Figure 11 Cabling connections between MSA 1050 controllers and LFF and SFF drive enclosures
The diagram at left (above) shows fault-tolerant cabling of a dual-controller enclosure cabled to either the
MSA 2050 LFF Disk Enclosure or the MSA 2050 SFF Disk Enclosure 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 (4B), of the last drive enclosure, with connections moving in the opposite
direction (green). Fault-tolerant cabling allows any drive enclosure to fail—or be removed—while maintaining access to
other enclosures.
