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.

http://www.hp.com/support/msa2040/QuickSpecs

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
