RAID Setup Procedure
Each SBI-7128R-C6/C6N blade module supports up to three hard drives, which may be
used to create a RAID 0, 1 and 5 (Windows) or RAID 0, 1 and 10 (Linux) array. For RAID
setup use the procedure below. This blade’s BIOS has a RAID utility available in its
setup.
5-1 RAID Configurations
With two or hard drives per blade, the following RAID configurations are supported:
• RAID 0 (Data Striping): this writes data in parallel, interleaved (“striped”) sections on
two hard drives. Data transfer rate is doubled over using a single disk.
• RAID1 (Data Mirroring): an identical data image from one drive is copied to another
drive. The second drive must be the same size or larger than the first drive.
• Enhanced RAID 5 or RAID 10 (Data Mirroring): as RAID1 with data mirrored from
one or more disks to one or more disks of a second, larger size. You can couple the
disks from the source to create a virtual volume and use one or more disks of a
second, larger size to provide a single larger volume (or multiple larger volumes)
that serve as the mirroring drive or drives for the array.
5-2 Preparing for Setup
Before you begin the installation, verify the following:
1. The SBI-7128R-C6/C6N blade module has two or more hard drives installed.
2. These drives must not have an OS installed and must be non-partitioned (formatted
is ok).
3. The installation procedure is done via KVM, so have a KVM cable (CBL-0218L)
connected to the KVM connector on the blade module with a keyboard, mouse and
monitor attached.
NOTE: You may also instead use IPMI or the Web-based Management utility to
access the blade.
