Reference Architecture

16 Dell Virtual Remote Desktop Solution Reference Architecture
Building Blocks for Large Configurations
The components of Large Configurations are:
• Servers: Dell recommends 1U and 2U servers for space and performance
reasons. Rack space, expected performance, future expansion, and
power/cooling capacity are key factors in selecting the server form factor.
Network connections on XenServer servers use both of the embedded
NICs—typically one for the virtual machines and one for storage and
infrastructure connections. A dual port add-in NIC is expected if iSCSI
storage is used for XenMotion.
NOTE: The tower server can be rack mounted as a 5U rack server.
• CPU: Quad core CPUs are recommended in all XenDesktop solutions for
maximum virtual desktop scalability.
•
Memory: The minimum amount of memory required is 16 GB RAM,
which can be expanded up to 64 GB if more memory per VM is needed.
