The goals of this document are to provide storage sizing guidance and best practices based on lab results for a Citrix XenDesktop based VDI solution.

Our test infrastructure included:

• Citrix XenDesktop 5.0
• VMware® vSphere™ 4.1 Hypervisor™
• Dell PowerEdge™ M610 blade servers
• Dell PowerConnect™ switches
• Dell EqualLogic™ SANs

The primary objectives of our testing were:

• Determine how many virtual desktops can be deployed using a single Dell EqualLogic PS6010XVS virtualized iSCSI SAN array with acceptable user experience indicators for task workers.
• Determine the performance impact on the storage array during peak I/O activity such as boot and login storms.
• Determine how to scale the number of virtual desktops by adding additional storage array members.
