Connecting controller and mixed drive enclosures

P2000 G3 MSA System controller modules support cabling of 3Gb and 6Gb SAS link-rate LFF and SFF

expansion modules — in mixed fashion — as shown in

Figure 10

on page 32, and as further described

in

Additional cabling considerations

(below); the HP P2000 G3 MSA System Cable Configuration Guide;

and HP white papers (listed on the following page).

Additional cable requirements for drive enclosures

IMPORTANT:

When installing SAS cables, use only supported SAS 4x cables with connectors supporting your

application (6Gb, 3Gb, or both).

Mini-SAS to mini-SAS 0.5m cables are provided with each of the following drive enclosures (one per

expansion module): P2000 6Gb 3.5" 12-drive enclosure and D2700 6Gb drive enclosure.

If additional or longer cables are required, they must be ordered separately (see relevant MSA2000

G2 Quickspecs or P2000 G3 Quickspecs for your products).

The maximum cable length allowed in any configuration is 2m.

When expanding storage capacity, a maximum of eight enclosures — including the controller

enclosure — or one hundred forty nine (149) disk drives are allowed in the array.

P2000 G3 MSA System cable requirements

Figure 1

(below) and

Table 4

on page 27 jointly describe cabling requirements and connection

combinations for P2000 G3 MSA System components. Components are labeled with back-end SAS data

rates and other relevant attributes. Simplified IOM face plates are shown.

Table 3

below provides SAS cable requirements for connection combinations between MSA controller and

expansion modules.

Table 4

on page 27 provides details for cabling expansion modules.

NOTE:

Check Quickspecs addressing your respective product with regard to cabling. Quickspecs can be

found from your HP MSA products page
