2.5-inch Hard Disk Drive
Up to 8 hard disk drives mounted on the 2.5-inch width dedicated tray can be installed on the 2.5-inch hard disk
drive bay located at the front of the unit.
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
representative for hard disk drives optimum for your server.
The operation is run on the created mirror volume with installed hard disk drive pairs such as slot 0 on CPU/IO
module 0/1, slot 1 on CPU/IO module 0/1, slot 2 on CPU/IO module 0/1. The OS is installed on the mirror
volumes that consist of the hard disks in the slot 0.
Slots related to the mirroring process
Empty slots in the 2.5-inch hard disk drive bay contain dummy trays. The dummy trays are inserted to improve
the cooling effect in the server. Always insert the dummy trays in the slots with no hard disks drive installed.
