Introduction
VMware®ESX Server™ software provides the rapid creation of multiple
virtual machines (VMs) on a single physical server. These VMs each run in a
resource-isolated, secure environment and include a Microsoft
Linux™, or Novell
®
NetWare® operating system (OS) with their associated
applications. The ESX Server software has a virtualization layer that
allocates virtualized Dell resources to VMs and a Service Console – a
management interface for the VMware virtualization layer.
the ESX Server architecture.
Figure 1-1. VMware ESX Server Architecture
®
Windows,
Figure 1-1
shows
VMware VirtualCenter is a management application that monitors and
manages virtual machines distributed across ESX Server installations, as well
as the ESX Server systems themselves. VirtualCenter can show global task
lists, each individual ESX Server, or each individual VM.
When VirtualCenter-managed ESX Server farms have a common
Storage Area Network (SAN), they can take advantage of VMotion™
technology. This technology allows for the “hot” migration of a running VM.
A live, state-full application, with its OS, can be moved from one
PowerEdge™ server running ESX Server to another. This migration is
transparent to the end users, who are not aware that it is taking place.
VMotion technology provides dynamic scaling, performance, and

zero-downtime maintenance. If a physical server needs servicing, it can be
vacated; that is, all running VMs are moved to other ESX Server systems
without affecting users. The vacant system can be shutdown, repaired, then
placed back into service at which time VMs can be migrated back to it – all
without impacting availability to end users.
Dell configurations of ESX Server software and VirtualCenter allow users to:
• Implement server consolidation
• Deliver high availability and guaranteed service levels
• Streamline testing and deployment
• Scale hardware and software infrastructure
www.dell.com | support.dell.com
• Upgrade to current and standard hardware, independently of
software upgrades

Understanding Dell Configurations
For this release, Dell has qualified a base server configuration for use with
ESX Server 2.1.2 software. A single server can be used in a "stand-alone"
mode, or one or more servers can be connected to a shared SAN through a
switch. VMotion technology is available when two or more servers share a
common SAN. VirtualCenter may be used to manage servers in any of these
configurations, and is required to initiate VMotion events.
NOTE: USB devices are not supported with ESX Server 2.1.2 software default
installation and configuration. Even if USB is enabled in the BIOS, the
ESX Server 2.1.2 software will disable it by default. If you need to use USB with
ESX Server 2.1.2, see the VMware knowledge base article 1326 - Using USB
When ESX Server Disables It.

Understanding ESX Server Components
• ESX Server – VMware virtualization software infrastructure installed
on PowerEdge Servers for partitioning and consolidating systems,
providing a platform for VMs.
• Service Console – a management interface for VMware virtualization
layer, which enables management of the ESX Server software remotely
from a web browser.
• Management User Interface (MUI) – Web based interface used to
configure the ESX Server software.
• Remote Console - Windows application, or Linux application that runs
locally on a PowerEdge Server. This enables remote console access to
Virtual Machines.
• Virtual Machine - an encapsulation of an operating system and its
application with dynamic features beyond physical machines.
NOTE: An explanation of the VMware ESX Server software component product
license information can be found at the www.dell.com/vmware under the
Product and Services tab.
Understanding VirtualCenter Components
• VirtualCenter Server - a management server for network-connected
VMware ESX Server systems.
• VirtualCenter Client - the client interface for end users and
administrators to access the VirtualCenter server. This is often run on
the same physical machine as the VirtualCenter Server.
• VirtualCenter Database - backend database used by the
VirtualCenter Server. This database can either be located on the same
server as the VirtualCenter Server or a separate server with
Microsoft SQL or Oracle database.
Deployment Guide 11
• Template Repository - is a persistent storage location that maintains
VM templates. These are run-able images of OSs, optionally including
applications. The images can be rapidly cloned for use by
ESX Server systems.
NOTE: Cloning is deployment of a new VM and not migration of an
existing VM.
• VirtualCenter Agent - an agent that is installed on each
Dell PowerEdge Server with ESX Server software that is part of a
VirtualCenter farm. This agent allows the ESX Server software to be
managed by VirtualCenter and allows for the VMotion capability. This
agent is installed automatically when a host is added to VirtualCenter.
www.dell.com | support.dell.com
NOTE: If you are installing ESX Server 2.1.2 software in your network for the
first time and are using VirtualCenter, be sure to install or upgrade to
VirtualCenter 1.1 first. VirtualCenter 1.1 contains the correct version of the
VirtualCenter agent for ESX Server 2.1.2. This agent will be installed
automatically on ESX Server 2.1.2 systems when VirtualCenter discovers them.

