7311 Model D20 internal SCSI cabling

A 7311 Model D20 supports hot-swappable disks using two 6-pack disk bays for a total of 12 disks. Additionally, the SCSI cables (FC 4257) are used to connect a SCSI adapter (any of various features) in slot 7 to each of the 6-packs, or two SCSI adapters, one in slot 4 and one in slot 7. (See Figure 2-12 on page 34.)

Connect the SCSI cable feature to the SCSI adapter

If a SCSI card is also placed in slot 4, wire as shown below:

Note: Any 6-packs and the related SCSI adapter can be assigned to a partition. If one SCSI adapter is connected to both 6-packs, then both 6-packs can be assigned only to the same partition.

2.7.4 7311 I/O drawer and RIO-2 cabling

As described in 2.7, “External I/O subsystems” on page 32, we can connect up to four I/O drawers in the same loop, and up to 20 I/O drawers to the p5-570 system.
