Offered here is a dual-port 25GbE SFP28 network daughter card built on the Mellanox CX4121C controller, identified by Dell part number R887V.
As a Dell part it is intended for PowerEdge servers with the matching slot; confirm the part number against your system. With more than one port, traffic can be split by role or links teamed for redundancy. Direct-attach copper cables suit short in-rack links; optical modules cover longer runs. SFP cages keep the choice of media open: optics for longer runs, direct-attach copper inside the rack. The daughter-card format fits the dedicated network slot on the motherboard, leaving the PCIe slots for other cards. Where parts look alike, the Dell part number settles which revision you have. Driver support varies by operating system and hypervisor release, so check yours first. Check R887V against the service configuration of your Dell system before ordering.
This certified refurbished part has been inspected and bench-tested in Johannesburg.
