Product Description
The NVIDIA Mellanox ConnectX-5 MCX562A-ACAB is a dual-port 25 Gigabit Ethernet adapter built on the OCP 3.0 Small Form Factor (SFF) specification, sharing the same silicon and feature set as the MCX562A-ACAI but shipping with a pull-tab bracket for chassis designs that use that retention style. Connecting through a PCIe 3.0 x16 host interface, it provides two 25G SFP28 ports with hardware-accelerated RoCE v2 RDMA, SR-IOV, overlay network offload, and NVMe-oF storage acceleration. Built-in NC-SI host management enables out-of-band monitoring through the platform baseboard management controller, supporting large-scale remote fleet operations. As an OCP 3.0 SFF card, it is designed for tool-less front or rear-panel installation and hot-swap serviceability, making it a practical choice for hyperscale and enterprise data centers standardizing on OCP 3.0 chassis with pull-tab card retention.
