View Architecture Planning
View Architecture Planning provides an introduction to VMware Horizon™ with View™, including a
description of its major features and deployment options and an overview of how the components are
typically set up in a production environment.
This guide answers the following questions:
Does View solve the problems you need it to solve?
n
Would it be feasible and cost-effective to implement a View solution in your enterprise?
n
Not all features and capabilities of VMware Horizon with View are available in all editions. For a
comparison of feature sets in each edition, see
http://www.vmware.com/files/pdf/products/horizon-view/VMware-Horizon-View-Pricing-LicensingFAQ.pdf.
To help you protect your installation, this guide also provides a discussion of security features.
Intended Audience
This information is intended for IT decision makers, architects, administrators, and others who need to
familiarize themselves with the components and capabilities of View. With this information, architects and
planners can determine whether View satisfies the requirements of their enterprise for efficiently and
securely delivering Windows desktops and applications to their end users. The example architecture helps
planners understand the hardware requirements and setup effort required for a large-scale deployment.

Introduction to View 1
With View, IT departments can run remote desktops and applications in the datacenter and deliver these
desktops and applications to employees as a managed service. End users gain a familiar, personalized
environment that they can access from any number of devices anywhere throughout the enterprise or from
home. Administrators gain centralized control, efficiency, and security by having desktop data in the
datacenter.
This chapter includes the following topics:
“Advantages of Using View,” on page 7
n
“View Features,” on page 9
n
“How the Components Fit Together,” on page 11
n
“Integrating and Customizing View,” on page 14
n
Advantages of Using View
When you manage enterprise desktops with View, the benefits include increased reliability, security,
hardware independence, and convenience.
Reliability and Security
Desktops and applications can be centralized by integrating with VMware vSphere® and virtualizing server,
storage, and networking resources. Placing desktop operating systems and applications on a server in the
datacenter provides the following advantages:
Access to data can easily be restricted. Sensitive data can be prevented from being copied onto a remote
n
employee's home computer.
RADIUS support provides flexibility when choosing among two-factor authentication vendors.
n
Supported vendors include RSA SecureID, VASCO DIGIPASS, SMS Passcode, and SafeNet, among
others.
Integration with Workspace means that end users have on-demand access to remote desktops through
n
the same Web-based application catalog they use to access SaaS, Web, and Windows applications.
Inside a remote desktop, users can also use Workspace Catalog to access applications.
The ability to provision remote desktops with pre-created Active Directory accounts addresses the
n
requirements of locked-down Active Directory environments that have read-only access policies.
Data backups can be scheduled without considering when end users' systems might be turned off.
n
VMware, Inc.
7
View Architecture Planning
Remote desktops and applications that are hosted in a datacenter experience little or no downtime.
n
Virtual machines can reside on high-availability clusters of VMware servers.
Virtual desktops can also connect to back-end physical systems and Microsoft Remote Desktop Services
(RDS) hosts.
Convenience
The unified management console is built for scalability so that even the largest View deployments can be
efficiently managed from a single management interface. Wizards and dashboards enhance the workflow
and facilitate drilling down to see details or change settings. Figure 1-1 provides an example of the browserbased user interface for View Administrator.
Figure 1‑1. Administrative Console Showing the Dashboard View
Another feature that increases convenience is the VMware remote display protocol, PCoIP. The PCoIP (PCover-IP) display protocol delivers an end-user experience equal to the current experience of using a physical
PC:
On LANs, the display is faster and smoother than traditional remote displays.
n
On WANs, the display protocol can compensate for an increase in latency or a reduction in bandwidth,
n
ensuring that end users can remain productive regardless of network conditions.
Manageability
Provisioning desktops and applications for end users is a quick process. No one is required to install
applications one by one on each end user's physical PC. End users connect to a remote application or a
remote desktop complete with applications. End users can access their same remote desktop or application
from various devices at various locations.
Using VMware vSphere to host virtual desktops and RDS host servers provides the following benefits:
Administration tasks and management chores are reduced. Administrators can patch and upgrade
n
applications and operating systems without touching a user's physical PC.
8 VMware, Inc.
Chapter 1 Introduction to View
Integration with Workspace means that IT managers can use the Web-based Workspace administration
n
interface to monitor user and group entitlements to remote desktops.
With View Persona Management, physical and virtual desktops can be centrally managed, including
n
user profiles, application entitlement, policies, performance, and other settings. Deploy View Persona
Management to physical desktop users prior to converting to virtual desktops.
Storage management is simplified. Using VMware vSphere, you can virtualize volumes and file
n
systems to avoid managing separate storage devices.
With vSphere 5.5 Update 1 or a later release, you can use Virtual SAN, which virtualizes the local
n
physical solid-state disks and hard disk drives available on ESXi™ hosts into a single datastore shared
by all hosts in a cluster. You specify only one datastore when creating a desktop pool, and the various
components, such as virtual machine files, replicas, user data, and operating system files, are placed on
either SSD disks or hard drive disks, as appropriate.
You manage virtual machine storage requirements, such as capacity, performance, and availability, in
the form of default storage policy profiles, which get created automatically when you create a desktop
pool.
With the View storage accelerator, the IOPS storage load is dramatically reduced, supporting end-user
n
logins at larger scales without requiring any special storage array technology.
If remote desktops use the space-efficient disk format available with vSphere 5.1 and later, stale or
n
deleted data within a guest operating system is automatically reclaimed with a wipe and shrink
process.
Hardware Independence
Remote desktops and applications are hardware-independent. For example, because a remote desktop runs
on a server in the datacenter and is only accessed from a client device, a remote desktop can use an
operating system that might not be compatible with the hardware of the client device.
