmetric Multiprocessingis a feature that
enables a single virtual machine to have multiple processors.
Multiprocessing (Virtual
SMP)
Virtual CPU Limitations
The maximum number of virtual CPUs that you can assign to a virtual machine depends on the hardware
version number of the virtual machine, the number of logical CPUs on the host, and the type of guest
operating system that is installed on the virtual machine.
Be aware of the following limitations:
A virtual machine cannot have more virtual CPUs than the number of logical cores on the host. The
n
number of logical cores is equal to the number of physical cores if hyperthreading is disabled. The
number of logical cores is equal to twice the number of physical cores if hyperthreading is enabled.
Not every guest operating system supports Virtual SMP, and guest operating systems that support this
n
function might support fewer processors than are available on the host. For information about Virtual
SMP support, see the VMware Compatibility Guide at hp://www.vmware.com/resources/compatibility.
Hyperthreaded hosts might aect virtual machine performance, depending on the workload. The best
n
practice is to test your workload to determine whether to enable or disable hyperthreading on your
hosts.
Configuring Multicore Virtual CPUs
VMware multicore virtual CPU support lets you control the number of cores per virtual socket in a virtual
machine. This capability lets operating systems with socket restrictions use more of the host CPU's cores,
which increases overall performance.
I When you congure your virtual machine for multicore virtual CPU seings, you must ensure
that your conguration complies with the requirements of the guest operating system EULA.
Using multicore virtual CPUs can be useful when you run operating systems or applications that can take
advantage of only a limited number of CPU sockets.
You can congure a virtual machine that runs on an ESXi host 6.0 and later to have up to 128 virtual CPUs.
A virtual machine cannot have more virtual CPUs than the actual number of logical CPUs on the host. The
number of logical CPUs means the number of physical processor cores or two times that number if
hyperthreading is enabled. For example, if a host has 128 logical CPUs, you can congure the virtual
machine for 128 virtual CPUs.
You congure how the virtual CPUs are assigned in terms of cores and cores per socket. Determine how
many CPU cores you want in the virtual machine, then select the number of cores you want in each socket,
depending on whether you want a single core CPU, dual-core CPU, tri-core CPU, and so on. Your selection
determines the number of sockets that the virtual machine has.
For more information about multicore CPUs, see the vSphere Resource Management documentation.

Change the Number of Virtual CPUs in the VMware Host Client
You can change the number of virtual CPUs while your virtual machine is powered o. If virtual CPU
hotplug is enabled, you can increase the number of virtual CPUs while the virtual machine is running.
Virtual CPU hot add is supported for virtual machines with multicore CPU support and ESXi 5.0 and later
compatibility. When the virtual machine is turned on and CPU hot add is enabled, you can hot add virtual
CPUs to running virtual machines. The number of CPUs that you add must be a multiple of the number of
cores that exist on each socket.
I When you congure your virtual machine for multicore virtual CPU seings, you must ensure
that your conguration complies with the requirements of the guest operating system EULA.

Virtual Memory Configuration
You can add, change, or congure virtual machine memory resources or options to enhance virtual machine
performance. You can set most of the memory parameters during virtual machine creation or after the guest
operating system is installed. Some actions require that you power o the virtual machine before changing
the seings.
The memory resource seings for a virtual machine determine how much of the host's memory is allocated
to the virtual machine. The virtual hardware memory size determines how much memory is available to
applications that run in the virtual machine. A virtual machine cannot benet from more memory resources
than its congured virtual hardware memory size. ESXi hosts limit the memory resource use to the
maximum amount useful for the virtual machine, so that you can accept the default of Unlimited memory
resources.
Change the Memory Configuration of a Virtual Machine in the VMware Host Client
You can recongure the amount of memory allocated to a virtual machine to enhance performance.
Minimum memory size is 4MB for virtual machines that use BIOS rmware. Virtual machines that use EFI
rmware require at least 96MB of RAM or they cannot power on.
Maximum memory size for a virtual machine depends on the host's physical memory and the virtual
machine's compatibility seing.
If the virtual machine memory is greater than the host memory size, swapping occurs, which can have a
severe eect on virtual machine performance. The maximum for best performance represents the threshold
above which the host’s physical memory is insucient to run the virtual machine at full speed. This value
uctuates as conditions on the host change, for example, as virtual machines are powered on or o.
The memory size must be a multiple of 4MB.

Allocate Memory Resources to a Virtual Machine in the VMware Host Client
You can change the amount of memory resources allocated to a virtual machine by using the shares,
reservations, and limits seings. The host determines the appropriate amount of physical RAM to allocate to
virtual machines based on these seings. You can assign a high or low shares value to a virtual machine,
depending on its load and status.
The following user-denedseingsaect the memory resource allocation of a virtual machine.
Limit
Places a limit on the consumption of memory for a virtual machine. This
value is expressed in megabytes.
Reservation
Species the guaranteed minimum allocation for a virtual machine. The
reservation is expressed in megabytes. If the reservation cannot be met, the
virtual machine will not turn on.
Shares
Each virtual machine is granted a number of memory shares. The more
shares a virtual machine has, the greater share of host memory it receives.
Shares represent a relative metric for allocating memory capacity. For more
information about share values, see the vSphere Resource Management
documentation.
You cannot assign a reservation to a virtual machine that is larger than the virtual machine's congured

Network Virtual Machine Configuration
ESXi networking features enable communication between virtual machines on the same host, between
virtual machines on dierent hosts, and between other virtual and physical machines.
The networking features also allow management of ESXi hosts and enable communication between
VMkernel services, such as NFS, iSCSI, or vSphere vMotion, and the physical network. When you congure
networking for a virtual machine, you select or change an adapter type, a network connection, and whether
to connect the network when the virtual machine powers on.
Network Adapter Types
When you congure a virtual machine, you can add network adapters (NICs) and specify the adapter type.
The type of network adapters that are available depend on the following factors:
The virtual machine compatibility, which depends on the host that created or most recently updated it.
n

VMXNET
VMXNET 2 (Enhanced)
Emulated version of the Intel 82574 Gigabit Ethernet NIC. E1000E is the

