"IntelliCache is one feature of XenServer that caches temporary and non-persistent files for desktop workloads on the local disk of the host server. "

This way you can reduce centralized storage space

IntelliCache makes hosted Virtual Desktop Infrastructure deployments more cost-effective by enabling you to use a combination of shared storage and local storage. It is of particular benefit when many Virtual Machines (VMs) all share a common OS image.

Prior to XenServer IntelliCache, the best way considered to manage the storage for XenDesktop was to keep the base XenDesktop image (VHD) on NAS. The issue with this setup is that during initial storming VM boot up from that image (that is many VMs booting up simultaneously thus storming the environment) this causes a lot of load on the NAS.

The other way considered was to manually copy the VHD for every VM to its host (whether the XenServer, ESXi, Hyper-V etc...). This causes an overhead of maintaining and syncing changes between the NAS and host which turned out to be impractical and very complex.

This is when intellicache came into picture. A master VHD/image file is built and saved on the NAS. The VMs boot from it and the XenServer will intelligently cache these images thus automating the cache and isolating the NAS from load issues which in turn means better performance.

Windows Server 2003 introduced persistent Volume Shadow Copies and made 2003 a must-do upgrade.  Since then, it's been a must-implement feature for all servers doing any kind of file sharing.
