Connecting Controller And Msa2000 3.5 12-Drive Enclosures; Cabling Connections Between A Single-Controller Enclosure And One Msa2000 3.5 12-Drive Enclosure - HP StorageWorks 2000fc - G2 Modular Smart Array User Manual

Connecting controller and MSA2000 3.5 12-drive enclosures

You can connect up to four MSA2000 3.5 12-drive enclosures to an MSA2312fc and up to three
MSA2000 3.5 12-drive enclosures to an MSA2324fc. The cabling diagrams shown in this section show the
recommended fault-tolerant cabling patterns.
IMPORTANT:
mini SAS to SAS cables.
IMPORTANT:
Check the QuickSpecs for an updated list of supported cables. QuickSpecs can be found from your HP

guide located on the MSA2000 Software Support/Documentation CD shipped with your product or at
http://hp.com/support/manuals.
When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault
tolerance. Controllers and I/O (expansion) modules are identified by
<enclosure-ID><controller-ID>. For example,
module 2A, and the chain of connections continuing down. Controller 1B is connected to the lower
module (B) of the last drive enclosure in the chain, with connections moving in the opposite direction.
NOTE: For clarity, the schematic illustrations of the controllers shown in this section show only relevant
details such as expansion ports. For detailed illustrations showing all components, see
components.