Emulated version of the Intel 82545EM Gigabit Ethernet NIC, with drivers
available in most newer guest operating systems, including Windows XP and
later and Linux versions 2.4.19 and later.
Identies itself as a Vlance adapter when a virtual machine boots, but
initializes itself and functions as either a Vlance or a VMXNET adapter,
depending on which driver initializes it. With VMware Tools installed, the
VMXNET driver changes the Vlance adapter to the higher performance
VMXNET adapter.
Emulated version of the AMD 79C970 PCnet32 LANCE NIC, an older 10
Mbps NIC with drivers available in 32-bit legacy guest operating systems. A
virtual machine congured with this network adapter can use its network
immediately.
Optimized for performance in a virtual machine and has no physical
counterpart. Because operating system vendors do not provide built-in
drivers for this card, you must install VMware Tools to have a driver for the
VMXNET network adapter available.
Based on the VMXNET adapter but provides high-performance features
commonly used on modern networks, such as jumbo frames and hardware
ooads. VMXNET 2 (Enhanced) is available only for some guest operating
systems on ESX/ESXi 3.5 and later.
VMXNET 3
A paravirtualized NIC designed for performance. VMXNET 3 oers all the
features available in VMXNET 2 and adds several new features, such as
multiqueue support (also known as Receive Side Scaling in Windows), IPv6
ooads, and MSI/MSI-X interrupt delivery. VMXNET 3 is not related to
VMXNET or VMXNET 2.
SR-IOV passthrough
Representation of a virtual function (VF) on a physical NIC with SR-IOV
support. The virtual machine and the physical adapter exchange data
without using the VMkernel as an intermediary. This adapter type is suitable
for virtual machines where latency might cause failure or that require more
CPU resources.
SR-IOV passthrough is available in ESXi 5.5 and later for guest operating
systems Red Hat Enterprise Linux 6 and later, and Windows Server 2008 R2
with SP2. An operating system release might contain a default VF driver for
certain NICs, while for others you must download and install it from a
location provided by the vendor of the NIC or of the host.
For information about assigning an SR-IOV passthrough network adapter to
a virtual machine, see the vSphere Networking documentation.

Network Adapters and Legacy Virtual Machines
Legacy virtual machines are virtual machines that are supported by the product in use, but are not current
for that product. The default network adapter types for all legacy virtual machines depend on the adapters
available and compatible to the guest operating system and the version of virtual hardware on which the
virtual machine was created.
If you do not upgrade a virtual machine to correspond with an upgrade to a newer version of an ESXi host,
your adapter seings remain unchanged. If you upgrade your virtual machine to take advantage of newer
virtual hardware, your default adapter seings will likely change to be compatible with the guest operating
system and upgraded host hardware.
To verify the network adapters that are available to your supported guest operating system for a particular
version of vSphere ESXi, see the VMware Compatibility Guide at

Virtual Disk Configuration
You can add large-capacity virtual disks to virtual machines and add more space to existing disks, even
when the virtual machine is running. You can set most of the virtual disk parameters during virtual machine
creation or after you install the guest operating system.
You can store virtual machine data in a new virtual disk, an existing virtual disk, or a mapped SAN LUN. A
virtual disk, which appears as a single hard disk to the guest operating system, is composed of one or more
les on the host le system. You can copy or move virtual disks on the same hosts or between hosts.
For virtual machines running on an ESXi host, you can store the virtual machine data directly on a SAN
LUN instead of storing it in a virtual disk le. This ability is useful if you are running applications in your
virtual machines that must detect the physical characteristics of the storage device. Additionally, mapping a
SAN LUN allows you to use existing SAN commands to manage storage for the disk.
To accelerate virtual machine performance, you can congure virtual machines to use vSphere Flash Read
Cache™. For details about Flash Read Cache behavior, see the vSphere Storage documentation.
When you map a LUN to a VMFS volume, vCenter Server or the ESXi host creates a raw device mapping
(RDM) le that points to the raw LUN. Encapsulating disk information in a le allows vCenter Server or the
ESXi host to lock the LUN so that only one virtual machine can write to it. This le has a .vmdk extension,
but the le contains only disk information that describes the mapping to the LUN on the ESXi system. The
actual data is stored on the LUN. You cannot deploy a virtual machine from a template and store its data on
a LUN. You can store only its data in a virtual disk le.
The amount of free space in the datastore is always changing. Ensure that you leave sucient space for
virtual machine creation and other virtual machine operations, such as growth of sparse les, snapshots,
and so on. To review space utilization for the datastore by le type, see the vSphere Monitoring andPerformance documentation.
Thin provisioning lets you create sparse les with blocks that are allocated upon rst access, which allows
the datastore to be over-provisioned. The sparse les can continue growing and ll the datastore. If the
datastore runs out of disk space while the virtual machine is running, it can cause the virtual machine to
stop functioning.
About Virtual Disk Provisioning Policies
When you perform certain virtual machine management operations, such as creating a virtual disk, cloning
a virtual machine to a template, or migrating a virtual machine, you can specify a provisioning policy for the
virtual disk le.
NFS datastores with Hardware Acceleration and VMFS datastores support the following disk provisioning
policies. On NFS datastores that do not support Hardware Acceleration, only thin format is available.

Thick Provision Lazy
Zeroed
Thick Provision Eager
Zeroed
Thin Provision
Creates a virtual disk in a default thick format. Space required for the virtual
disk is allocated when the disk is created. Data remaining on the physical
device is not erased during creation, but is zeroed out on demand at a later
time on rst write from the virtual machine. Virtual machines do not read
stale data from the physical device.
A type of thick virtual disk that supports clustering features such as Fault
Tolerance. Space required for the virtual disk is allocated at creation time. In
contrast to the thick provision lazy zeroed format, the data remaining on the
physical device is zeroed out when the virtual disk is created. It might take
longer to create virtual disks in this format than to create other types of
disks.
Use this format to save storage space. For the thin disk, you provision as
much datastore space as the disk would require based on the value that you
enter for the virtual disk size. However, the thin disk starts small and at rst,
uses only as much datastore space as the disk needs for its initial operations.
If the thin disk needs more space later, it can grow to its maximum capacity
and occupy the entire datastore space provisioned to it.
Thin provisioning is the fastest method to create a virtual disk because it
creates a disk with just the header information. It does not allocate or zero
out storage blocks. Storage blocks are allocated and zeroed out when they
are rst accessed.
N If a virtual disk supports clustering solutions such as Fault Tolerance,
do not make the disk thin.

