HP MSA 1040 Cable Configuration Guide (762786-001, March 2014)

Maximum number of enclosures example: HP MSA 2040 drive enclosures
The following figure shows an example of an array configuration that demonstrates the maximum
number of enclosures (four, including the controller enclosure) that are allowed in an array
configuration.
An HP MSA 1040 array is connected to three HP MSA 2040 drive enclosures. Each HP MSA
2040 drive enclosure contains 12 drives, and the HP MSA 1040 LFF controller enclosure contains
12 drives. Combined, the total number of drives adds up to 48 LFF drives, but no additional
enclosures can be connected, because the maximum of 4 enclosures has already been reached.
NOTE: When connecting more than two drive enclosures(maximum of four enclosures total), you
may be required to purchase additional 1m or 2m cables.
