HP Direct-Connect External SAS Storage for HP BladeSystem Solutions Depoyment Guide

MSA2000 with cascaded drive enclosures
This example expands on the cabling paths illustrated in “MSA2000 dual controller, dual domain
optimal cabling” (page 106) and shows connection paths from a dual-controller MSA2012sa
controller enclosure to 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.