Use Disk Shares to Prioritize Virtual Machines in the VMware Host Client
You can change the disk resources for a virtual machine. If multiple virtual machines access the same VMFS
datastore and the same logical unit number (LUN), use disk shares to prioritize the level of access that
virtual machines have to resources. Disk shares distinguish high-priority from low-priority virtual
machines.
You can allocate the I/O bandwidth of the host to the virtual hard disks of a virtual machine. You cannot
pool disk I/O across a cluster.
The shares value represents the relative metric for controlling disk bandwidth to all virtual machines.
Disk shares are relevant only within a given host. The shares assigned to virtual machines on one host have
no eect on virtual machines on other hosts.
You can select an IOP limit, which sets an upper limit for storage resources that are allocated to a virtual
machine. IOPs are the number of I/O operations per second.

Virtual Machine Controller Configuration in the VMware Host Client
In the VMware Host Client, you can add various controllers to virtual machines, such as USB controllers,
SCSI controllers, Paravirtual SCSI controllers, and SATA controllers. You can also change the SCSI Bus
sharing conguration and the SCSI controller type.
Add a USB Controller to a Virtual Machine in the VMware Host Client
USB controllers can be added to virtual machines to support USB passthrough from an ESXi host or from a
client computer to a virtual machine.
You can add one virtual xHCI controller, one virtual EHCI controller, and one virtual UHCI controller per
virtual machine. With Hardware Version 11, the supported number of root hub ports per xHCI controller is
eight (four logical USB 3.0 ports and four logical USB 2.0 ports).
The conditions for adding a controller vary, depending on the device version, the type of passthrough (host
or client computer), and the guest operating system.

keyboard access.
For virtual machines with Linux guests, you can add one or both controllers, but 3.0 superspeed devices are
not supported for passthrough from an ESXi host to a virtual machine. You cannot add two controllers of
the same type.
For USB passthrough from an ESXi host to a virtual machine, the USB arbitrator can monitor a maximum of
15 USB controllers. If your system includes controllers that exceed the 15 controller limit and you connect
USB devices to them, the devices are not available to the virtual machine.

About VMware Paravirtual SCSI Controllers
VMware Paravirtual SCSI controllers are high performance storage controllers that can result in greater
throughput and lower CPU use. These controllers are best suited for high performance storage
environments.
VMware Paravirtual SCSI controllers are available for virtual machines with ESXi 4.x and later compatibility.
Disks on such controllers might not experience optimal performance gains if they have snapshots or if
memory on the ESXi host is over commied. This behavior does not mitigate the overall performance gain
of using VMware Paravirtual SCSI controllers as compared to other SCSI controller options.
If you have virtual machines with VMware Paravirtual SCSI controllers, those virtual machines cannot be
part of an MSCS cluster.
For platform support for VMware Paravirtual SCSI controllers, see the VMware Compatibility Guide at
hp://www.vmware.com/resources/compatibility.

Add a SATA Controller to a Virtual Machine in the VMware Host Client
If a virtual machine has multiple hard disks or CD/DVD-ROM devices, you can add up to three additional
SATA controllers to assign the devices to. When you assign the devices to dierent controllers, you can
improve performance and avoid data trac congestion. You can also add controllers if you need to exceed
the thirty-device limit for a single controller.
You can boot virtual machines from SATA controllers and use them for large-capacity virtual hard disks.
Not all guest operating systems support AHCI SATA controllers. Typically, when you create virtual
machines with ESXi 5.5 and later compatibility and Mac OS X guest operating systems, a SATA controller is
added by default for the virtual hard disk and CD/DVD-ROM devices. Most guest operating systems,
including Windows Vista and later, have a default SATA controller for CD/DVD-ROM devices. For

