HPE Smart Array E208e-p SR Gen10 (8 External Lanes/No Cache) 12G SAS PCIe Plug-in Controller

The HPE 804398-B21 is a Smart Array E208e-p SR Gen10 controller that equips your ProLiant server with reliable, high speed access to external SAS or SATA drives. It installs in a standard PCIe 3.0 x8 slot and provides eight 12G SAS lanes through two Mini-SAS HD ports, so large datasets move smoothly and latency stays low even when multiple disks are active.

For storage architects who need flexible protection levels, the controller supports RAID 0, 1, 5, and 10. A Mixed Mode option lets you run traditional RAID volumes alongside HBA pass-through disks in the same enclosure, which is helpful when you want certain drives managed by the operating system or a software-defined storage stack.

If data security is part of your workflow, the card is ready for encrypted drives and can enable encryption at rest with an optional license. This design allows you to protect sensitive information without adding extra hardware.

The E208e-p SR Gen10 works naturally with HPE external enclosures such as the D3610 and MSA 2040, making it a practical choice for expanding capacity on virtualization clusters, backup repositories, or media servers that have outgrown internal bays. Its plug-in form factor simplifies upgrades in branch offices and primary data centers alike, and the three-year parts-only warranty helps keep long-term maintenance predictable.
