Citrix Provisioning Server – Impact of System Cache on SAN I/O

I was recently involved in a project to improve performance in a XenDesktop 4 / Provisioning Server 5.6 environment where users were reporting slow logon times and sluggish performance, and SAN statistics showed higher IOPS than we would have liked. The environment consists of two Desktop Delivery Controllers (DDCs) on Windows 2003 R2 and two Read more…
