BP1018 Sizing and Best Practices for Citrix XenDesktop with Dell EqualLogic Storage 5
Figure 1 Citrix XenDesktop core infrastructure components
Overview of the core infrastructure components (see Figure 1):
• We used two provisioning servers (PVS) and two Desktop Delivery Controllers (DDC) for
streaming the master disk image to virtual desktops. Two servers were used for high availability
and better performance.
• PVS and DDC servers were virtualized and hosted on two separate ESXi servers for high
availability.
