For a heavily used volume, you can improve disk response time by distributing volume segments across multiple disks (disk striping). This configuration option is called Redundant Array of Inexpensive Devices (RAID). For background information and instructions, see Creating a RAID Device in the Novell Storage Services Administration Guide.
If one of the disks fails, the entire volume becomes unavailable. Therefore, you should mirror or duplex drives containing spanned volumes.
If a disk containing a spanned volume fails, the entire volume must be restored from a backup across all segments before you can use it again.
The most effective way to distribute volume segments is to do so equally across the disks. Do not simply fill up a disk, add another, add another, etc.