Installation of ESX Server 2.1.2 Software
NOTE: ESX Server 2.1.2 software is only supported with VirtualCenter 1.1. If you
are using VirtualCenter to manage your ESX Server systems, you MUST
upgrade your VirtualCenter installation to VirtualCenter 1.1 BEFORE you
upgrade your ESX Server software to 2.1.2.
This section describes the important guidelines for the installation of
ESX Server 2.1.2 software on Dell servers. For step by step installation
instructions and requirements of the ESX Server 2.1.2 software, see the
12 Deployment Guide
ESX Server 2.1 Installation Guide
from VMware. This document comes with
the installation CD and can also be found at:
http://www.vmware.com/pdf/esx/esx21install.pdf
.
Before Installation
Planning
Planning is an important phase in the installation of the ESX Server
software. A well planned installation will require fewer reconfigurations
and less tuning in the future. Gather the following information prior
to installation:
• Determine the number of VMs that will run on the ESX Server
installation and their corresponding workloads.
• Size the resource requirements for the VMs, such as
CPU requirements, amount of memory, number of NICs, etc. For more
information on sizing see the sizing guidelines document at
www.dell.com/vmware
.
• Size the resource requirements for the Service Console.
• Identify resource sensitive VMs and dedicate the required resources to
those VMs (for example, dedicating a NIC to a file server).
• Gather the required network information, such as IP addresses,
gateways, and so on.
• Determine the most appropriate local disk partitioning scheme. (See
below for recommended disk partitioning.)
VirtualCenter
If you are using VirtualCenter to manage your ESX Server systems, be sure
to upgrade it to VirtualCenter version 1.1 before upgrading any of the
ESX Server systems to 2.1.2.
RAID Configuration
Before installing the ESX Server software make sure that the disks have the
required RAID configurations. Use the highest RAID level available, given
the number of local disk drives. For two disk drives, use RAID 1. For more
than two disk drives, use RAID 5 for improved performance. RAID 0 is not
recommended, since it does not provide redundancy of data.
Deployment Guide 13
Utility Partition
New Dell Servers ship with the Dell Utility Partition (UP) pre-installed.
The UP is a bootable disk partition that contains Dell diagnostic utilities
and other software useful in maintaining the hardware. It is accessed by
pressing the <F10> key at system boot time. Dell recommends that you
keep the UP on your ESX Server system. If the UP has been deleted, it can
be restored using the
information, see
NOTE: It is recommended to run the Memory Diagnostic test found in the Utility
Partition before the installation of ESX Server software.

Service Console Configuration
During device allocation, the memory reserved for Service Console is
configured. The amount of memory for the Service Console depends on the
number of virtual machines that are planned to run on the ESX Server
system. It is recommended that more memory (around 128 MB) be allocated
to the Service Console if Dell OpenManage is installed. The amount of
memory dedicated to the Service Console can be changed at any time, but
requires a reboot of the ESX Server system.
Deployment Guide 15
After Installation
After the installation of the ESX Server software in graphics mode, execute
the following steps to complete the installation.
• Create and activate a
over-provisioning of the memory to the VMs and results in better
resource management.
• Give a name to the local VMFS partition. This will improve usability
and also preserve access to the local VM disk files, even if one or more
peripheral devices are added or removed.
• Create a

