Recovering from Server Hardware Failure

Recovering from disasters isn't limited to being able to restart the server or restore deleted files. Anyone who's ever had hard disks fail and lost important data can testify to the importance of a computer's capability to recover from hardware failure. Similarly, if a server becomes unavailable due to a major problem, network users are unable to access resources. To deal with the possibility of hardware failure,Windows Server 2003 natively supports different methods of recovery, including the use of fault-tolerant disks and server clustering.

The Role of Fault-Tolerant Disks

Fault-tolerant disks enable a computer to recover from a disaster, so that data won't be lost or corrupted. RAID (Redundant Array of Independent - or Inexpensive - Disks ) provides several methods of writing data across multiple disks. If one disk in an array fails, RAID enables you to replace the damaged disk and recover the data quickly. There are many different levels of RAID available, both as hardware and as software implementations. Windows Server 2003 supports only two built-in software implementations of RAID: RAID 1 and RAID 5.
