Step 2. Connect expansion drive enclosures
If expansion drive enclosures are included in your
environment, connect SAS cables per their cabling
plan, either straight-through or Fault tolerant. Mini-SAS
to Mini-SAS cables are required for each drive
enclosure.
The following drive enclosures are supported:
Drive enclosure model
HP MSA 2040 LFF Disk
Enclosure
HP P2000 LFF Drive
Enclosure
HP D2700 Disk Enclosure
Drive enclosure connection guidelines
Expansion drive enclosures can be connected to
an operational MSA 2040.
Mini-SAS to Mini-SAS 0.5 m (1.64 ft) cables are
provided with MSA 2040, P2000 and D2700
drive enclosures (one for each I/O module).
The maximum length cable supported for
connecting drive enclosures is 2 m (6.56 ft).
Cables longer than those supplied with the drive
enclosure must be purchased separately. For a
list of cables available from HP, see the HP MSA
2040 QuickSpecs.
The maximum number of enclosures supported in
an MSA 2040 solution is eight (one MSA 2040
and up to seven expansion drive enclosures).
Example MSA 2040 drive enclosure connections
MSA 2040 firmware supports both fault-tolerant and
straight-through SAS cabling to cascaded drive
enclosures. For more information about these cabling
schemes and for additional cabling examples, see the
HP MSA 2040 Cabling Configuration Guide.
