HPE P26279-B21 Broadcom MegaRAID MR416i-A SAS Controller

The HPE Broadcom MegaRAID MR416i-a is a high-performance storage controller designed to accelerate data access and protect critical information in demanding server environments. Specifically engineered for HPE ProLiant Gen10 Plus servers, this Type-A modular controller provides a robust solution for data centers, cloud services, and high-performance computing (HPC) workloads. It addresses the need for high-speed I/O by leveraging a PCIe 4.0 host interface, effectively eliminating storage bottlenecks for transaction-heavy applications and complex databases. Its core function is to manage and protect data on direct-attached storage with advanced RAID capabilities. At the heart of this controller is its Tri-Mode SerDes technology, which offers exceptional flexibility by supporting NVMe, SAS, and SATA storage devices concurrently. This allows IT administrators to mix and match drive types within the same server chassis, optimizing performance and cost without sacrificing data protection. The controller features a substantial 4GB cache, which significantly improves read and write performance for RAID configurations. With 16 internal lanes, it can handle impressive data throughput, delivering up to 13,700 MB/s of bandwidth and 3 million random read IOPS, ensuring applications remain responsive even under heavy load. Designed for seamless integration, the MR416i-a fits into a dedicated Type-A modular slot on the system board of select HPE ProLiant servers. This form factor saves a standard PCIe slot for other peripherals. Management is streamlined through HPE's comprehensive tool suite, including UEFI System Utilities for initial configuration, the MegaRAID Storage Administrator GUI, and command-line tools like StorCLI for advanced scripting and automation. This controller also integrates with the HPE Silicon Root of Trust, providing firmware authentication to secure the storage subsystem against unauthorized modifications.
