NVIDIA mellanox ConnectX-6 MCX653106A-ECAT 100Gb/s Dual-Port InfiniBand Adapter

Versatile dual-port 100Gb/s InfiniBand and Ethernet adapter card with PCIe 3.0/4.0 x16 interface—delivering RDMA, NVMe-oF offloads, block-level encryption, and in-network computing for cost-optimized HPC, enterprise, and cloud deployments.

• Dual-port 100Gb/s InfiniBand (EDR/HDR100) and 100/50/40/25/10GbE connectivity
• PCIe Gen 3.0/4.0 x16 (backward compatible) | Up to 215 million messages per second
• Hardware offloads: NVMe-oF target/initiator, XTS-AES 256/512-bit encryption, MPI tag matching
• NVIDIA In-Network Computing and GPUDirect RDMA support
• Low-profile PCIe stand-up form factor, RoHS compliant

• 100Gb/s Throughput: Dual ports operating at up to 100Gb/s InfiniBand (EDR/HDR100) or Ethernet with full bidirectional bandwidth.
• In-Network Computing: Offloads collective operations (MPI, NCCL, SHMEM) using NVIDIA SHARP technology.
• Block-Level Encryption: Hardware AES-XTS 256/512-bit encryption/decryption without CPU overhead; FIPS compliant.
• NVMe-oF Offloads: Target and initiator offloads for NVMe over Fabrics, reducing CPU utilization.
• Advanced Virtualization: SR-IOV up to 1K VFs, ASAP² acceleration for OVS and virtual switching.

The MCX653106A-ECAT integrates NVIDIA In-Network Computing engines (SHARP), RDMA (IBTA 1.3), RoCE, and NVMe-oF. It supports PCIe Gen 4.0 (x16) and Gen 3.0, PAM4 and NRZ SerDes, and advanced features like Dynamically Connected Transport (DCT), On-Demand Paging (ODP), and Adaptive Routing. Overlay offloads for VXLAN, NVGRE, Geneve are hardware-accelerated. Compliant with IEEE 802.3bj, 802.3bm, 802.3by, and InfiniBand Trade Association specifications.

ConnectX-6 offloads communication and storage tasks from the host CPU to the adapter hardware. For MPI collectives, the adapter processes data in transit using SHARP, reducing endpoint traffic. For storage, NVMe-oF commands are processed directly on the adapter, freeing CPU cores. Block encryption/decryption occurs inline at wire speed. The result is lower latency, higher message rate (215 Mpps), and improved application scalability—even at 100Gb/s speeds.

• Mid-Range HPC Clusters: MPI-based simulations requiring cost-effective 100Gb/s interconnect.
• AI Inference & Training: GPU clusters with GPUDirect RDMA and NCCL collectives.
• NVMe-oF Storage: Target/initiator offload for high-performance NVMe storage access.
• Virtualized Data Centers: SR-IOV and ASAP² for OVS offload in NFV and cloud.
• Enterprise Cloud: 100Gb Ethernet connectivity for virtualization and storage convergence.

Note: MCX653106A-ECAT supports 100Gb/s InfiniBand (EDR/HDR100) and 100/50/25/10GbE. Dimensions: 167.65mm x 68.90mm (without bracket). Includes tall bracket (short bracket accessory). Power consumption < 15W typical.

• vs. ConnectX-5: Double the bandwidth (100Gb/s vs. 50Gb/s), integrated SHARP for in-network computing, and block-level encryption at no extra cost.
• vs. Competitor NICs: True hardware offload for NVMe-oF and MPI collectives—not just stateless offloads.
• Cost-Optimized 100G: Ideal for balancing performance and budget in mid-size clusters.
• FIPS Compliance: Hardware encryption meets government security standards.

We offer 24/7 technical consultation, RMA services, and integration support for ConnectX-6 adapters. Each card is backed by a 1-year warranty (extendable). Our team provides driver validation for major Linux distributions, Windows, and VMware. Pre-sales configuration assistance for InfiniBand/Ethernet fabric design is available.

Q: Is the MCX653106A-ECAT compatible with 200Gb/s Quantum switches?

A: Yes, it is interoperable with NVIDIA Quantum QM8700/QM8790 switches when using HDR100 mode (100Gb/s per port).

Q: Can this adapter be used for Ethernet as well as InfiniBand?

A: Yes, it supports both InfiniBand and Ethernet protocols. The firmware auto-detects the switch type and configures the appropriate mode.

Q: Does it support RoCE (RDMA over Converged Ethernet)?

A: Yes, ConnectX-6 fully supports RoCE, providing low-latency RDMA in Ethernet environments.

Q: What is the maximum message rate?

A: The adapter delivers up to 215 million messages per second, ideal for small-packet HPC workloads.

Q: Is the card compatible with PCIe Gen 3.0 slots?

A: Yes, it is fully compatible with PCIe Gen 3.0 x16 slots; performance will be limited to ~100Gb/s aggregate, which matches the port speed.

• PCIe Slot Requirement: For optimal performance, install in a PCIe Gen 3.0 x16 or Gen 4.0 x8/x16 slot.
• Cooling: Ensure adequate airflow in server chassis; passive cooling requires minimum 200 LFM.
• Cabling: Use QSFP56 passive/active copper or optical modules rated for 100Gb/s (EDR/HDR100).
• Driver Support: Use latest NVIDIA MLNX_OFED for Linux or WinOF-2 for Windows.
• Operating Temperature: 0°C to 70°C; store between -40°C and 85°C.
