HPE MR408i-o Gen11 x8 Lanes 4GB Cache OCP SPDM Storage Controller

The HPE P58335-B21 is a storage controller that installs in an OCP NIC 3.0 slot and connects to the server through a PCIe 4.0 x8 interface. By taking advantage of that bandwidth it moves data quickly enough to support virtualization hosts, database servers, and other workloads that place consistent pressure on storage throughput.

This controller works with SATA, SAS, and NVMe drives, so you can mix different media types or migrate from one technology to another without swapping hardware. A 4 GB cache lowers latency for frequently accessed data, while full RAID support across levels 0, 1, 5, 6, 10, 50, and 60 helps protect information and maintain uptime.

Day-to-day management is handled through familiar tools such as MegaRAID Storage Administrator, UEFI interfaces, Redfish, and StorCLI. The board is compatible with widely used operating systems including VMware ESXi, CentOS, Windows Server, Red Hat, SUSE, and Ubuntu, and it also supports secure encrypted drives for compliance focused environments. Whether you are building a new Gen11 server or refreshing storage in an existing rack, this controller provides the mix of speed, flexibility, and resilience that modern data centers expect.
