Disk array configuration of internal hard disk drives
Observe the following notes on configuring a disk array:
– The server must contain more than one SCSI or SAS hard disk drive having the same
capacity and the same rotational speed. (The minimum number of required disks
depends on the configuration of RAID (Redundant Arrays of Inexpensive
[Independent] Disks).)
– Select/set a RAID level "RAID0", "RAID1", or "RAID5" of disk array configuration.
When installing a system in an internal hard disk drive, you should use "Express Setup" to
perform all the procedures for RAID configuration, OS installation, and then OS setup.
Use Express Setup even when not installing a system. Start Express Setup, select [OS
Selection] → [Others]. The installer automatically performs all the procedures for RAID
configuration, maintenance partition setting, and then maintenance utility installation.
When making the setup in manual mode, use the RAID configuration utility in the chip on
the board. You can start the utility during execution of POST that automatically starts
immediately after you turn on the server power switch. For details, see the online
document in the NEC EXPRESSBUILDER CD-ROM provided with the server. (The
utility varies depending on the disk array controller board.) For details on the data transfer
rate, RAID, and array configuration, see the manual provided with the disk array
controller board as well as the online document.