Using Snapshots To Manage Virtual Machines
Snapshots preserve the state and data of a virtual machine at the time you take the snapshot. When you take
a snapshot of a virtual machine, the virtual machine is not aected and only an image of the virtual machine
in a given state is copied and stored. Snapshots are useful when you must revert repeatedly to the same
virtual machine state, but you do not want to create multiple virtual machines.
You can take multiple snapshots of a virtual machine to create restoration positions in a linear process. With
multiple snapshots, you can save many positions to be able to perform many types of work processes.
Snapshots operate on individual virtual machines. Taking snapshots of multiple virtual machines, for
example, taking snapshots for all members of a team, requires that you take a separate snapshot of each
team member's virtual machine.
Snapshots are useful as a short term solution for testing software with unknown or potentially harmful
eects. For example, you can use a snapshot as a restoration point during a linear or iterative process, such
as installing update packages, or during a branching process, such as installing dierent versions of a
program. Using snapshots ensures that each installation begins from an identical baseline.
With snapshots, you can preserve a baseline before making changes to a virtual machine in the snapshot
tree.
Several operations for creating and managing virtual machine snapshots and snapshot trees are available in
the Snapshot Manager of the VMware Host Client. These operations enable you to create snapshots, restore
any snapshot in the snapshot hierarchy, delete snapshots, and more. You can create extensive snapshot trees
that you can use to save the state of a virtual machine at any specic time and restore the virtual machine
state later. Each branch in a snapshot tree can have up to 32 snapshots.
72 VMware, Inc.
Chapter 3 Virtual Machine Management with the VMware Host Client
A snapshot preserves the following information:
Virtual machine seings. The virtual machine directory, which includes the disks added or changed
n
after you take the snapshot.
Power state. The virtual machine can be powered on, powered o, or suspended.
n
Disk state. State of all the virtual machine's virtual disks.
n
(Optional) Memory state. The contents of the virtual machine's memory.
n
The Snapshot Hierarchy
The Snapshot Manager presents the snapshot hierarchy as a tree with one or more branches. Snapshots in
the hierarchy have parent to child relationships. In linear processes, each snapshot has one parent snapshot
and one child snapshot, except for the last snapshot, which has no child snapshot. Each parent snapshot can
have more than one child. You can revert to the current parent snapshot or restore any parent or child
snapshot in the snapshot tree and create more snapshots from that snapshot. Each time you restore a
snapshot and take another snapshot, a branch, or child snapshot, is created.
Parent Snapshots
The rst virtual machine snapshot that you create is the base parent
snapshot. The parent snapshot is the most recently saved version of the
current state of the virtual machine. Taking a snapshot creates a delta disk
le for each disk aached to the virtual machine and optionally, a memory
le. The delta disk les and memory le are stored with the base .vmdkle.
The parent snapshot is always the snapshot that appears immediately above
the You are here icon in the Snapshot Manager. If you revert or restore a
snapshot, that snapshot becomes the parent of the You are here current state.
N The parent snapshot is not always the snapshot that you took most
recently.
Child Snapshots
A snapshot of a virtual machine taken after the parent snapshot. Each child
snapshot contains delta les for each aached virtual disk, and optionally a
memory le that points from the present state of the virtual disk (You are
here). Each child snapshot's delta les merge with each previous child
snapshot until reaching the parent disks. A child disk can later be a parent
disk for future child disks.
The relationship of parent and child snapshots can change if you have multiple branches in the snapshot
tree. A parent snapshot can have more than one child. Many snapshots have no children.
I Do not manually manipulate individual child disks or any of the snapshot congurationles
because doing so can compromise the snapshot tree and result in data loss. This restriction includes disk
resizing and making modications to the base parent disk by using vmkfstools.
Snapshot Behavior
Taking a snapshot preserves the disk state at a specic time by creating a series of delta disks for each
aached virtual disk or virtual RDM and optionally preserves the memory and power state by creating a
memory le. Taking a snapshot creates a snapshot object in the Snapshot Manager that represents the virtual
machine state and seings.
VMware, Inc. 73
vSphere Single Host Management - VMware Host Client
Each snapshot creates an additional delta .vmdk disk le. When you take a snapshot, the snapshot
mechanism prevents the guest operating system from writing to the base .vmdkle and instead directs all
writes to the delta disk le. The delta disk represents the dierence between the current state of the virtual
disk and the state that existed at the time that you took the previous snapshot. If more than one snapshot
exists, delta disks can represent the dierence between each snapshot. Delta disk les can expand quickly
and become as large as the entire virtual disk if the guest operating system writes to every block of the
virtual disk.
Snapshot Files
When you take a snapshot, you capture the state of the virtual machine seings and the virtual disk. If you
are taking a memory snapshot, you also capture the memory state of the virtual machine. These states are
saved to les that reside with the virtual machine's base les.
Snapshot Files
A snapshot consists of les that are stored on a supported storage device. A Take Snapshot operation
creates .vmdk, -delta.vmdk, .vmsd, and .vmsn les. By default, the rst and all delta disks are stored with the
base .vmdkle. The .vmsd and .vmsnles are stored in the virtual machine directory.
Delta disk files
Flat file
Database file
A .vmdkle to which the guest operating system can write. The delta disk
represents the dierence between the current state of the virtual disk and the
state that existed at the time that the previous snapshot was taken. When you
take a snapshot, the state of the virtual disk is preserved, which prevents the
guest operating system from writing to it, and a delta or child disk is created.
A delta disk has two les, including a descriptor le that is small and
contains information about the virtual disk, such as geometry and childparent relationship information, and a corresponding le that contains the
raw data.
The les that make up the delta disk are referred to as child disks or redo
logs. A child disk is a sparse disk. Sparse disks use the copy-on-write
mechanism, in which the virtual disk contains no data in places, until copied
there by a write operation. This optimization saves storage space. A grain is
the unit of measure in which the sparse disk uses the copy-on-write
mechanism. Each grain is a block of sectors that contain virtual disk data.
The default size is 128 sectors or 64KB.
A -flat.vmdkle that is one of two les that comprises the base disk. The at
disk contains the raw data for the base disk. This le does not appear as a
separate le in the Datastore Browser.
A .vmsdle that contains the virtual machine's snapshot information and is
the primary source of information for the Snapshot Manager. This le
contains line entries, which dene the relationships between snapshots and
between child disks for each snapshot.
Memory file
A .vmsnle that includes the active state of the virtual machine. Capturing
the memory state of the virtual machine lets you revert to a turned on virtual
machine state. With nonmemory snapshots, you can only revert to a turned
o virtual machine state. Memory snapshots take longer to create than
nonmemory snapshots. The time the ESX host takes to write the memory
onto the disk is relative to the amount of memory the virtual machine is
congured to use.
A Take Snapshot operation creates .vmdk, -delta.vmdk, vmsd, and vmsnles.

