Configuration Guidelines
Before you install the KZPBA–CA host adapter in your computer, you need to become
familiar with the product, the configuration guidelines for the host adapter, and its SCSI
bus. This chapter includes installation guidelines, a description of single-ended SCSI
buses, and sample configurations.
NOTE
If you are familiar with configuration guidelines
and know the configuration that you are installing,
skip to Chapter 3 and begin by installing the host
adapter.
2.1 Configuration Guidelines
More than one KZPBA–CA Host Adapter can be installed in the same host
computer. The number of boards that can be installed is only limited by the
number of PCI slots available in the host computer. Unless a SCSI-bus converter
is used, only single-ended SCSI devices can be directly connected to the single-
ended host adapter. For external UltraSCSI device use, refer to Section 2.5 and to
the
UltraSCSI Configuration Guidelines
(EK–ULTRA–CG) for recommended
configurations; also, refer to our Web page at:
http://www.storage.digital.com/.
Physical Configuration
The Personality Module resides in the BA356 storage shelf. The host adapter
connects directly to the Personality Module using a point-to point cable
connection.
Single-Ended SCSI Bus Configuration
The DS–BA356–XX storage shelf contains two single-ended SCSI buses that are
internally configured as a single bus. A maximum of seven 3½-inch half-height
8-bit or 16-bit SCSI devices in DIGITAL StorageWorks Building Blocks (SBBs)
can be attached to the bus. This bus can be split so that storage shelf can be
configured to have one 3-device bus configuration and one 4-device bus
configuration. This is useful when a specific device requires more than one slot
(such as a tape loader or solid state drive).
