EXP5000 storage expansion enclosure cabling rules
Refer to these general rules when cabling the storage subsystem to the EXP5000
storage expansion enclosure.
1. Do not connect a combination of more than seven EXP5000 storage expansion
enclosures to the two ports of a dual-ported drive channel. Failure to observe
this limitation might result in loss of data availability.
2. Do not connect more than four EXP5000 storage expansion enclosures to any
port of a dual-ported drive channel.
