Product Description
The NVIDIA Mellanox ConnectX-6 Dx MCX623102AC-ADAT is a dual-port 25GbE SFP28 adapter from the ConnectX-6 Dx EN family, connecting through a PCIe 4.0 x16 host interface for maximum bandwidth headroom on x16-standardized platforms. It combines ConnectX-6 Dx's ASAP2 hardware offload engine and hardware-accelerated RoCE v2 RDMA with inline IPsec/TLS crypto acceleration, letting data-in-motion encryption run at line rate without consuming host CPU cycles. Hardware Root-of-Trust with Secure Boot protects firmware integrity, and SR-IOV with NC-SI sideband management supports secure, virtualized multi-tenant deployments with BMC-based out-of-band monitoring. Hardware storage acceleration extends its usefulness to NVMe-oF storage networking, while stateless CPU offloads, jumbo frames, and hardware QoS round out a feature set aimed at security- and performance-sensitive cloud, enterprise, and telco environments needing encrypted 25GbE connectivity with extra PCIe bandwidth headroom for future upgrades.