For example, although Windows 8 can run only on Windows 8-enabled devices, you can install Windows 8
in a virtual machine and use that virtual machine on a PC that is not Windows 8-enabled.
Remote desktops run on PCs, Macs, thin clients, PCs that have been repurposed as thin clients, tablets, and
phones. Remote applications run on a subset of these devices. New device support is added quarterly.
If you use the HTML Access feature, end users can open a remote desktop inside a browser, without having
to install any client application on the client system or device.
View Features
Features included in View support usability, security, centralized control, and scalability.
The following features provide a familiar experience for the end user:
On Microsoft Windows client devices, print from a virtual desktop to any local or networked printer
n
that is defined on the Windows client device. This virtual printer feature solves compatibility issues and
does not require you to install additional print drivers in a virtual machine.
On most client devices, use the location-based printing feature to map to printers that are physically
n
near the client system. Location-based printing does require that you install print drivers in the virtual
machine.
Use multiple monitors. With PCoIP multiple-monitor support, you can adjust the display resolution
n
and rotation separately for each monitor.
Access USB devices and other peripherals that are connected to the local device that displays your
n
virtual desktop.
VMware, Inc. 9
View Architecture Planning
You can specify which types of USB devices end users are allowed to connect to. For composite devices
that contain multiple types of devices, such as a video input device and a storage device, you can split
the device so that one device (for example, the video input device) is allowed but the other device (for
example, the storage device) is not.
Use View Persona Management to retain user settings and data between sessions even after the desktop
n
has been refreshed or recomposed. View Persona Management has the ability to replicate user profiles
to a remote profile store (CIFS share) at configurable intervals.
You can also use a standalone version of View Persona Management on physical computers and virtual
machines that are not managed by View.
View offers the following security features, among others:
Use two-factor authentication, such as RSA SecurID or RADIUS (Remote Authentication Dial-In User
n
Service), or smart cards to log in.
Use pre-created Active Directory accounts when provisioning remote desktops and applications in
n
environments that have read-only access policies for Active Directory.
Use SSL tunneling to ensure that all connections are completely encrypted.
n
Use VMware High Availability to ensure automatic failover.
n
Scalability features depend on the VMware virtualization platform to manage both desktops and servers:
Integrate with VMware vSphere to achieve cost-effective densities, high levels of availability, and
n
advanced resource allocation control for your remote desktops and applications.
Use the View storage accelerator feature to support end-user logins at larger scales with the same
n
storage resources. This storage accelerator uses features in the vSphere 5 platform to create a host
memory cache of common block reads.
Configure View Connection Server to broker connections between end users and the remote desktops
n
and applications that they are authorized to access.
Use View Composer to quickly create desktop images that share virtual disks with a master image.
n
Using linked clones in this way conserves disk space and simplifies the management of patches and
updates to the operating system.
The following features provide centralized administration and management:
Use Microsoft Active Directory to manage access to remote desktops and applications and to manage
n
policies.
Use View Persona Management to simplify and streamline migration from physical to virtual desktops.
n
Use the Web-based administrative console to manage remote desktops and applications from any
n
location.
Use View Administrator to distribute and manage applications packaged with VMware ThinApp™.
n
Use a template, or master image, to quickly create and provision pools of desktops.
n
Send updates and patches to virtual desktops without affecting user settings, data, or preferences.
n
Integrate with Workspace™ so that end users can access remote desktops through the Workspace user
n
portal on the Web, as well as use the Workspace user portal on the Web from inside a remote desktop.
Integrate with Mirage™ to manage locally installed virtual machine desktops and to deploy and update
n
applications on dedicated full-clone remote desktops without overwriting user-installed applications.

View Architecture Planning
Client Devices
A major advantage of using View is that remote desktops and applications follow the end user regardless of
device or location. Users can access their personalized virtual desktop or remote application from a
company laptop, their home PC, a thin client device, a Mac, or a tablet or phone.
End users open Horizon Client to display their remote desktops and applications. Thin client devices use
View thin client software and can be configured so that the only application that users can launch directly
on the device is View Thin Client. Repurposing a legacy PC into a thin client desktop can extend the life of
the hardware by three to five years. For example, by using View on a thin desktop, you can use a newer
operating system such as Windows 7 on older desktop hardware.
If you use the HTML Access feature, end users can open a remote desktop inside a browser, without having
to install any client application on the client system or device.
View Connection Server
This software service acts as a broker for client connections. View Connection Server authenticates users
through Windows Active Directory and directs the request to the appropriate virtual machine, physical PC,
or Microsoft RDS host.
View Connection Server provides the following management capabilities:
Authenticating users
n
Entitling users to specific desktops and pools
n
Assigning applications packaged with VMware ThinApp to specific desktops and pools
n
Managing remote desktop and application sessions
n
Establishing secure connections between users and remote desktops and applications
n
Enabling single sign-on
n
Setting and applying policies
n
Inside the corporate firewall, you install and configure a group of two or more View Connection Server
instances. Their configuration data is stored in an embedded LDAP directory and is replicated among
members of the group.
Outside the corporate firewall, in the DMZ, you can install and configure View Connection Server as a
security server. Security servers in the DMZ communicate with View Connection Servers inside the
corporate firewall. Security servers ensure that the only remote desktop and application traffic that can enter
the corporate data center is traffic on behalf of a strongly authenticated user. Users can access only the
resources that they are authorized to access.
