Product Description
The NVIDIA Mellanox ConnectX-6 MCX623435AE-CDAB is a single-port 100GbE OCP3.0 adapter built on the ConnectX-6 Dx EN controller (MT28928A0-XCCF-CE) with hardware cryptographic offload enabled. It delivers a 100Gb/s QSFP56 port over a PCIe 4.0 x16 host interface with RoCE v2 RDMA support, while offloading IPsec/TLS encryption and decryption operations to dedicated hardware engines on the adapter, freeing host CPU cycles otherwise spent on software-based cryptography. This makes the MCX623435AE-CDAB well suited for security-conscious cloud and enterprise deployments that require encrypted, line-rate network traffic — such as multi-tenant cloud infrastructure, encrypted storage networks, and regulated data-center environments — without sacrificing the throughput and low latency ConnectX-6 Dx is known for.
