Intel Turbo Memory (ITM) is an integrated nonvolatile (NV) caching solution. ITM works together with Microsoft RAID, and it introduces support for caching of a RAID device. This NV caching solution requires that NV cache commands be sent to the RAID device. In Windows Vista, the NV cache commands can be sent only to HDC-class devices. However, many RAID products are Small Computer Standard Interface (SCSI)-class devices. Therefore, the NV cache commands cannot be sent to these devices, reports Microsoft.
