HPE P47785-B21 MR216i-p Gen11 PCIe Storage Controller
Overview
The HPE P47785-B21 is a versatile and agile PCIe Gen4.0 storage controller designed for HPE ProLiant Gen11 servers. As a foundational component for modern data centers, this plug-in card provides reliable, high-speed connectivity for internal SAS, SATA, and NVMe storage drives, solving the need for essential RAID data protection in mission-critical applications. Based on Broadcom MegaRAID technology, this controller leverages a PCIe 4.0 x8 host interface to deliver the bandwidth required for demanding workloads. Security is a core design principle, with features like HPE's Silicon Root of Trust for firmware authentication and DMTF Security Protection Data Model (SPDM) support, which work together to prevent unauthorized firmware and protect the system from malware. Engineered for seamless integration, the MR216i-p fits a standard half-height, half-length PCIe slot. It is managed through HPE's comprehensive tool suite, including the MegaRAID Storage Administrator (MRSA), StorCLI, and native UEFI system utilities. This allows for consistent configuration, monitoring, and management both in-band and out-of-band via Redfish APIs.
