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. All of these drivers were discussed in Chapter 1 and also in Chapter 6. The RAID support provided by these pieces of software is summarized in Table 9.1.

Table 9.1. RAID Capabilities of Several Windows Volume Managers

RAID Level	FtDisk	Windows 2000 Logical Disk Manager	VERITAS Logical Volume Manager
RAID 0	Yes	Yes	Yes
RAID 1	Yes	Yes	Yes
RAID 5	Yes	Yes	Yes
RAID 10	No	No	Yes
