Introduction to RAID : RAID Configuration Strategies

RAID Configuration Strategies

The following factors in RAID drive group configuration are most important:

*

Virtual drive availability (fault tolerance)

*

Virtual drive performance

*

Virtual drive capacity

You cannot configure a virtual drive that optimizes all three factors, but it is easy to choose a virtual drive configuration that maximizes one factor at the expense of another factor. For example, RAID 1 (mirroring) provides excellent fault tolerance, but requires a redundant drive.

The following subsections describe how to use the RAID levels to maximize virtual drive availability (fault tolerance), virtual drive performance, and virtual drive capacity.