Security servers offer a subset of functionality and are not required to be in an Active Directory domain. You
install View Connection Server in a Windows Server 2008, Windows Server 2012, or Windows Server 2012
R2 server, preferably on a VMware virtual machine.
IMPORTANT It is possible to create a View setup that does not use View Connection Server. If you install the
View Agent Direct Connect Plugin in a remote virtual machine desktop, the client can connect directly to the
virtual machine. All the remote desktop features, including PCoIP, HTML Access, RDP, USB redirection,
and session management work in the same way, as if the user had connected through View Connection
Server. For more information, see View Agent Direct-Connection Plugin Administration.
12 VMware, Inc.
Chapter 1 Introduction to View
Horizon Client
The client software for accessing remote desktops and applications can run on a tablet, a phone, a Windows,
Linux, or Mac PC or laptop, a thin client, and more.
After logging in, users select from a list of remote desktops and applications that they are authorized to use.
Authorization can require Active Directory credentials, a UPN, a smart card PIN, or an RSA SecurID or
other two-factor authentication token.
An administrator can configure Horizon Client to allow end users to select a display protocol. Protocols
include PCoIP and Microsoft RDP for remote desktops. The speed and display quality of PCoIP rival that of
a physical PC.
Features differ according to which Horizon Client you use. This guide focuses on Horizon Client for
Windows. The following types of clients are not described in detail in this guide:
Details about Horizon Client for tablets, Linux clients, and Mac clients. See the Horizon Client
n
documentation at https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Details about the HTML Access Web client, which allows you to open a remote desktop inside a
n
browser. No Horizon Client application is installed on the client system or device. See the
Horizon Client documentation at
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Various third-party thin clients and zero clients, available only through certified partners.
n
View Open Client, which supports the VMware partner certification program. View Open Client is not
n
an official client application and is not supported as such.
VMware Horizon User Web Portal
From a Web browser on a client device, end users can connect to remote desktops and applications through
the browser, automatically start Horizon Client if it is installed, or download the Horizon Client installer.
When you open a browser and enter the URL of a View Connection Server instance, the Web page that
appears contains links to the VMware Downloads site for downloading Horizon Client. The links on the
Web page are configurable, however. For example, you can configure the links to point to an internal Web
server, or you can limit which client versions are available on your own View Connection Server.
If you use the HTML Access feature, the Web page also displays a link for accessing remote desktops inside
a supported browser. With this feature, no Horizon Client application is installed on the client system or
device. For more information, see the Horizon Client documentation at
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
View Agent
You install the View Agent service on all virtual machines, physical systems, and Microsoft RDS hosts that
you use as sources for remote desktops and applications. On virtual machines, this agent communicates
with Horizon Client to provide features such as connection monitoring, virtual printing, View Persona
Management, and access to locally connected USB devices.
If the desktop source is a virtual machine, you first install the View Agent service on that virtual machine
and then use the virtual machine as a template or as a parent of linked clones. When you create a pool from
this virtual machine, the agent is automatically installed on every remote desktop.
You can install the agent with an option for single sign-on. With single sign-on, users are prompted to log in
only when they connect to View Connection Server and are not prompted a second time to connect to a
remote desktop or application.
VMware, Inc. 13
View Architecture Planning
View Administrator
This Web-based application allows administrators to configure View Connection Server, deploy and
manage remote desktops and applications, control user authentication, and troubleshoot end user issues.
When you install a View Connection Server instance, the View Administrator application is also installed.
This application allows administrators to manage View Connection Server instances from anywhere
without having to install an application on their local computer.
View Composer
You can install this software service on a vCenter Server instance that manages virtual machines or on a
separate server. View Composer can then create a pool of linked clones from a specified parent virtual
machine. This strategy reduces storage costs by up to 90 percent.
Each linked clone acts like an independent desktop, with a unique host name and IP address, yet the linked
clone requires significantly less storage because it shares a base image with the parent.
Because linked-clone desktop pools share a base image, you can quickly deploy updates and patches by
updating only the parent virtual machine. End users' settings, data, and applications are not affected.
Although you can install View Composer on its own server host, a View Composer service can operate with
only one vCenter Server instance. Similarly, a vCenter Server instance can be associated with only one View
Composer service.
vCenter Server
This service acts as a central administrator for VMware ESXiservers that are connected on a network.
vCenter Server, provides the central point for configuring, provisioning, and managing virtual machines in
the datacenter.
In addition to using these virtual machines as sources for virtual machine desktop pools, you can use virtual
machines to host the server components of View including View Connection Server instances, Active
Directory servers, Microsoft RDS hosts, and vCenter Server instances.
You can install View Composer on the same server as vCenter Server or on a different server.vCenter Server
then manages the assignment of the virtual machines to physical servers and storage and manages the
assignment of CPU and memory resources to virtual machines.
You can install vCenter Server either as a VMware virtual appliance or install vCenter Server in a Windows
Server 2008 R2 server, a Windows Server 2012 server, or a Windows Server 2012 R2 server, preferably on a
VMware virtual machine.
Integrating and Customizing View
To enhance the effectiveness of View in your organization, you can use several interfaces to integrate View
with external applications or to create administration scripts that you can run from the command line or in
batch mode.
Integrating with Other VMware Horizon Components
VMware Workspace
You can integrate Workspace with View to provide the following benefits to
IT managers and end users:
End users have on-demand access to remote desktops and applications
n
through the same user portal on the Web that they use to access SaaS,
Web, and Windows applications, with the same single sign-on
convenience.
14 VMware, Inc.
Chapter 1 Introduction to View
End users can access the Workspace user portal on the Web from inside
n
a remote desktop for applications they need.
