Example Of The Maximum Number Of Enclosures; Part Number - HPE MSA 2050 Configuration Manual

Connecting an MSA 2050/D2700 mixed-connect configuration
The following figure shows a dual-controller array connected to MSA 2050 and D2700 disk enclosures. There
are no restrictions to the order of enclosures when adding MSA 2050 disk enclosures and D2700 disk
enclosures.
1. MSA 2050 array controller
2. MSA 2050 disk enclosure
3. D2700 disk enclosure

Example of the maximum number of enclosures

The following figure shows an example of an array configuration that displays the maximum number of
enclosures that are allowed in an array configuration. The maximum number of enclosures allowed, including
the controller enclosure, is eight.
An array is connected to seven disk enclosures. Each disk enclosure contains 12 drives, and the LFF
controller enclosure contains 12 drives. Combined, the total number of drives is 96 LFF drives. No additional
enclosures can be connected, because the maximum of eight enclosures has already been reached.
NOTE:
When connecting more than two disk enclosures, you may be required to purchase additional 1 m
cables or 2 m cables. Spanning six or seven enclosures requires a 2 m Mini-SAS cable to enable the
proper bend radius.