of disks that are aached to the virtual machine.
Database of the virtual machine's snapshot information and the primary source of
information for the Snapshot Manager.
Memory state of the virtual machine at the time you take the snapshot. The le
name uses the following syntax, S1vm.snapshot1.vmsn, where S1vm is the
virtual machine name, and snapshot1 is the rst snapshot.
N A .vmsnle is created each time you take a snapshot, regardless of the
memory selection. A .vmsnle without memory is much smaller than one with
memory.
Snapshot Limitations
Snapshots can aect virtual machine performance and do not support some disk types or virtual machines
congured with bus sharing. Snapshots are useful as short-term solutions for capturing point-in-time virtual
machine states and are not appropriate for long-term virtual machine backups.
VMware does not support snapshots of raw disks, RDM physical mode disks, or guest operating
n
systems that use an iSCSI initiator in the guest.
Virtual machines with independent disks must be powered o before you take a snapshot. Snapshots of
n
powered-on or suspended virtual machines with independent disks are not supported.
Snapshots are not supported with PCI vSphere Direct Path I/O devices.
n
VMware does not support snapshots of virtual machines congured for bus sharing. If you require bus
n
sharing, consider running backup software in your guest operating system as an alternative solution. If
your virtual machine currently has snapshots that prevent you from conguring bus sharing, delete
(consolidate) the snapshots.
Snapshots provide a point-in-time image of the disk that backup solutions can use, but Snapshots are
n
not meant to be a robust method of backup and recovery. If the les containing a virtual machine are
lost, its snapshot les are also lost. Also, large numbers of snapshots are dicult to manage, consume
large amounts of disk space, and are not protected in the case of hardware failure.
Snapshots can negatively aect the performance of a virtual machine. Performance degradation is based
n
on how long the snapshot or snapshot tree is in place, the depth of the tree, and how much the virtual
machine and its guest operating system have changed from the time you took the snapshot. Also, you
might see a delay in the amount of time it takes the virtual machine to power-on. Do not run production
virtual machines from snapshots on a permanent basis.
If a virtual machine has virtual hard disks larger than 2TBs, snapshot operations can take signicantly
n
longer to nish.
Taking Snapshots of a Virtual Machine
You can take one or more snapshots of a virtual machine to capture the seings state, disk state, and
memory state at dierentspecic times. When you take a snapshot, you can also quiesce the virtual machine
les and exclude the virtual machine disks from snapshots.
When you take a snapshot, other activity that is occurring in the virtual machine might aect the snapshot
process when you revert to that snapshot. The best time to take a snapshot from a storage perspective, is
when you are not incurring a large I/O load. The best time to take a snapshot from a service perspective is
when no applications in the virtual machine are communicating with other computers. The potential for
VMware, Inc. 75
vSphere Single Host Management - VMware Host Client
problems is greatest if the virtual machine is communicating with another computer, especially in a
production environment. For example, if you take a snapshot while the virtual machine is downloading a
le from a server on the network, the virtual machine continues downloading the le and communicating its
progress to the server. If you revert to the snapshot, communications between the virtual machine and the
server are confused and the le transfer fails. Depending on the task that you are performing, you can create
a memory snapshot or you can quiesce the le system in the virtual machine.
Memory Snapshots
The default selection for taking snapshots. When you capture the virtual
machine's memory state, the snapshot retains the live state of the virtual
machine. Memory snapshots create a snapshot at a precise time, for example,
to upgrade software that is still working. If you take a memory snapshot and
the upgrade does not complete as expected, or the software does not meet
your expectations, you can revert the virtual machine to its previous state.
When you capture the memory state, the virtual machine's les do not
require quiescing. If you do not capture the memory state, the snapshot does
not save the live state of the virtual machine and the disks are crash
consistent unless you quiesce them.
Quiesced Snapshots
When you quiesce a virtual machine, VMware Tools quiesces the le system
of the virtual machine. A quiesce operation ensures that a snapshot disk
represents a consistent state of the guest le systems. Quiesced snapshots are
appropriate for automated or periodic backups. For example, if you are
unaware of the virtual machine's activity, but want several recent backups to
revert to, you can quiesce the les.
If the virtual machine is powered o or VMware Tools is not available, the
Quiesce parameter is not available. You cannot quiesce virtual machines that
have large capacity disks.
I Do not use snapshots as your only backup solution or as a long-term backup solution.
Take a Snapshot in the VMware Host Client
Snapshots capture the entire state of the virtual machine at the time you take the snapshot. You can take a
snapshot when a virtual machine is powered on, powered o, or suspended. To take a snapshot of a
suspended virtual machine, wait until the suspend operation nishes before you take a snapshot.
When you create a memory snapshot, the snapshot captures the state of the virtual machine's memory and
the virtual machine power seings. When you capture the virtual machine's memory state, snapshots that
capture the memory state of a virtual machine take longer to complete. You might also see a momentary
lapse in response over the network.
When you quiesce a virtual machine, VMware Tools quiesces the le system in the virtual machine. The
quiesce operation pauses or alters the state of running processes on the virtual machine, especially processes
that might modify information stores on the disk during a restore operation.
Application-consistent quiescing is not supported for virtual machines with IDE or SATA disks.
N Do not use VMware snapshots to backup dynamic disks on Windows. If you take a snapshot of a
dynamic disks on Windows you cannot revert to the snapshot. Snapshot technology does not have visibility
in dynamic disks and cannot preserve the quiesced state of the disk les.
Prerequisites
If you are taking a memory snapshot of a virtual machine that has multiple disks in dierent disk
n
modes, verify that the virtual machine is powered o. For example, if you have a special purpose
conguration that requires you to use an independent disk, you must power o the virtual machine
before taking a snapshot.

7Click OK.
Restoring Snapshots
To return a virtual machine to its original state, or to return to another snapshot in the snapshot hierarchy,
you can restore a snapshot.
When you restore a snapshot, you return the virtual machine's memory, seings, and the state of the virtual
machine disks to the state they were in at the time you took the snapshot. If you want the virtual machine to
be suspended, powered on, or powered o when you start it, make sure that it is in the correct state when
you take the snapshot.
You can restore snapshots in the following ways:
Revert to Latest
Snapshot
Revert To
Restoring snapshots has the following eects:
The current disk and memory states are discarded, and the virtual machine reverts to the disk and
n
memory states of the parent snapshot.
Restores the parent snapshot, one level up in the hierarchy from the You areHere position. Revert to Latest Snapshot activates the parent snapshot of the
current state of the virtual machine.
Lets you restore any snapshot in the snapshot tree and makes that snapshot
the parent snapshot of the current state of the virtual machine. Subsequent
snapshots from this point create a new branch of the snapshot tree.
Existing snapshots are not removed. You can restore those snapshots at any time.

