About the HPE 804394-B21 - HPE Smart Array E208i-p SR Gen10 Controller
The HPE Smart Array E208i-p SR Gen10 Controller (part number 804394-B21) is a PCIe plug-in RAID controller designed to expand storage capacity and performance in HPE ProLiant Gen10 servers. This low-profile card connects via PCIe 3.0 x8 interface and delivers direct-attached storage management through two Mini-SAS HD SFF-8643 connectors, making it an essential component for storage architects and IT procurement teams planning high-capacity, multi-drive deployments.
The E208i-p SR controller supports up to 8 direct-attached drives across both SAS HDD, SATA HDD, SAS SSD, and SATA SSD technologies, with HPE SmartDrive compatibility. It provides flexible RAID configuration options including levels 0, 1, 5, 10, 50, and mixed HBA + RAID modes, enabling workload-specific storage optimization. Drive connectivity operates at 12Gb/s SAS or 6Gb/s SATA speeds. HPE integrates management through iLO, HPE OneView, Smart Storage Administrator (SSA), and SPP firmware, with confirmed operating system support for Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise, and VMware ESXi on Gen10 SPP-supported releases. Note that this non-SEA variant does not include encryption support or battery-backed write cache (BBWC) or flash-backed write cache (FBWC).
Typical Enterprise Applications
- Mid-scale virtualization infrastructure requiring local storage expansion across multiple SAS and SATA drives
- Database servers and transactional workloads leveraging RAID 5 and RAID 10 configurations for data protection
- Backup and archive systems scaling storage capacity without external SAN dependencies
- Hybrid cloud edge deployments in HPE ProLiant DL, ML, and Apollo platforms requiring flexible drive support
- Cost-optimized tiering strategies combining HDD and SSD technologies under unified controller management
