MSA2000sa G2 with two c-Class enclosures,
This example illustrates cabling from two BladeSystem c-Class enclosures to one MSA2300sa
controller enclosure. In this configuration, note the following:
• This example shows a dual-controller MSA2300sa controller enclosure with optimal cabling.
Standard cabling is also supported. Standard cabling offers high availability, but, during a
failover, there will be a slight performance reduction.
• Because the MSA2300sa controller includes four SAS ports, optimal cabling can be used,
ensuring best-possible availability.
