RAID Array Organization
The system logical drives are default configured as Redundant Arrays of Independent Disks
(RAID). the RAID methodology and technique used varies with the function of the
logical drive. The RAID techniques used in each logical drive are:
Base Unit Drive C:\ - System O/S:
n Factory configured
n A first RAID 1 striped across a partition on three drives with a second RAID 1 striped
across another partition on three different drives.
n The two RAID 1 arrays above are combined into a RAID 0 mirrored array.
n This array cannot be changed without damaging the O/S image.
