•
Use SAS/SATA Hard Disk Drives or SSDs that have the same capacity and rotational speed.
•
If you intend to install the OS to the RAID System, the process from RAID configuration to OS installation
can be easily completed by using the EXPRESSBUILDER. If you wish to install the OS manually, use a
RAID System Configuration utility (WebBIOS or SuperBuild utility). The utility can be run during POST
which starts immediately after the server is turned on. For details on the procedure of configuring a Logical
Drive, refer to Chapter 2 (4. RAID System Configuration) in "Maintenance Guide" or the manual supplied
with the optional RAID Controller (N8103-172/173/174/168).
