NVIDIA MCX653106A-HDAT ConnectX-6 Dual-Port 200Gb/s InfiniBand Adapter
Product Overview

The NVIDIA® ConnectX®-6 MCX653106A-HDAT is a high-performance, dual-port smart adapter card engineered to accelerate the most demanding data centers. As a cornerstone of the NVIDIA Quantum InfiniBand platform, this network interface card provides two QSFP56 ports, each capable of 200Gb/s InfiniBand HDR or Ethernet connectivity. Its defining innovation is In-Network Computing, which transforms the network card from a passive data pipe into an active compute element, offloading operations from the CPU to boost application performance and scalability for High-Performance Computing (HPC), Artificial Intelligence (AI), and hyperscale cloud infrastructures.

Core Value Proposition
  • Extreme Performance: Delivers up to 200Gb/s per port (400Gb/s aggregate) with ultra-low latency and up to 215 million messages per second
  • In-Network Computing: Revolutionary technology offloads computation and memory access to dramatically increase system efficiency
  • Built-in Security: Hardware-offloaded XTS-AES 256/512-bit block-level encryption ensures data-in-transit security without CPU overhead
  • Dual-Protocol Flexibility: Supports both InfiniBand HDR (200G) and high-speed Ethernet (up to 200GbE) on the same card
  • Comprehensive Offloads: Advanced offloads for NVMe-of, Storage, MPI, and Virtualization (SR-IOV)

Frequently Asked Questions
Q1: What is the difference between the MCX653106A-HDAT and the MCX653105A-HDAT?
While both are dual-port 200Gb/s ConnectX-6 cards, the specific suffix (e.g., 106A vs 105A) often denotes minor revisions in firmware, component sourcing, or feature enablement. For critical compatibility, always verify the exact OPN against the system's hardware compatibility list.
Q2: Does this card require special drivers or software?
It is supported by standard NVIDIA MLNX_OFED drivers for Linux and WinOF-2 for Windows. For In-Network Computing features, specific libraries like HPC-X or NVIDIA's SHARP software may be required.
Q3: Can I use this card in an Ethernet-only network?
Absolutely. The ConnectX-6 is a dual-protocol card. When connected to an Ethernet switch, it will operate as a high-performance Ethernet network card, supporting RoCE (RDMA over Converged Ethernet).
Q4: What cables are compatible with the QSFP56 ports?
The ports support a wide range of QSFP56 and QSFP28 cables and transceivers for both InfiniBand and Ethernet.
Q5: What is meant by "Block-Level Encryption"?
It encrypts data at the storage block level (typically 512 bytes) rather than the file or full-disk level. This hardware offload secures data in transit transparently with minimal latency impact.