If you also use HTML Access, end users can open a remote desktop
n
inside a browser, without having to install any client application on the
client system or device.
IT managers can use the Workspace Administrator Web interface to
n
monitor user and group entitlements to remote desktops.
VMware Mirage
You can use Mirage to deploy and update applications on dedicated fullclone remote desktops without overwriting user-installed applications or
data. Mirage also periodically backs up the desktop so that if necessary, users
can recover partial or full desktops.
Mirage provides a better offline virtual desktop solution than the Local Mode
feature that was previously included with View. Mirage includes the
following security and management features for offline desktops:
Encrypts the locally installed virtual machine and prevents a user from
n
modifying virtual machine settings that affect the integrity of the secure
container.
Provides policies, including expiration, available in VMware Fusion™
n
Professional and VMware® Player Plus™, that are comparable to the
polices provided with the previous Local Mode feature. Fusion Pro and
Player Plus are included with Mirage.
Eliminates the need for users to check in or check out their desktops to
n
receive updates.
Enables administrators to utilize the Mirage layering capability, backup
n
features, and file portal.
Integrating with Popular Video Conferencing Software
Flash URL Redirection
Streaming Flash content directly from Adobe Media Server to client
endpoints lowers the load on the datacenter ESXi host, removes the extra
routing through the datacenter, and reduces the bandwidth required to
simultaneously stream live video events to multiple client endpoints.
The Flash URL redirection feature uses a JavaScript that is embedded inside
a Web page by the Web page administrator. Whenever a virtual desktop user
clicks on the designated URL link from within a Web page, the JavaScript
intercepts and redirects the ShockWave File (SWF) from the virtual desktop
session to the client endpoint. The endpoint then opens a local VMware Flash
Projector outside of the virtual desktop session and plays the media stream
locally.
NOTE With Flash URL Redirection, the multicast or unicast stream is
redirected to client devices that might be outside your organization's
firewall. Your clients must have access to the Adobe Web server that hosts
the ShockWave Flash (SWF) file that initiates the multicast or unicast
streaming. If needed, configure your firewall to open the appropriate ports to
allow client devices to access this server.
VMware, Inc. 15
View Architecture Planning
This feature is available only on some types of clients. To find out whether
this feature is supported on a particular type of client, see the feature support
matrix included in the "Using VMware Horizon Client" document for the
specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Microsoft Lync
You can use a Microsoft Lync 2013 client on remote desktops to participate in
Unified Communications (UC) VoIP (voice over IP) and video chat calls with
Lync certified USB audio and video devices. A dedicated IP phone is no
longer required.
This architecture requires the installation of a Microsoft Lync 2013 client on
the remote desktop and a Microsoft Lync VDI plug-in on the Windows 7 or 8
client endpoint. Customers can use the Microsoft Lync 2013 client for
presence, instant messaging, Web conferencing, and Microsoft Office
functionality.
Whenever a Lync VoIP or video chat call occurs, the Lync VDI plug-in
offloads all the media processing from the datacenter server to the client
endpoint, and encodes all media into Lync-optimized audio and video
codecs. This optimized architecture is highly scalable, results in lower
network bandwidth used, and provides point-to-point media delivery with
support for high-quality real-time VoIP and video. For more information, see
the End User Computing Blog entry at
http://blogs.vmware.com/euc/2013/06/the-abcs-of-deploying-vmwarehorizon-view-5-2-with-microsoft-lync-2013.html.
NOTE Recording audio is not yet supported. This integration is supported
only with the PCoIP display protocol.
Integrating View with Business Intelligence Software
You can configure View Connection Server to record events to a Microsoft SQL Server or Oracle database.
End-user actions such as logging in and starting a desktop session.
n
Administrator actions such as adding entitlements and creating desktop pools.
n
Alerts that report system failures and errors.
n
Statistical sampling such as recording the maximum number of users over a 24-hour period.
n
You can use business intelligence reporting engines such as Crystal Reports, IBM Cognos, MicroStrategy 9,
and Oracle Enterprise Performance Management System to access and analyze the event database.
For more information, see the View Integration document.
You can alternatively generate View events in Syslog format so that the event data can be accessible to
analytics software. If you enable file-based logging of events, events are accumulated in a local log file. If
you specify a file share, the log files are moved to that share. For more information, see the View Installation
document.
Using View PowerCLI to Create Administration Scripts
Windows PowerShell is a command-line and scripting environment that is designed for Microsoft
Windows. PowerShell uses the .NET object model and provides administrators with management and
automation capabilities. As with any other console environment, you work with PowerShell by running
commands, which are called cmdlets in PowerShell.
16 VMware, Inc.
Chapter 1 Introduction to View
The View PowerCLI provides an easy-to-use PowerShell interface to View. You can use the View PowerCLI
cmdlets to perform various administration tasks on View components.
Create and update desktop pools.
n
Configure multiple network labels to greatly expand the number of IP addresses assigned to virtual
n
machines in a pool.
Add datacenter resources to a full virtual machine or linked-clone pool.
n
Perform rebalance, refresh, or recompose operations on linked-clone desktops.
n
Sample the usage of specific desktops or desktop pools over time.
n
Query the event database.
n
Query the state of services.
n
You can use the cmdlets in conjunction with the vSphere PowerCLI cmdlets, which provide an
administrative interface to the VMware vSphere product.
For more information, see the View Integration document.
