9-80 Upgrading Your Server
Notice
Observe the following notes on configuring a RAID System:
 The installed hard disk drives (SAS drives or SATA drives) must have 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", "RAID5", or "RAID6".
IMPORTANT: To use RAID5, RAID50, or RAID6, RAID KEY FOR SAS CTRL 8708EM2 is
required.
When installing an operating system on an internal hard disk drive, you should use "Express Setup" to perform all the
procedures for RAID System configuration, OS installation, and then OS setup.
Use Express Setup even when not installing an operating system. Start Express Setup, select [OS Selection] → [Others]. The
installer automatically performs all the procedures for RAID System configuration, and then installs maintenance utility.
When configuring manually, use the RAID System configuration utility of the onboard controller. You can start the utility
during POST that automatically starts immediately after you turn on the server power switch. For details, see the document in
the ExpressBuilder DVD provided with the server. (The utility varies depending on the RAID Controller.) For details on the
data transfer rate, RAID, and RAID System configuration, see the manual provided with the RAID Controller as well as the
document.
IMPORTANT: When LSI Logic SAS CTRL 8708EM is installed, do not let the system enter
hibernation or standby mode.
