About the Mellanox MCX515A-CCAT ConnectX-5 EN Adapter, 1x QSFP28, 10/25/40/50/100GbE
With typical power consumption of approximately 15 W (board only, excluding transceiver) and comprehensive hardware offload capabilities, the Mellanox MCX515A-CCAT ConnectX-5 EN Adapter delivers exceptional efficiency for high-density 100GbE deployments. This single-port QSFP28 adapter supports 10GbE, 25GbE, 40GbE, 50GbE, and 100GbE Ethernet speeds, making it a versatile solution for evolving datacenter and HPC environments. The MCX515A-CCAT connects via PCIe 3.0 x16 host interface in a full-height, half-length form factor, integrating seamlessly into standard server architectures. Mellanox engineering delivers advanced hardware offloads including TCP/UDP checksum, LSO, LRO, VXLAN tunnel offload, NVGRE tunnel offload, and hardware flow steering—all reducing CPU overhead and increasing application throughput. The adapter also supports RoCE v1 and RoCE v2 for RDMA, enabling low-latency communication across converged fabrics.
Network engineers and IT infrastructure teams deploying next-generation datacenters require adapters that combine multi-speed flexibility with intelligent offloading. This Mellanox solution supports up to 127 virtual functions per port via SR-IOV, delivering the density and isolation required for virtualized and containerized workloads. The MCX515A-CCAT operates reliably across 0°C to 55°C, with storage tolerance from -40°C to 70°C, ensuring performance stability in mission-critical environments. Software support spans Linux (MLNX_OFED) and Windows Server (WinOF-2), providing broad OS compatibility. Regulatory certifications—CE, FCC, and RoHS—confirm enterprise-grade compliance.
