Figure 5 Cabling connections between P2000 G3 controllers and an MSA70 3Gb drive enclosure
The diagram above shows dual-controller modules connected to dual-expansion modules.
Figure 6 Fault-tolerant cabling: P2000 G3 controllers and P2000 6Gb drive enclosures
The diagram above shows a dual-controller enclosure cabled to P2000 6Gb drive enclosures featuring
dual-expansion modules. Controller module 1A is connected to expansion module 2A, with a chain of
connections cascading down (blue). Controller module 1B is connected to the lower expansion module
(5B), of the last drive enclosure, with connections moving in the opposite direction (green). This logic
applies to the fault tolerant cabling diagrams that follow.
