Cabling The Controller Enclosure To Disk Enclosures; Figure 5-3. Scsi Bus Numbers For I/O Modules In The Controller Enclosure - Compaq 112726-001 - ProLiant - 6500 Administrator's Manual

Cabling the Controller Enclosure to Disk Enclosures

Compaq recommends using the shortest UltraSCSI cable length possible to
connect disk enclosures to the controller enclosure. The maximum supported
cable length is 2 meters (6.6 ft). Refer to the documentation provided with
your storage subsystem for further information.
As Figure 5-3 shows, both HSG80 Array Controllers (A and B) connect to six
I/O modules in the controller enclosure. UltraSCSI cables are installed
between these I/O modules in the controller enclosure and one I/O module in
each disk enclosure.
