Deleting cache on a difference disk
The Delete Cache from Selected Device(s) context menu option allows you to manually delete cache on a difference disk. The option is only available if the vDisk cache mode is set to Server Persistent Cache.
Write cache on a Difference Disk is not automatically deleted if that file becomes invalid. Files marked as invalid should periodically be deleted manually.
