Shared storage—with cascaded drive enclosures
This example expands on the cabling paths illustrated in
“Shared storage—dual controller, optimal
cabling, MSA2000sa” (page 103)
and shows connection paths from a dual-controller MSA2012sa
controller enclosure to three cascaded, dual I/O module MSA2000 drive enclosures.
NOTE:
Features of the MSA2000sa and MSA2000sa G2 differ, but cabling and configuration
concepts are the same. This cabling scenario showing the MSA2000sa may also be applied to
the MSA2000sa G2.
