2. Connect the other end of each Ethernet cable to a network that your management host can access (preferably on the same subnet). Connecting drive enclosures to the P2000 G3 MSA System The P2000 G3 MSA System supports four models of drive enclosures: • HP StorageWorks P2000 6Gb 3.5" 12-drive enclosure • HP StorageWorks D2700 6Gb drive enclosure • HP StorageWorks MSA2000 3Gb 3.5" 12-drive enclosure • HP StorageWorks MSA70 3Gb drive enclosure P2000 G3 MSA System controller enclosures support both 3Gbps and 6Gbps internal disk drive and expander link speeds. Mixing 3Gbps drive enclosures with 6Gbps drive enclosures is supported; however, the mixed-connect drive enclosure environment can result in performance limitations unless configured properly. For more information, see the following white papers at http://www.hp.com/go/p2000: • HP StorageWorks MSA2000 G1 or G2 and P2000 G3 MSA Best Practices • Upgrading the HP StorageWorks MSA2000 G1 to the P2000 G3 MSA • Upgrading the HP StorageWorks MSA2000 G2 to the P2000 G3 MSA Observe the following guidelines when connecting drive enclosures to the P2000 G3 MSA System: • Use only supported SAS 4x cables. • Mini-SAS to mini-SAS 0.5m cables are provided with the P2000 6Gb 3.5" 12-drive enclosure and D2700 6Gb drive enclosure (one per controller). • If longer cables are needed than those supplied with enclosure, they must be purchased separately. See the MSA Quick Specs for details. • The maximum length cable allowed to connect enclosures in any configuration is 2m. • A maximum of eight (8) enclosures (including the array enclosure) OR one hundred forty-nine (149) drives are allowed in the array configuration.

Two servers (1 and 2) are direct-connected to a dual-controller HP StorageWorks P2000 G3 MSA System (3) using Fibre Channel cables. The P2000 G3 is in turn connected to two dual-controller HP StorageWorks P2000 6Gb 3.5" 12-drive enclosures (4 and 5) using mini-SAS to mini-SAS cables in fault-tolerant fashion to ensure maximum fault tolerance protection. Data throughput of the array performs at the 6Gbps internal disk drive and expander link speed rate. NOTE: The figures in this document show only P2000 G3 FC controllers in the array enclosure. Cabling requirements for connecting enclosures containing P2000 G3 FC/iSCSI and P2000 G3 SAS controllers to all supported drive enclosures are identical. SAS expansion cable requirements The following table provides SAS expansion cable requirements for P2000 G3 MSA controllers and drive enclosures connection combinations.
