Hard Disk Drive
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 as well as the hard disk drive.
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.
Bays can contain up to 8 hard disk drives.
Unique slot numbers have been assigned to each slot.
