Dell Virtual Remote Desktop Solution Reference Architecture 9

General Guidelines

The following guidelines are valid for all four validated configurations:

•

CPUs

: Dell recommends quad core CPUs for XenDesktop deployments,

as CPU performance is typically the limiting factor in the number of

virtual desktops that can be deployed.

•

XenServer Configuration:

Due to rack space density, rack-mount

dual-socket servers are typically best for XenDesktop deployments.

•

XenMotion:

XenMotion allows the seamless migration of a virtual

machine from one XenServer to another. This requires that shared storage

is available in either iSCSI or SAN types. This migration functionality has

been tested on both a Dell MD3000i and Equalogix PS-5000X.

Depending on the XenDesktop package you purchased, XenMotion may

be included with XenServer. If XenMotion is part of the package, Dell

recommends that you implement the application. A shared storage unit is

required to support this functionality: both iSCSI and SAN are supported.

•

RAID Configuration:

RAID 1 is recommended for the XenServer boot

volume. For best performance and reliability, Dell recommends RAID 10

for local VM storage.

•

Citrix Provisioning Server:

Citrix Provisioning Server streams the OS to

each VM, resulting in a large savings in storage and simplified image

management.
