About the NVIDIA MCX631102AN-ACAT ConnectX-6 Dx EN Adapter
This low-profile PCIe adapter form factor fits standard enterprise chassis without requiring full-height slot space, making it ideal for dense server deployments where physical constraints matter as much as performance. The NVIDIA MCX631102AN-ACAT ConnectX-6 Dx EN Adapter delivers 100GbE connectivity through a single QSFP56 port, supporting a full range of Ethernet standards including 50GbE, 40GbE, 25GbE, and 10GbE for flexible network migration paths. Built on PCIe 4.0 x16 host interface technology, this adapter integrates advanced offload engines for stateless processing, VXLAN/GENEVE tunnel acceleration, and hardware OVS acceleration—capabilities that reduce CPU overhead and enable line-rate packet processing in demanding production environments.
Network architects and IT procurement teams standardizing on NVIDIA infrastructure will appreciate the ConnectX-6 Dx's comprehensive feature set: RoCEv2 protocol support for low-latency RDMA workloads, inline cryptography for IPsec and TLS 1.2/1.3 security, and SR-IOV virtualization delivering up to 1,000 Virtual Functions for multi-tenant deployments. The adapter consumes up to 25W and operates reliably across 0°C to 55°C environments, while broad OS support—Linux, Windows Server, VMware ESXi, and FreeBSD—ensures integration into heterogeneous data center stacks. Part number MCX631102AN-ACAT is RoHS compliant and managed via PCIe Management Interface and NCSI, providing full observability within existing monitoring frameworks.
