Overview

Dell 540-BCMX is an InfiniBand adapter based on the Mellanox ConnectX-6 controller, with 1 QSFP56 port at HDR100, which is 100Gb/s InfiniBand. It goes in a low-profile PCIe slot.

InfiniBand cards connect servers to InfiniBand switches, typically in high-performance computing clusters and low-latency storage fabrics, so check that your network uses it before ordering.

Dell's compatibility list begins with PowerEdge C4140, C6420 and C6520. GF90C is listed as an alternative number.

InfiniBand cabling and switches are separate from Ethernet, so this card makes sense only where an InfiniBand fabric already exists or is planned. InfiniBand ports need InfiniBand cables and switches, which are different from the Ethernet equipment in a typical data center, so plan the rest of the fabric before you commit to this card.

New and refurbished units are available, each with a 1 year or 3 years warranty.
