Dell Mellanox ConnectX-4 CX4121C 25GbE rNDC Network Daughter Card (R887V)

A rack network daughter card sits in its own dedicated slot on the server board, so it adds networking without using a PCIe slot. The Dell R887V is one of these rNDC cards, and it is built around the Mellanox ConnectX-4 controller, model CX4121C.

Its rated port speed is 25GbE. That suits virtualization hosts, storage networks and other workloads where slower onboard ports have become the bottleneck. The ConnectX-4 family is widely used in data center servers, and this card brings it to systems built around the rNDC format.

Before ordering, confirm that your server has an rNDC slot; this card does not fit a standard PCIe slot.

The R887V can be supplied New or Refurbished. Both conditions come with a choice of 1 year or 3 years of warranty. Send us the server model and the number of cards you need, and we will reply with pricing and lead time.