Modifying LDAP Configuration Data in View
When you use View Administrator to modify the configuration of View, the appropriate LDAP data in the
repository is updated. View Connection Server stores its configuration information in an LDAP compatible
repository. For example, if you add a desktop pool, View Connection Server stores information about users,
user groups, and entitlements in LDAP.
You can use VMware and Microsoft command-line tools to export and import LDAP configuration data in
LDAP Data Interchange Format (LDIF) files from and into View. These commands are for advanced
administrators who want to use scripts to update configuration data without using View Administrator or
View PowerCLI.
You can use LDIF files to perform a number of tasks.
Transfer configuration data between View Connection Server instances.
n
Define a large number of View objects, such as desktop pools, and add these to your View Connection
n
Server instances without using View Administrator or View PowerCLI.
Back up a configuration so that you can restore the state of a View Connection Server instance.
n
For more information, see the View Integration document.
Using SCOM to Monitor View Components
You can use Microsoft System Center Operations Manager (SCOM) to monitor the state and performance of
View components, including View Connection Server instances and security servers and the services
running on these hosts.
For more information, see the View Integration document.
Using the vdmadmin Command
You can use the vdmadmin command line interface to perform a variety of administration tasks on a View
Connection Server instance. You can use vdmadmin to perform administration tasks that are not possible from
within the View Administrator user interface or that need to run automatically from scripts.
For more information, see the View Administration document.

Planning a Rich User Experience 2
View provides the familiar, personalized desktop environment that end users expect. For example, on some
client systems, end users can access USB and other devices connected to their local computer, send
documents to any printer that their local computer can detect, authenticate with smart cards, and use
multiple display monitors.
View includes many features that you might want to make available to your end users. Before you decide
which features to use, you must understand the limitations and restrictions of each feature.

Horizon Client documentation at
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
20 VMware, Inc.
In addition, several VMware partners offer thin client devices for View deployments. The features that are
available for each thin client device are determined by the vendor and model and the configuration that an
enterprise chooses to use. For information about the vendors and models for thin client devices, see the Thin
Client Compatibility Guide, available on the VMware Web site.
Choosing a Display Protocol
A display protocol provides end users with a graphical interface to a remote desktop or application that
resides in the datacenter. Depending on which type of client device you have, you can choose between
PCoIP (PC-over-IP), which VMware provides, or Microsoft RDP (Remote Desktop Protocol).
You can set policies to control which protocol is used or to allow end users to choose the protocol when they
log in to a desktop.
NOTE For some types of clients, neither the PCoIP nor the RDP remote display protocol is used. For
example, if you use the HTML Access client, available with the HTML Access feature, the Blast protocol is
used, rather than PCoIP or RDP.
PCoIP
PCoIP (PC over IP) provides an optimized desktop experience for the delivery of a remote application or an
entire remote desktop environment, including applications, images, audio, and video content for a wide
range of users on the LAN or across the WAN. PCoIP can compensate for an increase in latency or a
reduction in bandwidth, to ensure that end users can remain productive regardless of network conditions.
Chapter 2 Planning a Rich User Experience
PCoIP is supported as the display protocol for remote applications and for remote desktops that use virtual
machines, physical machines that contain Teradici host cards, or shared session desktops on an RDS host.
PCoIP Features
Key features of PCoIP include the following:
Users outside the corporate firewall can use this protocol with your company's virtual private network
n
(VPN), or users can make secure, encrypted connections to a security server in the corporate DMZ.
Advanced Encryption Standard (AES) 128-bit encryption is supported and is turned on by default. You
n
can, however, change the encryption key cipher to AES-192 or AES-256.
Connections from all types of client devices.
n
Optimization controls for reducing bandwidth usage on the LAN and WAN.
n
32-bit color is supported for virtual displays.
n
ClearType fonts are supported.
n
Audio redirection with dynamic audio quality adjustment for LAN and WAN.
n
Real-Time Audio-Video for using webcams and microphones on some client types.
n
Copy and paste of text and, on some clients, images between the client operating system and a remote
n
application or desktop. For other client types, only copy and paste of plain text is supported. You
cannot copy and paste system objects such as folders and files between systems.
Multiple monitors are supported for some client types. For example, on Windows-based clients, you
n
can use up to four monitors and adjust the resolution for each monitor separately, with a resolution of
up to 2560 x 1600 per display. Pivot display and autofit are also supported.
When the 3D feature is enabled, up to 2 monitors are supported with a resolution of up to 1920 x 1200.
USB redirection is supported for some client types.
n
VMware, Inc. 21
View Architecture Planning
MMR redirection is supported for some Windows client operating systems and some remote desktop
n
operating systems (with View Agent-installed).

Recommended Guest Operating System Settings
Recommended operating system settings for remote desktops include the following settings:
For Windows XP desktops: 768MB RAM or more and a single CPU.
n
For Windows 7 or 8 desktops or Windows Server 2012 or R2 desktops: 1GB of RAM or more and a dual
n
CPU is recommended for playing in high-definition, full screen mode, or 720p or higher formatted
video. To use Virtual Dedicated Graphics Acceleration for graphics-intensive applications such as CAD
applications, 4GB of RAM is required.
Video Quality Requirements
480p-formatted video
720p-formatted video
1080p-formatted video
3D rendering
You can play video at 480p or lower at native resolutions when the remote
desktop has a single virtual CPU. If the operating system is Windows 7 or
later and you want to play the video in high-definition Flash or in full screen
mode, the desktop requires a dual virtual CPU. Even with a dual virtual
CPU desktop, as low as 360p-formatted video played in full screen mode can
lag behind audio, particularly on Windows clients.
