Hardware redundant array of independent disks (RAID)

The Windows Catalog contains many different hardware RAID configurations for clusters. Because many hardware RAID solutions provide power, bus, and cable redundancy within a single cabinet, and track the state of each component in the hardware RAID firmware, they provide data availability with multiple redundancy, protecting against multiple points of failure. Hardware RAID solutions can also use an on-board processor and cache.

Windows Server 2003, Enterprise Edition and Windows Server 2003, Datacenter Edition can use these disks as standard disk resources.

For more information on the different hardware RAID configurations, see the Microsoft Windows Catalog at Support resources.


  • You cannot use software fault-tolerant disk sets for cluster storage.
