HP P2000 G3 SAS MSA System User Guide 25
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 P2000G3MSA System components. Components are labeled with back-end SAS data
rates and other relevant attributes. Simplified IOM face plates are shown.
Figure 1 P2000 G3 MSA System component connection combinations
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 http://www.hp.com/go/p2000
. Quickspecs links are located
