SCA2 interface are installed.
IMPORTANT:
„
Do not use any hard disks that are not authorized by NEC. Installing a third-party hard disk may
cause a failure of the server as well as the hard disk. Purchase hard disks of the same model in
pair. Contact your sales agent for hard disk drives optimum for your server.

The 320Fb-MR model is used in the example quoted here. However steps you should take are the same
for other models. You can install 25.4mm (1-inch) high hard disk drives to six 3.5-inch hard disk drive
bays on the server. 3.5-imch hard disk drive bays have labels with slot number.
The hard disk drives installed on the slot 0, 1 and 2 are mirrored with the slot 3, 4, and 5 respectively.
(The OS is installed on the mirror volumes that consist of the hard disks in the slot 0 and 3)
Empty slots in the 3.5-inch hard disk drive bay contain dummy trays. The dummy trays are inserted to
improve the cooling effect within the device. Always insert the dummy trays in the slots in which hard
disks are not installed.
Attach an HDD ID label indicating the slot number of installed hard disk to the handle of the hard disk.
