RAID overview
Redundant Array of Independent Disks (RAID) is a technology that can combine two or more
drives for fault tolerance and continued system performance. The Avaya CallPilot RAID
controller is a PCI RAID SCSI card that provides high-performance disk mirroring. CallPilot
uses RAID Level 1.
With Level 1 mirroring, two equal-capacity disk drives mirror one another. One disk drive serves
as the backup copy of the other disk drive. If one disk drive fails, the other continues to run.
RAID configuring and splitting
Working with RAID involves the following:
• Verifying the RAID firmware version
• Upgrading or downgrading the RAID firmware
• Configuring RAID using the LSI Elite 1600 controller and the Ctrl+M menu at server boot-
up