2Right-click the virtual machine in the list, select Snapshots, and select Revert to snapshot from the pop-
up menu.
N The current state of the virtual machine will be lost unless you save it in a snapshot.
3Click Revert to revert the virtual machine to the most recent snapshot.
Deleting Snapshots
Deleting a snapshot removes the snapshot from the Snapshot Manager. The snapshot les are consolidated
and wrien to the parent snapshot disk and merge with the virtual machine base disk.
Deleting a snapshot does not change the virtual machine or other snapshots. Deleting a snapshot
consolidates the changes between snapshots and previous disk states and writes all the data from the delta
disk that contains the information about the deleted snapshot to the parent disk. When you delete the base
parent snapshot, all changes merge with the base virtual machine disk.
To delete a snapshot, a lot of information needs to be read and wrien to a disk. This can reduce virtual
machine performance until consolidation is complete. Consolidating snapshots removes redundant disks,
which improves virtual machine performance and saves storage space. The time it takes to delete snapshots
and consolidate the snapshot les depends on the amount of data that the guest operating system writes to
the virtual disks after you take the last snapshot. The required time is proportional to the amount of data the
virtual machine is writing during consolidation if the virtual machine is powered on.
78 VMware, Inc.
Chapter 3 Virtual Machine Management with the VMware Host Client
Failure of disk consolidation can reduce the performance of virtual machines. You can check whether any
virtual machines require separate consolidation operations by viewing a list. For information about locating
and viewing the consolidation state of multiple virtual machines and running a separate consolidation
operation, see vSphere Virtual Machine Administration.
Delete
Use the Delete option to remove a single parent or child snapshot from the
snapshot tree. Delete writes disk changes that occur between the state of the
snapshot and the previous disk state to the parent snapshot.
You can also use the Delete option to remove a corrupt snapshot and its les
from an abandoned branch of the snapshot tree without merging them with
the parent snapshot.
Delete All
Use the Delete All option to delete all snapshots from the Snapshot Manager.
Delete all consolidates and writes the changes that occur between snapshots
and the previous delta disk states to the base parent disk and merges them
with the base virtual machine disk.
To prevent snapshot les from merging with the parent snapshot if, for example, an update or installation
fails, rst use the Restore command to restore to a previous snapshot. This action invalidates the snapshot
delta disks and deletes the memory le. You can then use the Delete option to remove the snapshot and any
associated les.
Delete a Snapshot in the VMware Host Client
You can use the Snapshot Manager to delete a single snapshot or all snapshots in a tree.
Be careful not to accidentally delete a snapshot that you need. You cannot restore a deleted snapshot. For
example, you might want to install several browsers, a, b, and c, and capture the virtual machine state after
you install each browser. The rst, or base snapshot, captures the virtual machine with browser a and the
second snapshot captures browser b. If you restore the base snapshot that includes browser a and take a
third snapshot to capture browser c and delete the snapshot that contains browser b, you cannot return to
the virtual machine state that includes browser b.

Working with Datastores in the VMware Host Client
Datastores are logical containers, similar to le systems, that contain specic information of each storage
device and provide a uniform model for storing virtual machine les . You can also use datastores to store
ISO images, virtual machine templates, and oppy images.
Depending on the type of storage you use, datastores can be of the following types:
Virtual Machine File System (VMFS)
n
Network File System (NFS)
n
You can increase datastore capacity after you create a datastore but only if it is a VMFS datastore.

1Understanding Network File System Datastores on page 87
An NFS client built into ESXi uses the Network File System (NFS) protocol over TCP/IP to access a
designated NFS volume that is located on a NAS server. The ESXi host can mount the volume and use
it for its storage needs. vSphere supports versions 3 and 4.1 of the NFS protocol.

