Connecting controller and drive enclosures

Figure 15
Cabling connections showing maximum enclosures of mixed model type
The illustration above shows a sample maximum enclosures configuration. The diagram shows mixed
model drive enclosures within the dual-controller array using fault-tolerant cabling. In this example, the LFF
drive enclosures follow the SFF drive enclosures. Given that both drive enclosure models use 6 Gb SAS
link-rate and SAS2.0 expanders, they can be ordered in desired sequence within the array, following the
controller enclosure. MSA 2040 controller enclosures support up to eight enclosures (including the
controller enclosure) for adding storage.
