* Manufacturing may substitute correct cable length depending on configuration.
Step 6—Storage Controllers
KFTIA-AA included with each Base Server; KFTHA-AA
included with Expanded Base Server—PCI, EISA, and
XMI storage controllers can be added.
- Requires corresponding PCI plug-in unit (DWLPB-
AA/AB/BA/BB) or XMI plug-in unit (DWLMA-
AA/BA).
DWZZA-AA requires minimum revision E02 for
connecting any Fast Wide Differential SCSI-2 port from
KFTIA-AA or KZPSA-BB to TZ8xx tape loaders.
DWZZB-VW Fast Wide Differential Single-ended SCSI
Converter requires minimum revision A01 for connecting
FWD SCSI-2 signals from KFTIA-AA or KZPSA-BB to
BA356-JB StorageWorks Shelf.
System maximum of four KZPSC or KZPAC SCSI
RAID controllers.
Tape and optical devices are not supported on KZPSC or
KZPAC SCSI RAID controllers.
PCI-based Storage Controllers
KZPSA-BB PCI Fast Wide Differential SCSI Adapter—OpenVMS V6.2-1H3 supports eight per PCI,
maximum 26 per system. DIGITAL UNIX supports eight per PCI, maximum 32 per system (uses one
PCI slot). Provides one SCSI-2 bus. KZPSA supports DECsafe Available Server.
BN21K-xx SCSI-2 Fast Wide Differential cables—68-pin male straight to 68-pin male right-angle. Connects
KZPSA-BB Fast Wide Differential SCSI-2 port to DWZZA-VA or DWZZB-VW.
