![]() The cache on local HD is stored in a file called. The local HD must contain a basic volume pre-formatted with a Windows NTFS file system with at least 512MB of free space.Local HD in every device using the vDisk.PVS does not redirect the page file in the case of RAM cache. The PVS target software will, by default, redirect the system page file to the same disk as the write cache so that the pagefile.sys is allocating space on the cache drive unless it is manually set up to be redirected on a separate volume.įor RAM cache without a local disk, you should consider setting the system page file to zero because all writes, including system page file writes, will go to the RAM cache unless redirected manually. As a result, it will fail over to Cache on the server. If the PVS target is using Cache on Device RAM with overflow on hard disk or Cache on device hard disk, the PVS target software either does not find an appropriate hard disk partition or it is not formatted using NTFS. When a target device boots to a vDisk in standard mode/shared mode, regardless of the cache type, the data written to the Write Cache is deleted on boot so that when a target is rebooted or starts up it has a clean cache and contains nothing from the previous sessions. When the target device is booted in standard mode or shared mode, the write cache information is checked to determine the cache location. When the vDisk mode is private/maintenance mode, all data is written back to the vDisk file on the PVS Server. Cache on device RAM with overflow on hard disk.Instead, it is written to a write cache file in one of the following locations: If data is written to the PVS server vDisk in a caching mode, the data is not written back to the base vDisk. ![]() The write cache includes data written by the target device. In PVS, the term “write cache” is used to describe all the cache modes. Write Cache in Provisioning Services Server This article provides information about write cache usage in a Citrix Provisioning, formerly Provisioning Services (PVS), Server.
