HPE MR416i-p Gen11 x16 Lanes 8GB Cache PCI SPDM Plug-in Storage Controller

The HPE P47777-B21 is a plug-in storage controller that lets you add high-performance RAID capability to Gen11 servers without sacrificing valuable PCIe bandwidth. Built on proven Broadcom MegaRAID technology and connected through a PCIe 4.0 slot with sixteen lanes, this controller delivers the low-latency path your applications need when every millisecond counts.

An onboard 8 GB cache buffers heavy read and write bursts, so database transactions, large-scale backups, and virtual machine migrations complete smoothly even during peak I/O cycles. Whether you choose cost-effective 6 Gb SATA drives, higher throughput 12 Gb SAS devices, or the latest 16 Gb NVMe media, the card automatically balances traffic across each interface and supports RAID levels 0, 1, 5, 6, 10, 50, and 60 for the mix of performance and redundancy your workload demands.

Secure encrypted drive support helps protect sensitive data at rest, an advantage for industries that answer to strict compliance standards. Day-to-day administration stays straightforward thanks to the bundled MegaRAID Storage Administrator software and familiar UEFI configuration tools, letting you create arrays, check drive health, and tune cache settings from a single pane of glass.

This controller suits IT teams that run dense virtualization clusters, file and print services, or data analytics nodes and need consistent storage performance as they scale. Installation is as simple as seating the card in an available PCIe slot, cabling your drive backplane, and enabling the desired RAID profile—perfect for both new builds and incremental upgrades in an existing rack.