SAN Environment Setup with
ESX Server Software
Advanced features such as VMotion technology require a Storage Area
Network (SAN) environment using Dell | EMC CX300, CX500, or CX700
storage devices. Setting up the SAN for ESX Server systems does not require
any special steps. This section provides a quick overview of the general
concepts of a SAN and the steps needed to set up a SAN environment.
LUN:
more physical disks.
RAID Group:
order to use the LUNs one has to create a RAID group and bind LUNs to it.
Storage Group:
more LUNs. A server in a Storage Group can only access LUNs which are in
the same Storage Group. Storage Groups are typically used to implement
access control.
A Logical Unit Number (LUN) is a unique identifier for a set of one or
NOTE: A single disk can encompass more that one LUN, but it is not
recommended for performance reasons.
A RAID Group is a collection of one or more physical disks. In
A Storage Group is a set of one or more servers and one or
16 Deployment Guide
In order to create and use Storage Groups in Navisphere, the Access LogicTM
option must be enabled.
NOTE: Access Logic is a software component of Navisphere® which needs to
be installed at the storage system.
Zoning:
Zoning controls access between fiber channel devices. Zoning at
the switch would determine the group servers that can access a particular
storage device.
The typical steps involved in setting up a SAN are:
1
Install and setup the CX300, CX500, or CX700 storage device.
2
Configure zoning at the switch level.
3
Create RAID groups.
4
Create and bind LUNs.
NOTE: When creating the LUNs, select Auto Assign to assign the LUN
to the storage processor. This is highly recommended for better
load balancing.
Manually register the servers (hosts) connected to the SAN (see below
5
for step by step instructions).
6
Create Storage Groups containing the servers and the LUNs.

Dell OpenManage in a
VMware ESX Server Environment
OpenManage Software Overview
Dell OpenManage systems management software is a suite of application
programs for PowerEdge systems. This software allows you to manage your
system with proactive monitoring, diagnosis, notification, and remote
access. Each system that you plan to manage with Dell OpenManage
software products is called a
managed system
. Managed system applications
18 Deployment Guide
include Server Administrator, and remote access controller (RAC) software.
Server Administrator provides a comprehensive, one-to-one systems
management solution in two ways: from an integrated, Web browser-based
GUI (the Server Administrator home page) and from a command line
interface (CLI) through the operating system. (For ESX Server systems,
Server Administrator is installed in the Service Console.) Server
Administrator is designed for system administrators to both locally and
remotely manage systems on a network. Server Administrator allows system
administrators to focus on managing their entire network by providing
comprehensive one-on-one system management. A management station can
be used to remotely manage one or more managed systems from a central
location. By installing IT Assistant on a management station, you can
effectively manage from one to hundreds of remote managed systems.

NOTE: Managed system applications such as Server Administrator, and remote
access controller (RAC) software are not used inside the virtual machines
because the software would only see the virtualized hardware and not the
physical hardware.
NOTE: Dell OpenManage Server Administrator will run within the VMware
Service Console and can be used to manage the server components. Devices
which are dedicated exclusively to the VMkernel are not reported by Dell
OpenManage Server Administrator and Service Console. Server Administrator
can only monitor hardware components that are shared with the VMware
Service Console. The following devices are dedicated exclusively to VMkernel:
• CPU1, CPU2, and CPU3 on PE6650 or CPU1 on PE 2850 and PE 1850
• Network Interface Cards and Host Bus Adapter (HBA) which are dedicated

