9.4.3Cabling a Non-UltraSCSI RAID Array Controller to an Externally Terminated Shared SCSI Bus

A RAID array controller provides high performance, high availability, and high connectivity access to SCSI devices through the shared SCSI buses.

Before you connect a RAID controller to a shared SCSI bus, you must install and configure the disks that the controller will use, and ensure that the controller has a unique SCSI ID on the shared bus.

You can configure the HSZ20, HSZ40, and HSZ50 RAID array controllers with one to four SCSI IDs.

Because the HSZ20, HSZ40, and HSZ50 have a wide differential connection on the host side, you connect them to one of the following differential devices:

•KZPSA-BB host bus adapter

•KZPBA-CB host bus adapter

•Another HSZ20, HSZ40, or HSZ50

______________________ Note _______________________

The HSZ20, HSZ40, and HSZ50 cannot operate at UltraSCSI speeds when used with the KZPBA-CB.

You can also use a DS-DWZZH-03 or DS-DWZZH-05 UltraSCSI hub with one of these RAID array controllers and either the KZPSA-BB or KZPBA-CB host bus adapters. UltraSCSI cables are required to make the connection to the hub. UltraSCSI speed is not supported with these RAID array controllers when used with a hub and the KZPBA-CB host bus adapter.