You can play video at 720p at native resolutions if the remote desktop has a
dual virtual CPU. Performance might be affected if you play videos at 720p
in high definition or in full screen mode.
If the remote desktop has a dual virtual CPU, you can play 1080p formatted
video, although the media player might need to be adjusted to a smaller
window size.
You can configure remote desktops to use software- or hardware-accelerated
graphics. The software-accelerated graphics feature enables you to run
DirectX 9 and OpenGL 2.1 applications without requiring a physical graphics
processing unit (GPU). The hardware-accelerated graphics features enable
virtual machines to either share the physical GPUs (graphical processing
unit) on a vSphere host or dedicate a physical GPU to a single virtual
machine desktop.
For 3D applications, up to 2 monitors are supported, and the maximum
screen resolution is 1920 x 1200. The guest operating system on the remote
desktops must be Windows 7 or later.
For more information about 3D features, see “Using 3D Graphics
Applications,” on page 27.
Hardware Requirements for Client Systems
For information about processor and memory requirements, see the "Using VMware Horizon Client"
document for the specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.

Chapter 2 Planning a Rich User Experience
Microsoft RDP
Remote Desktop Protocol is the same multichannel protocol many people already use to access their work
computer from their home computer. Microsoft Remote Desktop Connection (RDC) uses RDP to transmit
data.
Microsoft RDP is a supported display protocol for remote desktops that use virtual machines, physical
machines, or shared session desktops on an RDS host. (Only the PCoIP display protocol is supported for
remote applications.) Microsoft RDP provides the following features:
With RDP 6, you can use multiple monitors in span mode. RDP 7 has true multiple monitor support, for
n
up to 16 monitors.
You can copy and paste text and system objects such as folders and files between the local system and
n
the remote desktop.
32-bit color is supported for virtual displays.
n
RDP supports 128-bit encryption.
n
Users outside the corporate firewall can use this protocol with your company's virtual private network
n
(VPN), or users can make secure, encrypted connections to a View security server in the corporate
DMZ.
NOTE For Windows XP desktop virtual machines, you must install the RDP patches listed in Microsoft
Knowledge Base (KB) articles 323497 and 884020. If you do not install the RDP patches, a Windows Sockets
failed error message might appear on the client.
Hardware Requirements for Client Systems
For information about processor and memory requirements, see the "Using VMware Horizon Client"
document for the specific type of client system. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
NOTE Mobile client devices use only the PCoIP display protocol.
Using Hosted Applications
You can use Horizon Client to securely access remote Windows-based applications, in addition to remote
desktops.
With this feature, after launching Horizon Client and logging in to a View server, users see all the remote
applications they are entitled to use, in addition to remote desktops. Selecting an application opens a
window for that application on the local client device, and the application looks and behaves as if it were
locally installed.
For example, on a Windows client computer, if you minimize the application window, an item for that
application remains in the Taskbar and looks identical to the way it would look if it were installed on the
local Windows computer. You can also create a shortcut for the application that will appear on your client
desktop, just like shortcuts for locally installed applications.
Deploying remote applications in this way might be preferable to deploying complete remote desktops
under the following conditions:
If an application is set up with a multi-tiered architecture, where the components work better if they are
n
located geographically near each other, using remote, hosted applications is a good solution.
VMware, Inc. 23
View Architecture Planning
For example, when a user must access a database remotely, if large amounts of data must be
transmitted over the WAN, performance is usually affected. With hosted applications, all parts of the
application can be located in the same data center as the database, so that traffic is isolated and only the
screen updates are sent across the WAN.
From a mobile device, accessing an individual application is easier than opening a remote Windows
n
desktop and then navigating to the application.
To use this feature, you install applications on a Microsoft RDS host. In this respect, View hosted
applications work similarly to other application remoting solutions. View hosted applications are delivered
using the PCoIP display protocol, for an optimized user experience.
Using View Persona Management to Retain User Data and Settings
You can use View Persona Management with remote desktops and with physical computers and virtual
machines that are not managed by View. View Persona Management retains changes that users make to
their profiles. User profiles comprise a variety of user-generated information.
User-specific data and desktop settings, which allow the desktop appearance to be the same regard less
n
of which desktop a user logs in to.
Application data and settings. For example, these settings allow applications to remember toolbar
n
positions and preferences.
Windows registry entries configured by user applications.
n
To facilitate these abilities, View Persona Management requires storage on a CIFS share equal or greater
than the size of the user's local profile.
Minimizing Logon and Logoff Times
View Persona Management minimizes the time it takes to log on to and off of desktops.
View takes recent changes in the profile on the remote desktop and copies them to the remote
n
repository at regular intervals. The default is every 10 minutes. In contrast, Windows roaming profiles
wait until logoff time and copy all changes to the server at logoff.
During logon, by default, View downloads only the files that Windows requires, such as user registry
n
files. Other files are copied to the remote desktop when the user or an application opens them from the
profile folder in the remote desktop.
You can configure View to download specified files when the user logs in and download other files in
the background.
With View Persona Management, during logoff, only files that were updated since the last replication
n
are copied to the remote repository.
With View Persona Management, you can avoid making any changes to Active Directory in order to have a
managed profile. To configure Persona Management, you specify a central repository, without changing the
user's properties in Active Directory. With this central repository, you can manage a user's profile in one
environment without affecting the physical machines that users might also log on to.
With View Persona Management, if you provision desktops with VMware ThinApp applications, the
ThinApp sandbox data can also be stored in the user profile. This data can roam with the user but does not
significantly affect logon times. This strategy provides better protection against data loss or corruption.
