HPE MR416i-o Gen11 x16 Lanes 8GB Cache OCP SPDM Storage Controller
P47781-B21 · Refurbished · 1 year warranty
Quantity (units)
Overview
OCP is the form factor to note on the MR416i-o Gen11: the o marks a controller that fits an Open Compute Project style slot rather than a standard PCIe or modular position. It has x16 lanes and 8GB of cache, and the title lists SPDM, a security protocol for device authentication. The HPE part number is P47781-B21.
The 8GB cache is the largest in the Gen11 MR family listed here, which suits write-heavy parity arrays. The Gen11 label ties it to HPE's current server generation.
P47952-001 is the spare part number. Ask us to confirm the drive interface and RAID levels before you order.
Confirm that your server has an OCP slot available before ordering. The controller can be requested new, refurbished or used. New and refurbished units carry a warranty of 1 year or 3 years, and used units carry 90 days.
