The HPE 804405-B21 is a Smart Array P408e-p SR Gen10 controller designed for administrators who need reliable external storage connectivity in HPE ProLiant Gen10 servers. It plugs into a PCIe 3.0 x8 slot and opens up eight external 12G SAS lanes, giving you the bandwidth to connect multiple drive enclosures without creating a bottleneck.
Versatility is at the heart of this controller. It works with both SAS and SATA drives and lets you run RAID and HBA modes at the same time, so you can mix high-performance arrays with simple pass-through volumes from a single card. The built-in 4 GB flash-backed write cache guards data during unexpected power loss, helping you keep workloads safe even in demanding environments.
Typical use cases include expanding capacity for virtualization clusters, adding secure backup targets, or building tiered storage pools for data analytics. Pair the controller with HPE D3610, D3710, or D6020 enclosures and you can scale out quickly while keeping management under the same HPE tools you already use. If your organization needs encrypted drives for regulatory compliance, an optional license unlocks data-at-rest protection, with FIPS 140-2 Level 1 certification currently under review.
Installation is straightforward. Slide the card into an available PCIe slot, connect Mini-SAS HD cables to your external enclosure, and complete the setup through the familiar HPE Smart Storage interface. Remember that the Smart Storage Battery, required for full cache protection, is sold separately.