Configuration Options
You can configure View personas at several levels: a single remote desktop, a desktop pool, an OU, or all
remote desktops in your deployment. You can also use a standalone version of View Persona Management
on physical computers and virtual machines that are not managed by View.
24 VMware, Inc.
Chapter 2 Planning a Rich User Experience
By setting group policies (GPOs), you have granular control of the files and folders to include in a persona:
Specify whether to include the local settings folder. For Windows 7, Windows 8, and Windows Vista,
n
this policy affects the AppData\Local folder. For Windows XP, this policy affects the Local Settings
folder.
Specify which files and folders to load at login time. For example: Application
n
Data\Microsoft\Certificates. Within a folder, you can also specify files to exclude.
Specify which files and folders to download in the background after a user logs in to the desktop.
n
Within a folder, you can also specify files to exclude.
Specify which files and folders within a user's persona to manage with Windows roaming profiles
n
functionality instead of View Persona Management. Within a folder, you can also specify files to
exclude.
As with Windows roaming profiles, you can configure folder redirection. You can redirect the following
folders to a network share.
Contacts My Documents Save Games
Cookies My Music Searches
Desktop My Pictures Start Menu
Downloads My Videos Startup Items
Favorites Network Neighborhood Templates
History Printer Neighborhood Temporary Internet Files
Links Recent Items
To configure a remote repository to store personas, you can use either a network share or an existing Active
Directory user profile path that you configured for Windows roaming profiles. The network share can be a
folder on a server, a network-attached storage (NAS) device, or a network server. To support a large View
deployment, you can configure separate repositories for different desktop pools.
You can install a standalone version of View Persona Management on physical computers and virtual
machines that are not managed by View, allowing you to accomplish these goals:
Share and manage profiles across standalone systems and remote desktops.
n
Migrate user profiles from physical systems to remote desktops.
n
Perform a staged migration from physical systems to remote desktops.
n
Support up-to-date profiles when users go offline.
n
Limitations
View Persona Management has the following limitations and restrictions:
You must have a View license that includes the View Personal Management component.
n
View Persona Management requires a CIFS (Common Internet File System) share.
n
A user cannot access the same profile if the user switches between desktops that have v1 user profiles
n
and v2 user profiles. However, redirected folders can be shared between v1 and v2 profiles. Windows
XP uses v1 profiles. Windows Vista, Windows 7, and Windows 8 use v2 profiles.

Using USB Devices with Remote Desktops
Administrators can configure the ability to use USB devices, such as thumb flash drives, cameras, VoIP
(voice-over-IP) devices, and printers, from a remote desktop. This feature is called USB redirection, and it
supports using either the RDP or the PCoIP display protocol. A remote desktop can accommodate up to 32
USB devices.
When you use this feature, most USB devices that are attached to the local client system become available in
the remote desktop. You can even connect to and manage an iPad from a remote desktop. For example, you
can sync your iPad with iTunes installed in your remote desktop. On some client devices, such as Windows
and Mac OS X computers, the USB devices are listed in a menu in Horizon Client. You use the menu to
connect and disconnect the devices.
In most cases, you cannot use a USB device in your client system and in your remote desktop at the same
time. Only a few types of USB devices can be shared between the remote desktop and the local computer.
These devices include smart card readers and human interface devices such as keyboards and pointing
devices.
Administrators can specify which types of USB devices end users are allowed to connect to. For composite
devices that contain multiple types of devices, such as a video input device and a storage device, on some
client systems, administrators can split the device so that one device (for example, the video input device) is
allowed but the other device (for example, the storage device) is not.
The USB redirection feature is available in desktop pools that are deployed on single-user machines. The
feature is not available in RDS desktop pools.
NOTE The USB redirection feature is available only on some types of clients. To find out whether this
feature is supported on a particular type of client, see the feature support matrix included in the "Using
VMware Horizon Client" document for the specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Using the Real-Time Audio-Video Feature for Webcams and Microphones
With the Real-Time Audio-Video feature, you can use your local computer's webcam or microphone on
your remote desktop. Real-Time Audio-Video is compatible with standard conferencing applications and
browser-based video applications, and supports standard webcams, audio USB devices, and analog audio
input.
End users can run Skype, Webex, Google Hangouts, and other online conferencing applications on their
virtual desktops. This feature redirects video and audio data to the remote desktop with a significantly
lower bandwidth than can be achieved by using USB redirection. With Real-Time Audio-Video, webcam
images and audio input are encoded on the client and then sent to the remote desktop. On the remote
desktop the stream is decoded and played by a virtual webcam and virtual microphone, which can be used
by the third-party application.
No special configuration is necessary, although administrators can set GPOs and registry keys for the
remote desktop to configure frame rate and image resolution, or to turn the feature off altogether. By default
the resolution is 320 by 240 pixels at 15 frames per second. Administrators can also use client-side
configuration settings to set a preferred webcam or audio device if needed.
NOTE This feature is available only on some types of clients. To find out whether this feature is supported
on a particular type of client, see the feature support matrix included in the "Using VMware Horizon Client"
document for the specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.

Using 3D Graphics Applications
The software- and hardware-accelerated graphics features available with the PCoIP display protocol enable
remote desktop users to run 3D applications ranging from Google Earth to CAD and other graphicsintensive applications.
Chapter 2 Planning a Rich User Experience
Virtual Dedicated
Graphics Acceleration
(vDGA)
Virtual Shared Graphics
Acceleration (vSGA)
Soft 3D
For these features, up to 2 monitors are supported, and the maximum screen resolution is 1920 x 1200. The
guest operating system on the virtual machine desktops must be Windows 7 or later.
