About the Mellanox MCX562A-ACAB ConnectX-5 EN OCP 3.0 Adapter, 2x SFP28, 10/25GbE
The Mellanox MCX562A-ACAB ConnectX-5 EN OCP 3.0 Adapter delivers dual SFP28 ports supporting 10GbE and 25GbE connectivity in a compact Open Compute Project Mezzanine form factor. This Mellanox network interface card integrates seamlessly into OCP 3.0–compliant server architectures via a PCIe 3.0 x16 host interface, eliminating the need for auxiliary power by drawing supply directly from the OCP 3.0 connector. Built on the ConnectX-5 EN platform from Mellanox (NVIDIA), the MCX562A-ACAB supports both IEEE 802.3ae (10GbE) and IEEE 802.3by (25GbE) standards, enabling flexible network scaling within hyperscale and enterprise data centers.
Network architects and IT infrastructure teams benefit from advanced hardware offloads including TCP/UDP/IP checksum acceleration, Large Send Offload (LSO), Large Receive Offload (LRO), VXLAN, and NVGRE, along with intelligent flow steering for optimized packet processing. The adapter supports Remote Direct Memory Access (RDMA) via both RoCE v1 and RoCE v2 protocols, essential for low-latency, high-throughput workloads. SR-IOV functionality provisions up to 256 Virtual Functions per port, enabling secure multi-tenant deployments and virtualized environments. Operating system support spans Linux, Windows Server, and VMware ESXi, with driver availability via MLNX_OFED and inbox driver stacks. Engineered for demanding thermal conditions, the unit operates reliably from 0°C to 55°C and stores safely between –40°C and 70°C.
