Configuring your onboard RAID solution
Your server comes equipped with an onboard chipset for a SATA RAID solution, which
supports RAID levels 0 (striping), 1 (mirroring), 5 (distributed data and parity), and 10
(RAID 0 + 1). You enable the onboard RAID solution in the BIOS (See SATA -
page 98
) and
configured by launching the appropriate RAID BIOS console during the boot process.
