MCX755106AS-HEAT
Mellanox
The MCX755106AS-HEAT is a network adapter from NVIDIA Mellanox’s ConnectX-7 product line. It is designed for server cluster deployments that require high-speed data transmission, supporting both Ethernet and InfiniBand protocol standards. This adapter addresses the rising data exchange demands between nodes in large-scale computing infrastructure.
This adapter is built on the ConnectX-7 controller, with a PCIe 5.0 x16 host interface and dual QSFP112 ports. The hardware design supports simultaneous dual-port data transmission, matching the bandwidth requirements of current high-performance server platforms. The HEAT variant comes with a dedicated cooling module, corresponding to the thermal demands of long-duration operation.
This adapter fits into environments including AI model training clusters, high-performance computing clusters, cloud data centers, distributed storage systems, and financial quantitative analysis platforms. It addresses the growing data transmission demands between GPU servers in large-scale computing setups, supporting data-intensive workload scheduling.

The adapter provides dual-port 200Gb/s maximum transmission rate, with Ethernet speed support ranging from 10G to 200G. Compared with 100G network adapters of previous generations, it delivers higher per-port bandwidth. The PCIe 5.0 x16 host interface provides sufficient bus bandwidth to support full-load operation of dual ports, reducing transmission bottlenecks between the adapter and the host system.
The adapter supports RDMA and GPUDirect technologies. RDMA enables direct data transfer between the network adapter and system memory, bypassing part of the operating system kernel processing flow. GPUDirect supports direct data communication between the adapter and GPU devices, reducing data forwarding steps in GPU cluster scenarios. These features can lower CPU resource occupancy during data transmission, supporting the operation of compute-intensive workloads.
The HEAT version is equipped with a dedicated cooling module, adapted to 24/7 continuous operation scenarios. The product uses industrial-grade PCB substrates and components, with design features for electromagnetic interference resistance in high-density data center environments. The design adapts to the thermal and electromagnetic conditions of high-load server racks.
The adapter supports Secure Boot function, along with enterprise-level security management features. These functions provide access control and firmware verification capabilities for server clusters, supporting the protection of business data transmission in commercial data centers. The adapter also supports standard network management protocols, facilitating unified operation and maintenance for enterprise customers.
The MCX755106AS-HEAT supports 200GbE Ethernet protocol and NDR200 InfiniBand protocol, with backward compatibility for lower-speed Ethernet standards from 10G to 100G.
This network adapter adopts a PCIe 5.0 x16 host interface, compatible with server motherboards that have PCIe 5.0 x16 slots. It can also operate on PCIe 4.0 slots at corresponding bandwidth levels.
This adapter is suitable for AI training clusters, high-performance computing clusters, cloud data centers, distributed storage systems, and other scenarios with requirements for high network bandwidth and controlled transmission latency.
