Shared Storage-With Double-Density Servers - HP 2000sa Deployment Manual

Shared storage—with double-density servers
This example illustrates recommended cabling when using double-density server blades with shared
storage enclosures such as the MSA2000sa. In this configuration, note the following:
This example shows a dual-controller MSA2012sa controller enclosure and standard cabling.
MSA2300sa controller enclosures (standard and optimal cabling) and single-controller devices
are also supported.
Due to limited ports on the MSA2012sa controller, only standard cabling is available. Standard
cabling offers high availability, but, during a failover, there will be a slight performance
reduction.
For best possible performance, use G2 MSA2300sa controller enclosures. Because the
MSA2300sa controller includes four SAS ports, optimal cabling can be used, ensuring
best-possible availability.