5Complete the NFS Datastore Mounting Process in the VMware Host Client on page 89
In the Ready to complete page you can review your conguration selections for your NFS datastore.
Understanding Network File System Datastores
An NFS client built into ESXi uses the Network File System (NFS) protocol over TCP/IP to access a
designated NFS volume that is located on a NAS server. The ESXi host can mount the volume and use it for
its storage needs. vSphere supports versions 3 and 4.1 of the NFS protocol.
Typically, the NFS volume or directory is created by a storage administrator and is exported form the NFS
server. The NFS volume is not required to be formaed with a local le system, such as VMFS. You can
mount the volume directly on ESXi hosts and use it to store and boot virtual machines in the same way that
you use VMFS datastores.
In addition to storing virtual disks on NFS datastores, you can use NFS as a central repository for ISO
images, virtual machine templates, and so on. If you use the datastore for ISO images, you can connect the
virtual machine's CD-ROM device to an ISO le on the datastore and install a guest operating system from
the ISO le.
ESXi supports the following storage capabilities on most NFS volumes:
vMotion and Storage vMotion
n
High Availability (HA) and Distributed Resource Scheduler (DRS)
n
Fault Tolerance (FT) and Host Proles
n
N NFS 4.1 does not support legacy Fault Tolerance.
ISO images, which are presented as CD-ROMs to virtual machines
n
Virtual machine snapshots
n
Virtual machines with large capacity virtual disks, or disks greater than 2TB. Virtual disks created on
n
NFS datastores are thin-provisioned by default, unless you use hardware acceleration that supports the
Reserve Space operation. NFS 4.1 does not support hardware acceleration. For information, see vSphereStorage.
NFS Storage Guidelines and Requirements
When using NFS storage, you must follow specicconguration, networking, and NFS datastore guidelines.
NFS Server Configuration Guidelines
Make sure that NFS servers you use are listed in the VMware HCL. Use the correct version for the server
n
rmware.
When conguring NFS storage, follow the recommendation of your storage vendor.
n
Ensure that the NFS volume is exported using NFS over TCP.
n
Make sure that the NFS server exports a particular share as either NFS 3 or NFS 4.1, but does not
n
provide both protocol versions for the same share. This policy needs to be enforced by the server
because ESXi does not prevent mounting the same share through dierent NFS versions.
VMware, Inc. 87
vSphere Single Host Management - VMware Host Client
NFS 3 and non-Kerberos NFS 4.1 do not support the delegate user functionality that enables access to
n
NFS volumes using nonroot credentials. If you use NFS 3 or non-Kerberos NFS 4.1, ensure that each
host has root access to the volume. Dierent storage vendors have dierent methods of enabling this
functionality, but typically this is done on the NAS servers by using the no_root_squash option. If the
NAS server does not grant root access, you might still be able to mount the NFS datastore on the host.
However, you will not be able to create any virtual machines on the datastore.
If the underlying NFS volume, on which les are stored, is read-only, make sure that the volume is
n
exported as a read-only share by the NFS server, or congure it as a read-only datastore on the ESXi
host. Otherwise, the host considers the datastore to be read-write and might not be able to open the
les.
NFS Networking Guidelines
For network connectivity, the host requires a standard network adapter.
n
ESXi supports Layer 2 and Layer 3 Network switches. If you use Layer 3 switches, ESXi hosts and NFS
n
storage arrays must be on dierent subnets and the network switch must handle the routing
information.
A VMkernel port group is required for NFS storage. You can create a new VMkernel port group for IP
n
storage on an already existing virtual switch (vSwitch) or on a new vSwitch when it is congured. The
vSwitch can be a vSphere Standard Switch (VSS) or a vSphere Distributed Switch (VDS).
If you use multiple ports for NFS trac, make sure that you correctly congure your virtual switches
n
and physical switches. For information, see the vSphere Networking documentation.
NFS 3 and non-Kerberos NFS 4.1 support IPv4 and IPv6.
n
NFS Datastore Guidelines
To use NFS 4.1, upgrade your vSphere environment to version 6.x. You cannot mount an NFS 4.1
n
datastore to hosts that do not support version 4.1.
You cannot use dierent NFS versions to mount the same datastore. NFS 3 and NFS 4.1 clients do not
n
use the same locking protocol. As a result, accessing the same virtual disks from two incompatible
clients might result in incorrect behavior and cause data corruption.
NFS 3 and NFS 4.1 datastores can coexist on the same host.
n
vSphere does not support datastore upgrades from NFS version 3 to version 4.1.
n
When you mount the same NFS 3 volume on dierent hosts, make sure that the server and folder
n
names are identical across the hosts. If the names do not match, the hosts see the same NFS version 3
volume as two dierent datastores. This error might result in a failure of such features as vMotion. An
example of such discrepancy is entering filer as the server name on one host and filer.domain.com on
the other. This guideline does not apply to NFS version 4.1.
If you use non-ASCII characters to name datastores and virtual machines, make sure that the
n
underlying NFS server oers internationalization support. If the server does not support international
characters, use only ASCII characters, or unpredictable failures might occur.
Mount an NFS Datastore in the VMware Host Client
Use the New datastore wizard to mount a Network File System (NFS) datastore in the VMware Host Client.
Prerequisites
Because NFS requires network connectivity to access data on remote servers, before conguring NFS, you
must rstcongure VMkernel networking.

Unmount a Datastore in the VMware Host Client
When you unmount a datastore in the VMware Host Client, it remains intact, but you can no longer view it
in the inventory of the host that you manage. The datastore continues to appear on other hosts that it
remains mounted on.
Do not perform any conguration operations that might result in I/O to the datastore while the unmount is
in progress.
Prerequisites
N Make sure that the datastore is not used by vSphere HA heartbeating. vSphere HA heartbeating does
not prevent you from unmouting the datastore. However, if the datastore is used for heartbeating,
unmounting it might cause the host to fail and restart all active virtual machines.
Before unmounting a datastore, also make sure that the following prerequisites are met:
No virtual machines reside on the datastore.
n
The datastore is not managed by Storage DRS.
n
Storage I/O control is disabled for this datastore.

Unmounting or Removing Datastore Fails
When you try to unmount or remove a datastore, the operation fails.
Problem
The operation to unmount or remove a datastore fails if the datastore has any opened les. For these user
operations, the vSphere HA agent closes all of the les that it has opened, for example, heartbeat les. If the
agent is not reachable by vCenter Server or the agent cannot ush out pending I/Os to close the les, a The
HA agent on host '{hostName}' failed to quiesce file activity on datastore '{dsName} fault is
triggered.
Cause
If the datastore to be unmounted or removed is used for heartbeating, vCenter Server excludes it from
heartbeating and chooses a new one. However, the agent does not receive the updated heartbeat datastores
if it is not reachable, that is, if the host is isolated or in a network partition. In such cases, heartbeat les are
not closed and the user operation fails. The operation can also fail if the datastore is not accessible because of
storage failures such as all paths down.
N When you remove a VMFS datastore, the datastore is removed from all the hosts in inventory. So if
there are any hosts in a vSphere HA cluster that are unreachable or that cannot access the datastore, the
operation fails.
Solution
Ensure that the datastore is accessible and the aected hosts are reachable.
Using Datastore File Browser in the VMware Host Client
Use the datastore le browser to manage the contents of your datastore. You can perform a number of tasks
that include uploading les to the datastore, downloading datastore les to your system, moving and
copying datastore folders or les, and creating new datastore directories.
Upload Files to a Datastore in the VMware Host Client
Use the datastore le browser to upload les to datastores on your host.
N Virtual Volumes do not support uploading les directly to the virtual datastores. You must rst
create a folder on the virtual datastore, and then upload the les into the folder.
In addition to their traditional use as a storage for virtual machine les, datastores can serve to store data or
les related to virtual machines. For example, you can upload ISO images of operating systems from a local
computer to a datastore on the host. You then use these images to install guest operating systems on the new
virtual machines.

Storage Hardware Acceleration
The hardware acceleration functionality enables the ESXi host to integrate with compliant storage arrays
and ooadspecic virtual machine and storage management operations to storage hardware. With the
storage hardware assistance, your host performs these operations faster and consumes less CPU, memory,

The hardware acceleration is supported by block storage devices, Fibre Channel and iSCSI, and NAS
devices.
For additional details, see the VMware knowledge base article at hp://kb.vmware.com/kb/1021976.

