HPE P47781-B21 MR416i-o Gen11 x16 Lanes 8GB Cache OCP SPDM RAID Controller

HPE MR416i-o Gen11 RAID Controller

The HPE MR416i-o Gen11 is a storage controller designed for server environments that require hardware RAID management. It connects through an OCP interface using x16 lanes and includes 8GB of onboard cache to accelerate read and write operations. This card targets administrators who need reliable array handling in supported HPE Gen11 platforms.

Sustained Workload Cache Behaviour

Under sustained load the 8GB cache absorbs write bursts and promotes frequently accessed data to reduce latency across the array. The x16 lane width maintains bandwidth during long rebuilds or heavy sequential streams without throttling. OCP SPDM support enables secure monitoring and firmware updates while the controller remains in service. Buyers who need a different lane count or cache size should verify compatibility before ordering.
