Storage is a big bottleneck in regards to desktop virtualization. High speed centralized storage (SAN) is expensive, but eases complexity. Local storage is cheap and fast, but increases complexity. The ideal solution would be a marriage of cheaper centralized storage (NAS) with local storage for eased complexity and fast desktop performance. This is the goal of Citrix’s IntelliCache feature. IntelliCache basically uses centralized storage to store desktop image and caches the image on the local storage of the XenServer. Subsequent requests for the image will be retrieved from local storage instead of traversing the LAN. IntelliCache will be part of XenServer 5.6 SP1.
