SAS Connectivity Card (CIOv) for IBM BladeCenter
7
One IM or IME volume and IS volume per blade server
z
Two IS volumes per blade server
z
Each blade with an SAS expansion card has access to its assigned HDDs in both DSMs, even if only
z
one SAS Connectivity module is present. Potentially, all 12 drives in both DSMs can be assigned to
the single blade server. However, only 10 HDDs can be used in a single volume. You can create
either two volumes to utilize the capacity of all drives, or designate the remaining two drives as hot
spares.
Both SAS and SATA hot swap HDDs are supported, and intermix of SAS/SATA drives is supported
z
as well. However, each volume must have hard disks of the same type, that is, SAS or SATA.
External disk storage attachments are not supported.

BladeCenter S integrated storage - advanced RAID functionality with shared storage
The configuration shown in Figure 5 connects the SAS Connectivity Card (CIOv) installed in each blade
server to the integrated BladeCenter S storage using two IBM BladeCenter S SAS RAID Controller
Modules in the BladeCenter S chassis. In this configuration, the RAID functionality is provided by the
RAID Controller Modules in the BladeCenter chassis (and not by the RAID controller that is on the blade
server's system planar).

The parts used in this configuration are listed in Table 6.
