HPE P47789-B21 MR216i-o Gen11 OCP Storage Controller
Overview
The HPE P47789-B21 is an essential storage controller designed for modern data centers running HPE ProLiant Gen11 servers. As a dedicated OCP 3.0 form factor card, it provides a streamlined and secure solution for managing internal storage arrays. It is engineered to solve the need for reliable, high-speed data access for applications that depend on direct-attached NVMe, SAS, or SATA drives, making it ideal for enterprise environments focused on performance and efficiency. This controller leverages a PCIe 4.0 x8 host interface to deliver the high bandwidth required to prevent storage bottlenecks. Its tri-mode capability offers exceptional flexibility, allowing administrators to connect up to 16 internal drives and mix SAS, SATA, and NVMe devices within the same server chassis. This versatility simplifies infrastructure by enabling tiered storage designs for various workloads without requiring multiple, specialized controllers. The controller’s architecture is optimized for RAID 0, 1, and 10 configurations, focusing on data protection and high availability for boot volumes and application datasets. Designed for seamless integration, the MR216i-o Gen11 controller fits into the dedicated OCP NIC 3.0 slot, preserving valuable PCIe slots for other expansion cards. Management is unified through familiar HPE tools, including the MR Storage Administrator (MRSA) and StorCLI, ensuring consistent operational workflows. Its cacheless design makes it a cost-effective choice for environments that do not require write-caching, such as read-intensive applications or software-defined storage deployments.
