BP1018 Sizing and Best Practices for Citrix XenDesktop with Dell EqualLogic Storage 9
Figure 3 Virtual desktop disk composition in Citrix XenDesktop VDI environment
As shown in Figure 3, the shared read-only vDisk and temporary write cache are served from
EqualLogic PS6010XVS array(s). The user data is kept separate by using a separate CIFS share.
3.4 EqualLogic storage array configuration
We used a single EqualLogic PS6010XVS array to store the vDisk of the PVS and also the write cache
for all virtual desktops. Only 2.1 TB on the array was used to configure virtual desktops which resulted
in more than 15% head room on the storage array.
The volume layout used for configuring vDisk and write cache on a single PS6010XVS array is shown in
Table 2.
