7.2 Citrix XenDesktop with XenApp Hosted Shared Test Results
Customers are looking to virtualize XenApp implementations for a combination of reasons, some which include
the flexibility to consolidate under-utilized XenApp servers, application or desktop silos, business continuity
planning, etc. So when looking to virtualize XenApp for Hosted Shared desktops, it is important to assess the best
virtual machine configurations for optimal performance. Unlike the multi-chassis configuration of the Hosted VDI
testing, the main objective for the testing was to obtain an optimal virtualized configuration for multiple XenApp
virtual machines on a single blade. This means finding an optimal balance between number of virtual machines
and number of vCPUs per virtual machine while successfully supporting the maximum number of user sessions.
The following configurations were tested as part of this effort and the Total Number of User Sessions achieved for
each virtual machine is highlighted:
