22 Installing the enclosures
Connecting controller and MSA2000 3.5 12-drive enclosures
You can connect 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: Connecting an MSA2000 3.5 12-drive enclosure to an MSA2324fc requires mini SAS to
SAS cables. Check the QuickSpecs for an updated list of supported cables. QuickSpecs can be found from
your HP MSA products page at
http://www.hp.com/go/msa. Select MSA SAN Arrays, and then select
your product. The link for QuickSpecs is on the right.
IMPORTANT: The MSA2324fc can also be attached to an MSA70 that is running firmware version 2.18 or
later. For information about the MSA70, see the HP StorageWorks 70 Modular Smart Array Enclosure user
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, Figure 3 shows controller 1A connected to I/O
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 Rear panel
components.
