Lesson 3	Implement fault-tolerant volumes.
Objective	Overview and implementation of fault-tolerant volumes

Overview Implementation fault-tolerant Volumes

Microsoft Windows 2000 Server supports two types of fault-tolerant volumes: mirrored volumes and RAID-5 volumes. Similar to mirror sets and stripe sets with parity in Windows NT Server version 4.0, Windows 2000 fault-tolerant volumes write the same data on multiple disks. Understanding how to use fault-tolerant volumes helps you to protect data against potential disk failures.

Mirrored or RAID-5 volume

You must have unallocated space on at least two dynamic disks to create a mirrored volume, and unallocated space on at least three dynamic disks to create a RAID-5 volume. The following Slide Show illustrates how to create a mirrored or RAID-5 volume from unallocated space.

To mirror an existing volume, perform the following steps:

Right-click the volume that you want to mirror, and then click Add Mirror.
Select the second disk in the mirrored volume, and then click OK

The next lesson shows you how to recover a failed mirror volume.
