The HPE D3700 Disk Enclosure provides high-density storage expansion for HPE ProLiant servers. Supporting up to 25 SFF SAS drives in a 2U chassis, it enables scalable performance and capacity for data-intensive applications.
Data-driven organisations often require high-density storage expansion capable of supporting large datasets within limited rack space.
The HPE D3700 Disk Enclosure provides 25 small-form-factor drive bays supporting SAS or SATA drives, enabling high-density storage expansion for HPE ProLiant environments. Modular shelf expansion introduces additional SSD or HDD capacity behind the existing array or server controllers, preserving the wider storage architecture already in production.
The enclosure connects through 12 Gb/s SAS interfaces, ensuring high-speed connectivity between servers and attached storage devices. That approach lets teams add usable capacity when needed instead of replacing the core platform too early, which is particularly valuable when retention requirements or backup volumes rise unexpectedly. Organisations that require large-form-factor direct-attached expansion within the current D3000 generation may also consider the HPE D3700 Disk Enclosure, for adding LFF capacity while aligning to newer platform generation and enclosure compatibility.
By delivering dense drive capacity within a compact enclosure, the D3700 allows organisations to expand storage capacity while preserving valuable rack space. Incremental growth reduces disruption, protects previous infrastructure investment, and gives the business a cost-controlled way to keep pace with expanding data sets.
Our specialists can design and deploy HPE D3700 Disk Enclosure solutions tailored to scalable enterprise storage environments.

The HPE D3700 Disk Enclosure is designed for organisations that need direct-attached external storage expansion in a 2U small form factor enclosure. It is best suited to environments that need higher drive density for server-attached storage, backup capacity, and departmental data growth without moving to shared storage architecture.
Server environments with growing storage demand often need more drives in a compact footprint. The D3700 is commonly used where additional SFF capacity must be attached directly to the server while preserving a straightforward SAS design.
Virtualisation hosts frequently need more attached storage for local VM datasets, application volumes, or supporting infrastructure services. The D3700 fits these deployments where increased drive count supports denser server-based storage layouts.
Smaller IT environments often need more capacity without the cost and operational overhead of SAN or NAS deployment. The D3700 works well where direct-attached storage expansion keeps the design simple and easy to manage.
Backup repositories and archive-led workloads often need additional disk shelves with predictable expansion paths. The D3700 is a practical fit where capacity growth matters more than shared-storage features or multi-host fabric design.
The D3700 also suits environments adding modular SAS storage to existing server infrastructure. It supports tiered direct-attached storage plans where data growth needs to stay close to the host and scale in manageable steps.
Our team can help design and deploy HPE D3700 storage expansion for server capacity growth, backup, and direct-attached SAS environments.
