You can enable the intelliicache function:

① The local host caches XenDesktop Images
② Reduce the total cost of storage ownership
③ Reduce IOPS on shared storage
④ Cost-effective) shared storage space required for WriteCache,

This function is available only in XenDesktop5SP1 and XenServer5.6SP2.

To create a Directory Pool in MCS, follow these steps:

① Select a VDA template. For example, the template size is 7 GB.

② Automatic creation of the master snapshot). If there is a snapshot, select [in step ①, this step will not be done. Time: seconds.

③ Automatic copying of snapshots to the target storage ). For several minutes ).

④ Create a DIFF disk and an ID disk automatically on the target storage ). Playback time: seconds depending on the VM Size ).

Enable the intelliicache function:

Create a basic disk BaseDisk from the primary disk through the MCS of XenDesktop), create a DIFF disk on the local storage, and create an ID disk IDENT disk on the shared storage ). The Virtual Machine is configured to use a basic disk and started with a virtual machine of the basic disk. XenServer first reads the cached object DIFF from the local storage, then the Virtual Machine reads from the local cache, and other reads need to be read from the shared storage, then start.

Pool random) mode and streaming mode of the virtual machine is (on-boot = reset) Restart] This mode will delete the DIFF disk when the virtual machine is shut down], this mode is generally doesnotallow is not allowed) Enable XenMotion.

Pool static) mode, and the virtual machine in proprietary mode is on-boot = persist) logout. In this mode, the DIFF disk is deleted when the virtual machine is shut down. livemigrationispossible can enable XenMotion ).
Note: Additional virtual machines will use the same read Cache
