About the HPE 804331-B21 - HPE Smart Array P408i-a SR Gen10 Controller
The HPE Smart Array P408i-a SR Gen10 Controller (part number 804331-B21) is validated for HPE ProLiant DL, ML, and Apollo Gen10 series servers, with full operating system support across Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware vSphere environments via HPE SPOCK compatibility matrix. This modular, internally mounted mezzanine-style RAID controller is engineered for enterprise storage architects and IT procurement teams seeking reliable, high-performance drive management across demanding datacenter deployments.
The 804331-B21 connects via PCIe 3.0 x8 and manages up to 8 internal SAS/SATA ports with support for up to 32 physical drives when expanders are deployed. It delivers industry-standard performance with 12Gb/s SAS and 6Gb/s SATA drive interface speeds, dual-core ROC (RAID-on-Chip) processing, and a robust 2 GB Flash-Backed Write Cache (FBWC) protected by capacitor-backed energy storage. The controller supports RAID levels 0, 1, 5, 6, 10, 50, and 60, enabling flexible redundancy configurations. Additional features include SmartCache support for SSD read/write caching, mixed volume support, and drive erase functionality. Management is seamlessly integrated with HPE iLO, HPE OneView, HPE Smart Storage Administrator (SSA), and HPE Intelligent Provisioning tools.
Typical Enterprise Use Cases
- High-availability database clusters requiring RAID 5 or RAID 6 protection across 8 to 32 drive configurations
- Virtualized infrastructure on vSphere with Flash-Backed Write Cache accelerating VM I/O and reducing latency
- Mixed SAS/SATA environments leveraging SmartCache for tiered read/write optimization
- Linux-based mission-critical workloads on Red Hat or SUSE platforms with redundant RAID 10 or RAID 50 layouts
- Secure decommissioning workflows utilizing integrated drive erase functionality for compliance and data protection
