Installing the enclosures

Connecting the MSA 2040 controller to the SFF drive enclosure

The SFF D2700 25-drive enclosure, supporting 6 Gb internal disk drive and expander link speeds, can be

attached to an MSA 2040 controller enclosure using supported mini-SAS to mini-SAS cables of 0.5 m

(1.64') to 2 m (6.56') length [see

Figure 10

(page 21)].

Connecting the MSA 2040 controller to the LFF drive enclosure

The LFF MSA 2040 6 Gb 3.5"12-drive enclosure, supporting 6 Gb internal disk drive and expander link

speeds, can be attached to an MSA 2040 controller enclosure using supported mini-SAS to mini-SAS

cables of 0.5 m (1.64') to 2 m (6.56') length [see

Figure 10

(page 21)].

Connecting the MSA 2040 controller to mixed model drive enclosures

MSA 2040 controllers support cabling of 6 Gb SAS link-rate LFF and SFF expansion modules—in mixed

model fashion—as shown in

Figure 13

(page 24), and further described in the HP MSA 2040 Cable

Configuration Guide; the HP MSA 2040 Quick Start Instructions;

QuickSpecs; and HP white papers (listed

Cable requirements for MSA 2040 enclosures

IMPORTANT:
•

When installing SAS cables to expansion modules, use only supported mini-SAS x4 cables with

SFF-8088 connectors supporting your 6 Gb application.

•

Mini-SAS to mini-SAS 0.5 m (1.64') cables are used to connect cascaded enclosures in the rack.

•

See QuickSpecs for information about which cables are provided with your MSA 2040 products.

•

If additional or longer cables are required, they must be ordered separately (see relevant MSA 2040

QuickSpecs or P2000 G3 QuickSpecs for your products).

•

The maximum expansion cable length allowed in any configuration is 2 m (6.56').

•

Cables required, if not included, must be separately purchased.

•

When adding more than two drive enclosures, you may need to purchase additional 1 m or 2 m

cables, depending upon number of enclosures and cabling method used:
• Spanning 3, 4, or 5 drive enclosures requires 1 m (3.28') cables.
• Spanning 6 or 7 drive enclosures requires 2 m (6.56') cables.

•

See Quickspecs (link provided above) regarding information about cables supported for host connection:
• Qualified Fibre Channel SFP and cable options
• Qualified 10GbE iSCSI SFP and cable options
• Qualified 1 Gb RJ-45 SFP and cable options
• Qualified HD mini-SAS cable options
