1.3.7 Storage Device SBBs
The storage devices come in either a 3½-inch or a 5¼-inch SBB, as shown in
Figures 1–6 and 1–7 respectively. The SW300 enclosure provides space for 24
3½-inch SBBs, 8 5¼-inch SBBs, or combinations of each. A 3½-inch SBB occupies
one slot in a shelf. A 5¼-inch SBB requires three slots in a shelf.
The disk drive SCSI bus address for 5¼-inch SBBs is usually assigned based
upon the shelf backplane connector but also can be assigned manually in some
SBBs. See the StorageWorks Solutions Shelf and SBB User’s Guide.
The disk drive SCSI bus address for 3½-inch SBBs is usually assigned based
upon the shelf backplane connector.
Not all storage devices are supported by each type of HS array controller. See the
current HS array controller model-specific software product descriptions (SPDs)
and release notes for detailed information.
For a list of the various StorageWorks storage devices that can be utilized in the
SW300, see the StorageWorks Solutions Configuration Guide.
