Tru64 UNIX supports a maximum of 64 total SCSI controllers per operating system instance (hardware partition). OpenVMS supports a maximum of
26 total SCSI controllers per operating system instance. Total SCSI controllers (all types) in the system must be within these limits regardless of the
maximum per system I/O adapter limitations. Refer to the "Supported Options List" for specific configuration rules.
Each master PCI drawer contains embedded SCSI controllers (a FIS disk and a CD), which is included in the overall count of SCSI controllers
configured in the system (or partition). Tru64 UNIX counts FIS disk and CD-ROM as an embedded SCSI device. OpenVMS counts the FIS disk only as
an embedded SCSI device. Therefore, one (OpenVMS) or two (Tru64 UNIX) SCSI controllers per master PCI drawer must be included in the total
count of SCSI devices in the system.
Calculating the total number of SCSI controllers in the system (or partition) is done by adding all the devices in the system that the operating system
categorizes as a SCSI device. Tru64 UNIX includes the following devices in this count: KZPBA-CA, KZPBA-CB, 3X-KZPBA-CC, 3X-KZPCA-AA, DS-
KZPCC-CE, DS-KGPSA-CA., DS-KGPSA-DA Fibre Channel, and two embedded master PCI components per master PCI drawer. OpenVMS includes
the following devices in this count: KZPBA-CA, KZPBA-CB, 3X-KZPBA-CC, 3X-KZPCA-AA, 3X-KZPEA-DB, DS-KZPCC-AC, and one embedded master
PCI component per master PCI drawer.
For cluster configurations, use Y cable (BN39A-0G).
Manufacturing may substitute correct cable lengths depending on configuration.

NOTE:
"Per System" quantities apply to systems or to each hardware partition. The SCSI adapters included in the base system or in 3x-DWWPA-AA master
PCI drawers must be included in this calculation.