IMPORTANT For more information on the various choices and requirements for 3D rendering, see the
VMware white paper about graphics acceleration.
Available with vSphere 5.5 and later, this feature dedicates a single physical
GPU (graphical processing unit) on an ESXi host to a single virtual machine.
Use this feature if you require high-end, hardware-accelerated workstation
graphics.
Available with vSphere 5.1 and later, this feature allows multiple virtual
machines to share the physical GPUs on ESXi hosts. You can use 3D
applications for design, modeling, and multimedia.
Software-accelerated graphics, available with vSphere 5.0 and later, allows
you to run DirectX 9 and OpenGL 2.1 applications without requiring a
physical GPU. Use this feature for less demanding 3D applications such as
Windows Aero themes, Microsoft Office 2010, and Google Earth.
Streaming Multimedia to a Remote Desktop
The MMR (multimedia redirection) feature enables full-fidelity playback on Windows XP, Windows Vista,
Windows 7, and Windows 8 client computers when multimedia files are streamed to a remote desktop.
With MMR, the multimedia stream is processed, that is, decoded, on the Windows client system. The client
system plays the media content, thereby offloading the demand on the ESXi host.
For Windows XP and Windows Vista remote desktops, the MMR feature supports the media file
n
formats that the Windows XP or Windows Vista client system supports, because local decoders must
exist on the client. File formats include MPEG2, WMV, AVI, and WAV, among others.
For Windows 7 remote desktops and Windows 7 and 8 client systems, the MMR feature supports media
n
formats that comply with the H.264 video compression standard. The M4V, MP4, and MOV file formats
are supported.
IMPORTANT Windows 8 remote desktops do not support MMR. For these View agents, use Windows media
redirection, included with RDP 7 and later.
Because MMR is implemented differently on different operating systems, the system requirements for the
Windows 7 operating system are different from the requirements for Windows Vista and earlier operating
systems. For information about the system requirements for this feature, see "Using VMware Horizon Client
for Windows," available at https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
NOTE You must add the MMR port as an exception to your firewall software. The default port for MMR is
9427.

Printing from a Remote Desktop
The virtual printing feature allows end users on some client systems to use local or network printers from a
remote desktop without requiring that additional print drivers be installed in the remote desktop operating
system. The location-based printing feature allows you to map remote desktops to the printer that is closest
to the endpoint client device.
With virtual printing, after a printer is added on a local client computer, that printer is automatically added
to the list of available printers on the remote desktop. No further configuration is required. For each printer
available through this feature, you can set preferences for data compression, print quality, double-sided
printing, color, and so on. Users who have administrator privileges can still install printer drivers on the
remote desktop without creating a conflict with the virtual printing component.
To send print jobs to a USB printer, you can either use the USB redirection feature or use the virtual printing
feature.
Location-based printing allows IT organizations to map remote desktops to the printer that is closest to the
endpoint client device. For example, as a doctor moves from room to room in a hospital, each time the
doctor prints a document, the print job is sent to the nearest printer. Using this feature does require that the
correct printer drivers be installed in the remote desktop.
NOTE These printing features are available only on some types of clients. To find out whether a printing
feature is supported on a particular type of client, see the feature support matrix included in the "Using
VMware Horizon Client" document for the specific type of desktop or mobile client device. Go to
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
Using Single Sign-On for Logging In to a Remote Desktop
The single-sign-on (SSO) feature allows end users to supply login credentials only once.
If you do not use the single-sign-on feature, end users must log in twice. They are first prompted to log in to
View Connection Server and then are prompted log in to their remote desktop. If smart cards are also used,
end users must sign in three times because users must also log in when the smart card reader prompts them
for a PIN.
For remote desktops, this feature includes the Graphical Identification and Authentication (GINA) dynamiclink library for Windows XP and a credential provider dynamic-link library for Windows Vista, Windows 7,
and Windows 8.
Using Multiple Monitors
Regardless of the display protocol, you can use multiple monitors with a remote desktop.
If you use PCoIP, the display protocol from VMware, you can adjust the display resolution and rotation
separately for each monitor. PCoIP allows a true multiple-monitor session rather than a span mode session.
A span mode remote session is actually a single-monitor session. The monitors must be the same size and
resolution, and the monitor layout must fit within a bounding box. If you maximize an application window,
the window spans across all monitors. Microsoft RDP 6 uses span mode.
In a true multiple-monitor session, monitors can have different resolutions and sizes, and a monitor can be
pivoted. If you maximize an application window, the window expands to the full screen of only the monitor
that contains it.
28 VMware, Inc.
Chapter 2 Planning a Rich User Experience
This feature has the following limitations:
If you use PCoIP, the maximum number of monitors that you can use to display a remote desktop is 4,
n
with a resolution of up to 2560 X 1600 if you have enough video RAM. The maximum number of
monitors that can be stacked vertically is 2. If you use more than 2 monitors, the monitors must be in
the same mode and have the same screen resolution. That is, if you use 3 monitors, all 3 monitors must
be in either portrait mode or landscape mode and must use the same screen resolution.
To use the 3D rendering feature, you can use up to 2 monitors, with a resolution of up to 1920 X 1200.
n
You must use the PCoIP display protocol.
If you use Microsoft RDP 7, the maximum number of monitors that you can use to display a remote
n
desktop is 16.
If you use Microsoft RDP display protocol, you must have Microsoft Remote Desktop Connection
n
(RDC) 6.0 or higher installed in the remote desktop.
