HPE MR416i-p Gen11 Storage Controller

The HPE MR416i-p Gen11 is a PCI plug-in storage controller with x16 lanes and 8 GB cache. It is built for servers that need a dedicated RAID or HBA adapter with SPDM support. The part number P47777B21 identifies this specific controller model.

PCIe x16 Lane and Cache Constraints

The controller uses a PCIe x16 lane interface, so the host server must provide a compatible full-length slot. Its 8 GB cache capacity sets the maximum amount of write-back data it can buffer. Systems without an x16 slot or with smaller cache requirements will not utilise the controller fully.

8 GB Cache Capacity Decides Fit

The 8 GB cache is the single specification that determines whether this controller matches the workload. Applications needing larger cache pools or different cache architectures will require a different adapter. Buyers who need more cache capacity should select another model.

Questions about this item

Should I choose the MR416i-p Gen11 or another controller version for my server?

The MR416i-p Gen11 uses x16 lanes and 8GB cache; confirm your server supports this plug-in form factor before selecting.

What does the x16 lane count mean once the controller is installed?

x16 lanes provide the full PCIe bandwidth path to the processor, allowing the 8GB cache to operate at its rated throughput.

Which PCIe standard does the plug-in interface use and what does it cap in practice?

The plug-in controller connects via a PCIe x16 interface; the lane width caps the maximum data rate to the x16 electrical limit.
