Dell Virtual Remote Desktop Solution Reference Architecture 11

The components of Very Small Configurations are:

•

Servers:

Because this configuration is intended for a proof-of-concept

deployment or a deployment to a small office/satellite office, non-rack

mounted servers are available. The Active Directory and License Server

roles are combined on one server. Any server on the XenServer

compatibility matrix (located in the XenServer Reference Architecture)

can be used in place of the XenServer servers.

•

CPU:

Quad core CPUs are recommended in all XenDesktop solutions

for maximum virtual desktop scalability.

•

Memory:

16 GB RAM provides enough memory to deploy many

virtual desktops.

•

Network:

The two onboard gigabit NICs provide enough bandwidth to

support network traffic. The service console and management are shared

on the same NIC. With the exception of the client network (which only

requires 10 Mbit for each client), Dell recommends gigabit network

switches throughout the solution.

•

Disk:

Local storage is used on the XenServer systems to store the

VM configuration only. The virtual machine disk images are stored on

the Provisioning Server.

Small Configuration

The Small Configuration is designed to be a simple configuration of five to

eight servers—each running XenServer—that supports up to 256 knowledge

worker desktop loads. The minimum memory Dell recommends in this

configuration is 16 GB per server. The storage requirements are expected to

be low, and local storage may be suitable for some deployments.

Two Provisioning servers are used in this configuration, along with a

Dell FE600W failover cluster. This provides redundant and scalable

streaming server capabilities, and vastly decreases the storage requirements

needed. Shared storage such as a Dell|Equalogix™ PS5000XV will also allow

the use of XenMotion to help load balance the XenServer workload. Storage

options for Provisioning Server are addressed by the Provisioning Server

Deployment Guide and Reference Architecture Guide.