Storage Thin Provisioning in the VMware Host Client
With ESXi, you can use two models of thin provisioning, array-level and virtual-disk level thin provisioning.
Thin provisioning is a method that optimizes storage utilization by allocating storage space in a exible ondemand manner. Thin provisioning contrasts with the traditional model, called thick provisioning. With
thick provisioning, a large amount of storage space is provided in advance in anticipation of future storage
needs. However, the space might remain unused causing underutilization of storage capacity.
The VMware thin provisioning features help you eliminate storage underutilization problems at the
datastore and storage array level.
Create Thin Provisioned Virtual Disks in the VMware Host Client
To save storage space, you can create thin provisioned virtual disks. The thin provisioned virtual disk starts
small and grows as more disk space is required. You can create thin disks only on the datastores that
support disk-level thin provisioning.
The following procedure assumes that you are creating a new virtual machine. For more information, see
“Creating a Virtual Machine in the VMware Host Client,” on page 33.

Configuring Software iSCSI Adapters in the VMware Host Client
With the software-based iSCSI implementation, you can use standard NICs to connect your host to a remote
iSCSI target on the IP network. The software iSCSI adapter that is built into ESXi communicates with the
physical NICs through the network stack.
N Before you can use the software iSCSI adapter, you must set up networking, activate the adapter, and
congure parameters such as CHAP.
The iSCSI adapter congurationworkow includes the following procedures:
Enabling iSCSI on your host. See“Enable iSCSI for an ESXi Host in the VMware Host Client,” on
n

Adding a port binding. See “Add Port Binding in the VMware Host Client,” on page 99
n
Removing port binding. See“Remove Port Binding in the VMware Host Client,” on page 100

Setting Up iSCSI Network
Software and dependent hardware iSCSI adapters depend on VMkernel networking. If you use the software
or dependent hardware iSCSI adapters, you must congure connections for the trac between the iSCSI
component and the physical network adapters.
Conguring the network connection involves creating a virtual VMkernel adapter for each physical network
adapter. You then associate the VMkernel adapter with an appropriate iSCSI adapter. This process is called
port binding.
For specic considerations on when and how to use network connections with software iSCSI, see the
VMware knowledge base article at hp://kb.vmware.com/kb/2038869.
Multiple Network Adapters in iSCSI Configuration
If your host has more than one physical network adapter for software and dependent hardware iSCSI, use
the adapters for multipathing.
You can connect the software iSCSI adapter with any physical NICs available on your host. The dependent
iSCSI adapters must be connected only to their own physical NICs.
N Physical NICs must be on the same subnet as the iSCSI storage system they connect to.
Chapter 4 Managing Storage in the VMware Host Client
The iSCSI adapter and physical NIC connect through a virtual VMkernel adapter, also called virtual
network adapter or VMkernel port. You create a VMkernel adapter (vmk) on a vSphere switch (vSwitch)
using 1:1 mapping between each virtual and physical network adapter.
One way to achieve the 1:1 mapping when you have multiple NICs, is to designate a separate vSphere
switch for each virtual-to-physical adapter pair.
N If you use separate vSphere switches, you must connect them to dierent IP subnets. Otherwise,
VMkernel adapters might experience connectivity problems and the host will fail to discover iSCSI LUNs.
The following examples show congurations that use vSphere standard switches, but you can use
distributed switches as well. For more information about vSphere distributed switches, see the vSphereNetworking documentation.

Figure 4‑2. 1:1 adapter mapping on separate vSphere standard switches
An alternative is to add all NICs and VMkernel adapters to a single vSphere standard switch. In this case,
you must override the default network setup and make sure that each VMkernel adapter maps to only one
corresponding active physical adapter.
N You must use the single vSwitch conguration if VMkernel adapters are on the same subnet.

Guidelines for Using iSCSI Port Binding in ESXi
You can use multiple VMkernel adapters bound to iSCSI to have multiple paths to an iSCSI array that
broadcasts a single IP address.
When you use port binding for multipathing, follow these guidelines:
iSCSI ports of the array target must reside in the same broadcast domain and IP subnet as the VMkernel
n
adapters.
All VMkernel adapters used for iSCSI port binding must reside in the same broadcast domain and IP
n
subnet.
All VMkernel adapters used for iSCSI connectivity must reside in the same virtual switch.
n
Port binding does not support network routing.
n
Do not use port binding when any of the following conditions exist:
Array target iSCSI ports are in a dierent broadcast domain and IP subnet.
n
VMkernel adapters used for iSCSI connectivity exist in dierent broadcast domains, IP subnets, or use
n
dierent virtual switches.
Routing is required to reach the iSCSI array.
n
Add Port Binding in the VMware Host Client
Use the VMware Host Client to bind an iSCSI adapter with a VMkernel adapter on your host.

Configuring Discovery Addresses for iSCSI Adapters
You need to set up target discovery addresses, so that the iSCSI adapter can determine which storage
resource on the network is available for access.
The ESXi system supports these discovery methods:
Dynamic Discovery
Static Discovery
Set Up a Static Target in the VMware Host Client
With iSCSI initiators, you can use static discovery to manually enter information for the targets.
When you set up Static Discovery, you can only add new iSCSI targets. You cannot change the IP address,
DNS name, iSCSI target name, or port number of an existing target. To make changes, remove the existing
target and add a new one.
Also known as SendTargets discovery. Each time the initiator contacts a
specied iSCSI server, the initiator sends the SendTargets request to the
server. The server responds by supplying a list of available targets to the
initiator. The names and IP addresses of these targets appear on the StaticDiscovery tab. If you remove a static target added by dynamic discovery, the
target might be returned to the list the next time a rescan happens, the iSCSI
adapter is reset, or the host is rebooted.
N With software and dependent hardware iSCSI, ESXi lters target
addresses based on the IP family of the iSCSI server address specied. If the
address is IPv4, IPv6 addresses that might come in the SendTargets response
from the iSCSI server are ltered out. When DNS names are used to specify
an iSCSI server, or when the SendTargets response from the iSCSI server has
DNS names, ESXi relies on the IP family of the rst resolved entry from DNS
lookup.
In addition to the dynamic discovery method, you can use static discovery
and manually enter information for the targets. The iSCSI adapter uses a list
of targets that you provide to contact and communicate with the iSCSI
servers.
