Internal Shared Disks
It is important to understand the SCSI ID numbering that is used in the shared
storage area of the ProLiant CL380. The CR3500 Configuration Utility uses
the SCSI IDs when configuring physical drives into drive arrays, so it is
important to relate the SCSI ID with the physical drive position. The SCSI IDs
addressing the six internal shared storage drives are SCSI IDs 9-14. The
remaining SCSI IDs, with the exception of SCSI IDs 6 and 7, which are
reserved for use by the Disk Side Bus connections to the CR3500 Controllers,
are used for representing drives in the external shared storage cabinet.
External Shared Storage Expansion
When more storage is needed than can be provided by the six internal shared
storage drives, you may expand the shared storage capacity by adding a
StorageWorks Enclosure 4214. This extends the Disk Side Bus to provide
more storage capacity. There are two configurations that are supported. A
single bus expansion configuration connects a single ProLiant CL380 to a
StorageWorks Enclosure 4214, and up to eight additional drives can be used
for shared storage. A dual bus expansion configuration allows you to connect
two ProLiant CL380s to a StorageWorks Enclosure 4214 by splitting the bus
in the expansion cabinet.
