Hard Disk Drive
Expansion Bays for hard disk drives are provided at the front of the server.
A hard disk drive mounted in a dedicated drive tray can be purchased. Install the hard disk drive on the
server with it mounted in the drive tray.
Important Use hard disk drives specified by NEC. Installing a third-party hard disk
drive might cause a failure of the server and it.
Note the following precautions to install hard disk drives.
For onboard connection, hard disk drives having different capacities, types, or rotational speeds cannot
be installed together.
In the RAID System, all the hard disk drives in a group (pack) must have the same capacity, type, and
rotational speed.
If using hard disk drives in a RAID System, jumper settings or a change of cables may be required.
Bays can accommodate up to 8 hard disk drives.
