Shared storage-dual controller, optimal cabling, MSA2000sa This example illustrates optimal cabling for a high-performance, high-availability configuration. In this configuration, note the following: • An additional cable from each switch to each MSA controller offers additional availability and performance. • Connecting each controller to each switch ensures highest availability. 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.

Shared storage—dual controller, optimal cabling, MSA2000sa
This example illustrates optimal cabling for a high-performance, high-availability configuration. In
this configuration, note the following:
•
An additional cable from each switch to each MSA controller offers additional availability
and performance.
•
Connecting each controller to each switch ensures highest availability.
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.
