Disk partitioning, RAID configuration, and failover

The four hard drives included in the 1500s are configured for
hardware RAID fault tolerance using the Adaptec 2410SA SATA
RAID Controller.
The Primary OS Logical Drive is configured as a 9GB RAID
1 mirror spanning drives 0 and 1.
The Secondary OS Logical Drive is configured as a 9GB
RAID 1 mirror spanning drives 2 and 3.
The Data volume is configured as a RAID 5 volume spanning the
remaining space across all four drives. The BIOS supports a boot
failover mechanism that will allow the system to automatically
boot to the next drive if a failure occurs on the previously booted
hard drive.
