About the HPE P58335-B21 - HPE MR408i-o Gen11 SPDM Storage Controller
The HPE MR408i-o Gen11 SPDM Storage Controller (part number P58335-B21) installs as an OCP 3.0 mezzanine card into HPE ProLiant Gen11 servers, delivering enterprise-grade RAID functionality in a compact, integrated form factor. Built on the Broadcom MegaRAID SAS-4 series ASIC, this controller combines PCIe Gen 4 host connectivity with support for NVMe, SAS 12Gb/s, and SATA 6Gb/s drive interfaces across 8 internal ports. The HPE MR408i-o is designed for storage architects and IT procurement teams deploying mixed-protocol storage environments that demand high-speed data access and reliable redundancy without additional cache module complexity.
Supporting RAID levels 0, 1, 5, 6, 10, 50, and 60, the controller enables flexible capacity and performance configurations for diverse workload patterns. Security is built in through SPDM firmware attestation, protecting controller integrity from boot through operation. HPE integration spans iLO 6, OneView, and Smart Storage Administrator for unified management, with firmware updates delivered via the Integrated Smart Update Manager and Smart Component tools. The controller operates in both RAID and HBA passthrough modes, and supports Windows Server, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and VMware vSphere environments, making it a versatile choice for heterogeneous data center stacks.
Deployment Scenarios
- Mixed-protocol storage consolidation in ProLiant Gen11 DL, ML, and Apollo servers
- High-availability database and virtualization deployments requiring RAID 6 or RAID 10 redundancy
- NVMe-accelerated tiered storage architectures combining fast SSDs with SAS or SATA capacity drives
- Secure, firmware-attested storage infrastructure for regulated compliance environments
- Integrated OCP mezzanine deployment eliminating separate adapter card slot consumption
