HPE P47789-B21

MR216i-o Gen11 Storage Controller – PCIe x16 Lanes – No Cache – OCP/SPDM

The HPE P47789-B21 MR216i-o Gen11 storage controller provides RAID support and streamlined connectivity for SAS 12Gb/s and SATA 6Gb/s drives through a PCIe Gen4 x16 interface. Designed without onboard cache, it leverages server resources efficiently and integrates natively with OCP 3.0/ SPDM standards for secure platform device management.

Purpose-built for HPE ProLiant Gen11 servers, this RAID solution ensures compliance, resiliency, and predictable performance. Supporting hot-plug operations, redundancy, and enterprise-class error detection, the MR216i-o is an affordable and stable choice for IT infrastructures that value efficient control without cached hardware complexity.

Features :

The HPE MR216i-o Gen11 controller provides proven RAID delivery across SAS/SATA environments using PCIe Gen4 bandwidth. Integration with OCP SPDM delivers enhanced platform security and monitoring compliance in next‑generation server environments.

Advanced Options :

Hot-plug drive support, RAID levels scaling, and direct integration into HPE iLO and Smart Array management make the controller simple to administer. Its cacheless architecture reduces complexity, power draw, and cost while maintaining reliable redundancy for business‑critical workloads.
