HPE P47781-B21 MR416i-o Gen11 OCP Storage Controller
Overview
The HPE P47781-B21 is an enterprise-grade tri-mode storage controller designed for HPE ProLiant Gen11 servers. This OCP 3.0 form factor card provides a dedicated, high-performance solution for managing internal NVMe, SAS, and SATA drives, making it ideal for data centers requiring versatile and robust storage for mission-critical applications. It offloads storage management from the main CPU, ensuring system resources are optimized for application performance. Engineered for modern workloads, the controller leverages a PCIe 4.0 host interface to deliver significant bandwidth for storage-intensive tasks like database management, virtualization, and data analytics. It features 16 internal lanes and is equipped with 8 GB of flash-backed write cache, which protects data integrity during a power loss and accelerates write performance for demanding applications. The controller fits into the server’s OCP NIC 3.0 slot, offering a flexible, cableless installation that simplifies server configuration and maintenance. This design provides a scalable path for enhancing storage capabilities without consuming a standard PCIe slot. Management is integrated into the HPE ecosystem, including StorCLI and UEFI utilities, allowing for streamlined configuration of RAID arrays and monitoring of drive health.
