9.2. Windows NT and RAID Implementation

One obvious way to have RAID with Windows NT is for RAID to be implemented in hardware, such as in the HBA or the storage device controller.

Several drivers in the Windows Server family implement (host-based) RAID, including the fault-tolerant FtDisk driver, the Logical Disk Manager (LDM) driver that ships with Windows 2000, and the VERITAS Logical Volume Manager (LVM) product available for Windows 2000 from VERITAS.
