RAID controller HPE 804394R-B21 PCI Express 3.0 12 Gbit/s
The HPE Smart Array E208i‑p SR Gen10 controller (HPE 804394R‑B21) is a PCIe 3.0, 12 Gb/s SAS RAID controller designed for internal attached drives in HPE ProLiant Gen10 servers (including DL360, DL380, DL560). It supports RAID levels 0, 1, 5 and 10, provides eight internal SAS lanes for SAS and SATA drives, and occupies a PCIe expansion slot. The controller supports Mixed Mode (RAID and HBA simultaneously) and offers optional Smart Array SR Secure Encryption to protect data at rest.
The controller delivers enterprise-class reliability with 12 Gb/s SAS connectivity while remaining cost-effective for software-defined storage deployments. Built‑in features such as Mixed Mode operation simplify infrastructure by avoiding additional controllers, and integration with HPE management tools (UEFI storage configuration tool and HPE Smart Storage Administrator) enables quick configuration and drive management. Optional encryption and SmartSSD Wear Gauge support improve data protection and integrity monitoring.
Install the controller into an available PCIe expansion slot in a compatible HPE ProLiant Gen10 server. Connect internal SAS or SATA drives to the controller using appropriate cables or backplane connections. Use the UEFI storage configuration tool or HPE Smart Storage Administrator (SSA) to create RAID volumes, configure Mixed Mode if needed, and manage advanced settings. For scripted or remote configuration, leverage iLO RESTful interfaces where supported.
For data protection and compliance, enable Smart Array SR Secure Encryption with the appropriate license and monitor drive health with SmartSSD Wear Gauge. Use firmware and SSA updates from HPE to ensure compatibility and performance.
