The KZPBA-CB UltraSCSI host adapter:

Is a high-performance PCI option connecting the PCI-based host system
to the devices on a 16-bit, ultrawide differential SCSI bus.

Is a single-channel, ultrawide differential adapter.

Operates at the following speeds:

5 MB/sec narrow SCSI at slow speed

10 MB/sec narrow SCSI at fast speed

20 MB/sec wide differential SCSI

40 MB/sec wide differential UltraSCSI

Even though the KZPBA-CB is an UltraSCSI device, it has an
HD68 connector.

Use the steps in Table 10–2 to set up a KZPSA-BB or KZPBA-CB host bus
adapter for a TruCluster Server cluster that uses radial connection to a
DWZZH UltraSCSI hub with an HSZ40 or HSZ50 RAID array controller.
