MCX631102AN-ADAT

High-Performance PCIe 4.0 Ethernet NIC featuring RoCE RDMA acceleration with the MCX631102AN-ADAT

The MCX631102AN-ADAT is a dual-port QSFP28 adapter engineered for PCIe 4.0 x8 servers requiring deterministic low-latency Ethernet. With the ConnectX-6 Lx controller, the MCX631102AN-ADAT offloads data-path processing to reduce CPU contention, supports RoCE RDMA for memory-efficient transport, and accelerates storage fabrics through NVMe-over-Fabrics target offload and iSCSI, aligning well with clustered compute and disaggregated storage architectures.

Why Choose the MCX631102AN-ADAT?

The MCX631102AN-ADAT delivers high port density and predictable performance using hardware virtualization and advanced packet/overlay offloads. It scales cleanly across Linux, Windows, and VMware estates while maintaining enterprise-grade reliability.

Mellanox designs adapters with a focus on low-latency signaling, robust driver maturity, and interoperability across modern data centre standards, enabling consistent deployment in mixed workloads.

Key Applications:

RoCE RDMA Ethernet fabrics
Virtualized server networking (SR-IOV)
NVMe-over-Fabrics storage networks
Overlay networking (VXLAN/NVGRE/GENEVE)

At Happyware - Server Hardware you benefit from 24/7 Customer Service to support integration of the MCX631102AN-ADAT into your platform roadmap, and Extended Warranty options up to 6 years to protect lifecycle planning for large-scale rollouts.
