HPE MR216i-p Gen11 x16 Lanes Without Cache PCI SPDM Plug-in Storage Controller

The HPE P47785-B21 is a Gen11 plug-in storage controller that delivers dependable RAID functionality to servers that need the raw bandwidth of PCIe 4.0 but have no requirement for onboard cache. It slips into a standard PCIe 4.0 x8 slot and opens up 16 storage lanes, so you can run SATA, SAS, or NVMe drives at the speeds they deserve.

Two x8 SlimSAS ports make cabling straightforward and keep the backplane tidy. Whether you are building a mirrored volume for critical data, a striped array for performance, or a combination of both, the controller supports RAID 0, 1, and 10 to cover those needs.

Day-to-day management stays simple. MegaRAID Storage Administrator and StorCLI give you a familiar interface for provisioning and monitoring, while Redfish support lets you plug the card into modern infrastructure-as-code workflows. Compatibility with Windows Server, VMware ESXi, and mainstream Linux distributions means the card drops seamlessly into most data center stacks.

This model skips onboard cache to reduce cost and complexity, making it a smart pick for virtualization hosts, edge servers, or any environment that already relies on fast NVMe media. A three year parts only warranty from HPE rounds out the package, giving administrators confidence that the card will stay in service for the long haul.
