Mellanox ConnectX6 OCP 3.0 Adapter

The Mellanox ConnectX6 MCX623432AS-ADAB is a dual-port SFP28 network card built to the OCP 3.0 small form factor. It installs in servers or appliances that accept an SFF OCP module and need 25 Gigabit Ethernet connectivity.

Suits Secure-Boot Environments.

This specific variant ships with Secure Boot enabled and cryptographic acceleration disabled. It fits deployments that require a verified boot chain but do not need hardware encryption offload. Buyers who require crypto offload should select a different variant.

Dual SFP28 Ports at 1/10/25 Gb/s over PCIe 4.0 x16

The card presents two SFP28 cages supporting copper or optical transceivers at 1, 10 or 25 Gb/s Ethernet rates. It connects to the host through a PCI Express 4.0 x16 interface also compatible with PCIe 2.0 and 1.1.

Questions about this item

Which variant should I choose among the ConnectX-6 models listed?

This part number ends in AS-ADAB, which means Crypto Disabled and Secure Boot enabled; the other three variants combine Crypto Enabled or Disabled with Secure Boot on or off.

What throughput will I actually see from the dual 25 Gb/s ports?

Each SFP28 port runs at 1, 10 or 25 Gb/s Ethernet; the x16 PCIe 4.0 link provides enough lane bandwidth for both ports at line rate.

How does the OCP 3.0 form factor and PCIe 4.0 x16 interface limit installation?

The card fits an SFF OCP 3.0 slot measuring 115.00 mm by 76.00 mm and needs a PCIe 4.0 x16 slot (also compatible with 2.0 and 1.1) for full 25 Gb/s performance.
