Chapter 2. Cabling the RAID Subsystem Cluster Components

2.3 HUB-Radiant RAID Cluster Layout - (SCSI Interconnect)

To connect two HP host servers to a RAID subsystem via use of a Hub (e.g., a Hub-Radiant RAID cluster layout), reference Figure 2-2 and follow these steps:

1.Attach (compatible) end of the 5M adapter cable (BN38C-05) to the HD68- pin host adapter on Host A.

2.Connect the other end of the adapter cable to a convenient hub port.

3.Attach the compatible end of the short adapter cable (BN38E-0B) to the HD68-pin host adapter on Host B.

4.Connect the other end of the short adapter cable to the end of an UltraSCSI cable (BN37A-05).

5.Attach the remaining end of the UltraSCSI cable to a convenient hub port.

6.Connect one end of an UltraSCSI cable (BN37A-05) to a subsystem controller.

7.Attach the other end of the UltraSCSI cable to the remaining hub port.

8.Connect a terminator (H8863-AA) to the remaining tri-link connector on the subsystem controller.
