#Citrix #XenApp 6.5 Hosted Shared Desktop Sizing Example

Great Citrix blog post series from Andy Baker!

In this blog series I’m taking a look at scalability considerations for XenApp 6.5 Hosted Shared Desktops, specifically:

  1. How to estimate XenApp 6.5 Hosted Shared Desktop scalability
  2. What’s the optimal XenApp 6.5 VM specification?
  3. XenApp 6.5 Hosted Shared Desktop sizing example

My last post provided guidance on the optimal XenApp virtual machine specification.  Now in the last post of the series, I’m going to walk through an example sizing exercise.

Scenario

Company ABC recently completed a user segmentation exercise.  The following table includes 8 user groups that have been identified as good candidates for a Hosted Shared Desktop.  None of these user groups requires the ability to install applications or the ability to customize their desktop beyond profile based changes.  Three separate Provisioning Services images will be created due to application compatibility conflicts identified by Citrix AppDNA.

With Hosted Shared Desktops, it is important to consider the ‘Maximum Number of Concurrent Users’ column rather than the ‘Total Number of Users’ column.  Sizing the environment for concurrency rather than the total number of users will help to reduce infrastructure costs without affecting performance or availability.

Sufficient redundancy should be incorporated into the sizing estimate so that a single XenApp server or virtualization host failure does not affect the total number of concurrent users that can be supported (n+1).

Company ABC wishes to use their standard hardware specification…
