• If you use hard disk drives in the RAID System or change the RAID level,
Important
initialize the hard disk drives. If the hard disk drive contains valuable data,
be sure to backup the hard disk drive before installing the RAID Controller
and configuring the RAID System.
• If both PCI #1 and PCI #2 slots contain RAID cards, OS is installed in hard
disk drive connected to RAID Controller in PCI #2 slot. Use the hard disk
drive connected with RAID card in PCI slot #1 for storing data.
Note
In the RAID System, use hard disk drives that have the same specifications
(capacity, rotational speed, and standard) for each Disk Array.
• Logical Drives can be created even with only one Physical Device.
Tips
• When using SAS hard disk drives, RAID Controllers must be connected.
