Upgrading Your Server 9-77
3.5-inch Disk Model
You can build a RAID System by using the Onboard RAID Controller (LSI Embedded MegaRAID) or an optional RAID
Controller (LSI Logic SAS CTRL 8708EM2).
Onboard RAID Controller (LSI Embedded MegaRAID)
If the setting of the RAID configuration jumper on the mother board is changed, the internal hard disk drives can be detected as
RAID hard disk drives. See the figure below.
Optional RAID Controller (LSI Logic SAS CTRL 8708EM)
Your server can include the optional RAID Controller LSI Logic SAS CTRL 8708EM. The optional RAID Controller can
control the internal hard disk drives as the RAID System. To use the hard disk drives in a RAID System, reconnect the hard
disk drive interface cable on the mother board.
At the factory, the interface cable is connected to the SATA HDD connector on the mother board. Refer to the manual coming
with the optional RAID Controller LSI Logic SAS CTRL 8708EM for details.
IMPORTANT: The RAID Controller board is extremely sensitive to static electricity. Make sure
to touch the metal frame of the Server to discharge static electricity from your body before
handling the RAID Controller. Do not touch the RAID Controller terminals or on-board parts by a
bare hand or place the RAID Controller directly on the desk. For static notes, see the section
"Anti-static Measures" described earlier.
NOTE: Before installing an optional RAID Controller, run the SETUP utility, select [Advanced]
→ [PCI Configuration], and confirm that [Enabled] is set for the parameter [PCI Slot xx ROM]
(xx: PCI slot number).
