Dell 4-Port 10GbE SFP+ Network Daughter Card — 4X4RK

Offered here is a quad-port 10GbE SFP+ network daughter card, identified by Dell part number 4X4RK.

Dell part numbers identify the exact revision, which matters more than the description when several look-alike parts exist. Driver support varies by operating system and hypervisor release, so check yours first. Hardware offloads on the adapter take checksum and segmentation work off the processors. Tagged VLANs let a single port serve more than one network segment. Multiple ports let one card serve several networks at once, or bond links together for failover. Direct-attach copper cables suit short in-rack links; optical modules cover longer runs. As a Dell part it is intended for PowerEdge servers with the matching slot; confirm the part number against your system. SFP cages keep the choice of media open: optics for longer runs, direct-attach copper inside the rack. Check 4X4RK against the service configuration of your Dell system before ordering.

Certified refurbished condition: the part is inspected, bench-tested and function-checked in Johannesburg.
