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 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
