HPE MSA 2040 Drive Enclosure
The HPE MSA 2040 drive enclosure adds drive bays to an MSA 2040 array over SAS. The QuickSpecs list the MSA 2040 Energy Star LFF disk enclosure (M0S96A) with two I/O modules, and a carrier-grade DC powered SFF enclosure (BV921C) that is sold only with carrier-grade arrays. The same document names the MSA 2050 LFF and SFF enclosures as the recommended expansion, and notes they need newer controller firmware.

Buying a used MSA 2040 Drive Enclosure: what to check
Match the enclosure to the array generation before buying, because MSA 2050 and MSA 2060 enclosures are not interchangeable with the 2040 ones unless the vendor document says so. Check both I/O modules and the SAS cables.
