Understanding creating basic disk groups

When you group one or more physical drives together and configure the controller to access them in a particular pattern, you create a basic disk group. The maximum number of basic disk groups depends on the controller and RAID level.

Disk groups are used to improve security, performance, and reliability. The amount of improvement depends on the application programs that you run on the %SERVER%, controller parameters, and the RAID levels that you assign to the logical devices in your disk groups.
