The Dell PowerVault MD1200 Expansion provides straightforward storage expansion for organisations that need to extend existing Dell platforms without a disruptive refresh. As a SAS-connected expansion shelf with hot-swappable PSUs, it helps keep capacity growth simple, reliable and cost-effective in data centre environments.
As backup sets, archives and secondary workloads grow, IT teams need a way to add capacity without turning a stable storage environment into a major refresh project.
The Dell PowerVault MD1200 Expansion is designed for organisations that want to extend attached Dell storage with simple, low-cost growth. As a 12-bay direct-attached enclosure, it adds room for more data while keeping expansion aligned to the platform already in place.
With a SAS connection, the shelf supports mixed HDD and SSD media, so teams can match capacity and performance to the workload rather than redesigning the environment. The 144 TB maximum raw capacity gives infrastructure owners meaningful headroom, while hot-swappable PSUs help preserve availability during maintenance.
This approach helps extend the useful life of current storage, protects prior investment and keeps expansion straightforward for teams managing budgets and change windows carefully.

Dell PowerVault MD1200 Expansion is a storage expansion platform for enterprise environments that adds scalable capacity to existing infrastructure while preserving straightforward deployment and operational continuity.
Expansion-Centric Architecture
The enclosure is designed to extend an existing storage environment rather than operate as a standalone system.
Direct SAS Connectivity
6Gb SAS host interfaces provide a clear expansion path for attaching the platform to supported storage infrastructure.
Capacity-Scaling Design
The platform supports up to 144 TB of raw capacity to accommodate growing storage requirements.
Integrated Drive Shelf Model
The expansion chassis concentrates additional disk capacity in a compact form factor for structured storage growth.
Hot-Swappable Power Protection
Hot-swappable PSUs help maintain serviceability without requiring a full system power-down.
Operational Continuity
The expansion design supports storage growth while preserving the existing environment’s operational model.
Deployment Flexibility
The platform can be used in new or refurbished configurations without changing its storage expansion role.
If you need to add capacity without redesigning your storage environment, our Dell experts can help align MD1200 expansion with your existing SAS-based infrastructure.

The Dell PowerVault MD1200 Expansion is a direct-attached storage expansion platform for established Dell environments that need more capacity without replacing the base system. It is built for secondary storage, backup, archive and other growing data sets where low-cost expansion matters more than a new architecture.
In data centres, the MD1200 is commonly deployed alongside existing legacy Dell DAS to extend usable storage for backup repositories, archive volumes and secondary data. It helps teams add capacity cheaply, protect prior investment and avoid the disruption of a full storage refresh when the current platform still has operational life left.
Professional services firms use the MD1200 to grow file shares, project folders and backup storage without changing their core setup. For smaller IT teams and budget-conscious environments, the appeal is straightforward capacity growth with simple day-to-day management and less change risk than replacing the storage platform early.
Healthcare organisations deploy the MD1200 in established storage environments to add room for patient records, departmental data, images and backup copies. It supports steady growth in retained data while keeping critical workloads on the existing platform, which suits sites that need economical expansion rather than a premium performance upgrade.
In finance, the MD1200 is used to expand secondary storage for archived reports, exports and backup data. It gives teams controlled capacity growth at low cost, helping preserve the current storage investment and avoid unnecessary procurement complexity when retention demands continue to rise.
Software development teams fit the MD1200 into legacy build, test and archive environments where extra space is needed for lab data, backups and project history. It provides affordable capacity for non-production workloads without forcing a full storage redesign, which keeps expansion simple for lean engineering and operations teams.
Our team can help design and deploy Dell PowerVault MD1200 Expansion for data centre, professional services, healthcare, finance and software development environments that need practical direct-attached capacity growth.