Guest OS Performance Tuning Tips
The following tuning tips significantly improve performance over the
Guest OS and VMTools default installations and are highly recommended
for Dell qualified configurations.
NOTE: The actual results of the tuning tips provided here depend on the
configuration and will vary accordingly.
• Maximize ESX Server system tuning across VMs prior to individual
VM Guest OS tuning. See VMware ESX Server 2.1 product
documentation at
CPU, memory, and disk bandwidth across VMs.
• Ensure VMware Tools are installed to improve video and
www.dell.com | support.dell.com
mouse performance and other benefits.
• Disable all CPU-intensive screen savers.
• Ensure that each VM's guest OS type is correct in its configuration file.
• To ensure best device performance ensure that you are using supported
devices. See
www.dell.com/vmware
www.vmware.com/support/esx21/doc
for details.
for scheduling
• For best performance, VMs should use separate resources from the
Service Console, specifically Ethernet NIC cards.
• Ideally, each VM should be running only one application.
• For CPU-bound workloads, enable hyper-threading on the
ESX Server system.
• For shared resources, pair VMs that will not compete for the
same resource.
• Avoid using the two legacy Serial (COM) ports or Parallel (LPT) port
devices by VMs.
• Disconnect CD-ROM device from all the VMs.
• For all VMs that do not require PXE boot, it is highly recommended to
replace
vlance
with
vmxnet
device as the virtual NIC. It is included and
documented in VMware Tools. This will drastically improve
performance when Gigabit Ethernet is used and the VMs have high
bandwidth requirements.
22 Deployment Guide
• Tradeoffs between memory and CPU resources:
• If VMs are CPU-bound and RAM is under-utilized, then turn off
page sharing. You can achieve this from the ESX Server
Management User Interface (MUI):
• Choose
Options
• Next, click on
•Set
Mem.ShareScanTotal
tab.
Advanced Settings.
to 0. (The default is 200.)
• If VM peak memory is bursty, then decrease idle memory tax rate.
From ESX MUI:
• Choose
• Next, click on
•Set
Options
Advanced Settings.
Mem.IdleTax
tab.
to the rate of your choice. (The default
is 75%.)
• VMware performance metrics can be accessed by exploring the
directory structure at /proc/vmware within the Service Console.
• For better backup practices, it is recommended to create two virtual
disks for each virtual machine: one virtual disk containing
OS/application installation files and the other virtual disk containing
user data. This allows for more frequent backup of the data virtual disk.
• Identify the limited resource by application type:

Microsoft Windows Tuning Tips
• Use Perfmon to profile the Windows application and identify its key
resource, then:
• Isolate or limit sharing to each VM's key resource.
• Save perfmon-tuned, gold images for cloning. For example:
• Install Windows, Windows service packs and patches,
VMware Tools, anti-virus, management agents, backup agent,
application, application service packs, and patches. Save this
pre-tuned golden master.
• Do performance profiling with perfmon to determine the
www.dell.com | support.dell.com
optimal, tuned golden master to save for cloning. Although
you may want to retain images at several installation points for
future use as golden masters, note that performance tuning is
after the full installation, including application.
• Windows Terminal Service (WTS) performance is greatly improved by
setting the workload attribute to "Terminal Services". This option can
be enabled in the MUI when creating the virtual machine, or by adding
the following line in the configuration file of the virtual machine:
workload = "TerminalServices"
• Similarly, Citrix MetaFrame XP performs better by installing hotfix
XE102W014 in the guest Windows OS.
Microsoft Windows 2003 Tuning Tips
• Dell recommends that you do all performance tuning experiments
prior to activating your license for Windows 2003 operating system.
Microsoft Windows 2000 Tuning Tips
• After installing VMware Tools, you need to change your Windows 2000
screen area to be greater than 640x480 pixels; if you do not change it,
Windows 2000 uses the standard VGA driver, degrading performance.
• Use the VMware SCSI driver, supplied within VMware Tools, instead of
Microsoft's Buslogic driver.
24 Deployment Guide
Microsoft NT4 Tuning Tips
• Virtual disks support DMA transfers for better performance.
See
www.vmware.com/support/esx21
for instructions on how to enable
this feature.
• Service Pack 6a is highly recommended for performance and
compatibility.
Linux Tuning Tips
• At the end of Linux OS installation on the VM, make sure that "Text"
mode is selected for the Login screen instead of "Graphical" mode. For
Linux, installation of VMware Tools is a semi-manual process. See the
Guest Operating System Installation Guide
for more information.
• Ensure that VMware Tools is installed in the guest OS prior to starting
the X server. For example, Skip X Configuration in the video card
installation. One benefit is that you get accelerated SVGA X server,
instead of the X server installed for example, with Red Hat Linux 9.
To install VMware tools see the manual for your VMware product.
NOTE: Depending on the Linux distribution and kernel version, the
VMware tools installation script may need to re-compile the VMware tools
agent. This will require that the "make" utility and a C-compiler are resident on
the Linux guest OS.
