HP MSA 2040 Cable Configuration Guide (729691-001, July 2013)

Maximum number of drives example: D2700 drive enclosures
The following figure shows an example of an array configuration that demonstrates the maximum
number of drives that are allowed in an array configuration.
An MSA 2040 array is connected to seven D2700 drive enclosures. Each D2700 drive enclosure
contains 25 disk drives and the MSA 2040 SFF controller enclosure contains 24 disk drives.
Combined, the total number of disk drives in this array configuration add up to the maximum 199
drives allowed.
NOTE: When connecting more than two drive enclosures, you may be required to purchase
additional 1m or 2m cables. Spanning 6 or 7 enclosures requires a 2m mini-SAS cable to enable
the proper bend radius.
