The HPE MSA 2040 Expansion Enclosure provides scalable storage capacity for HPE MSA arrays. Supporting SFF or LFF drives depending on configuration, it enables flexible capacity expansion for growing enterprise workloads.
As application data and backup volumes grow, organisations often reach the limits of their existing storage arrays and need a practical way to expand capacity without replacing working infrastructure.
The HPE MSA 2040 Expansion Enclosure extends the capacity of an existing MSA 2040 array by adding additional disk shelves supporting either 24 small form factor drives or 12 large form factor drives. The enclosure supports both SAS HDDs and SSD media, enabling organisations to increase either storage capacity or performance tiers within the same array. Modern flash support, controller efficiency, and scalable drive options allow the platform to serve mixed business workloads while balancing performance, capacity, and investment discipline.
Connected using 12Gb SAS expansion connectivity, the enclosure integrates directly with the existing MSA controllers and allows multiple shelves to be added as storage requirements increase. Organisations that require a newer expansion shelf for MSA growth may also consider the HPE MSA 2050 Expansion Enclosure, for extending usable capacity while simplifying ongoing platform continuity.
Incremental capacity expansion allows IT teams to respond to growing data requirements while maintaining the same storage platform, management tools, and application integrations already in production.
Our specialists can design and deploy HPE MSA 2040 Expansion Enclosure solutions that extend capacity across existing MSA storage environments.

The HPE MSA 2040 Expansion Enclosure is designed for organisations that need to add direct-attached capacity to an existing MSA 2040 storage environment. It is best suited to installed-base deployments where shared storage demand has grown beyond the controller enclosure and additional SAS drive capacity is needed without replacing the array.
Virtual machine environments often grow faster than the original disk count planned for the array. The MSA 2040 Expansion Enclosure fits these deployments where more shared capacity is needed for expanding VM estates and clustered hosts.
Databases and line-of-business applications can increase storage demand over time even when the core array remains fit for purpose. This enclosure is a practical fit where existing MSA 2040 environments need more usable capacity for active business data.
Some MSA 2040 estates carry backup targets, retained snapshots, or lower-tier operational data alongside production workloads. The enclosure suits these environments where additional disk shelves extend retention capacity without redesigning the storage layer.
Not every storage upgrade needs a full array replacement. The MSA 2040 Expansion Enclosure works well where organisations want to extend the life of a current platform through incremental capacity growth.
Refurbished MSA 2040 environments often need matching expansion to maintain a consistent storage design. This enclosure is well matched to continuity-led projects where compatibility and predictable SAS expansion matter.
Our team can help design and deploy HPE MSA 2040 expansion capacity for virtualisation, application growth, and installed-base storage continuity.
