Frequently Asked Questions

What are the primary performance capabilities of the Mellanox MCX653106A-HDAT ConnectX-6 adapter? +

The MCX653106A-HDAT is a high-performance ConnectX-6 Ethernet adapter designed for demanding data center workloads. It delivers 200Gb/s throughput with extremely low latency, making it ideal for high-frequency trading, cloud-native applications, and massive scale-out storage clusters. Its architecture effectively offloads CPU tasks, ensuring consistent performance even under peak network utilization.

Which PCIe generation is supported by the MCX653106A-HDAT NIC? +

This adapter utilizes the PCIe Gen4 x16 interface. This high-bandwidth bus architecture is critical for unlocking the full 200Gb/s potential of the card, preventing bottlenecks between the network and the host system's processor. It is fully backward compatible with PCIe Gen3 slots, though performance will be limited by the throughput constraints of the older PCIe bus generation.

What type of physical connectors are used on the MCX653106A-HDAT? +

The card features dual QSFP56 ports, allowing for high-density connectivity in standard rack configurations. These ports support various cabling options, including Direct Attach Copper (DAC) for short-reach, low-latency connections or Active Optical Cables (AOC) and transceivers for longer distances within the data center, ensuring flexible deployment across different cabinet layouts.

Is the MCX653106A-HDAT compatible with RDMA and RoCE protocols? +

Yes, this adapter supports advanced RDMA (Remote Direct Memory Access) over Converged Ethernet, specifically RoCE v1 and v2. By enabling direct memory access between servers without involving the operating system or CPU, it significantly reduces application latency and overhead, which is essential for modern AI, machine learning, and high-performance computing (HPC) environments.

How does the ConnectX-6 architecture improve data center security? +

The MCX653106A-HDAT incorporates hardware-based security features, including line-rate AES-GCM encryption and decryption. This allows data to be encrypted in transit across the network without placing a processing burden on the host server's CPU. These built-in hardware acceleration engines provide a robust security layer for sensitive data traffic without compromising total network throughput.

What server operating systems are compatible with this Mellanox NIC? +

The card is compatible with a wide range of enterprise-grade operating systems, including major Linux distributions like RHEL, Ubuntu, and SLES, as well as Windows Server environments. Because Mellanox provides mature driver support through the NVIDIA/Mellanox OFED stacks, administrators can expect stable integration into virtualization platforms such as VMware ESXi and various container-orchestration environments.

Can the MCX653106A-HDAT be used in virtualization and containerized environments? +

Absolutely. The adapter features advanced SR-IOV (Single Root I/O Virtualization) capabilities, allowing a single physical port to appear as multiple virtual functions. This is essential for modern cloud environments, enabling high-performance networking directly to individual virtual machines or containers while maintaining hardware-level isolation and security for multi-tenant applications.

What is the form factor and cooling requirement for this PCIe card? +

The MCX653106A-HDAT comes in a standard PCIe low-profile form factor, making it suitable for both 1U and 2U rack-mount servers. It is designed for standard server-grade chassis airflow environments. Due to its high performance, it is recommended to ensure that the server housing the card has adequate internal cooling to maintain optimal operating temperatures under sustained heavy workloads.

How can I obtain a bulk quote for the MCX653106A-HDAT from BuyRouterSwitch.com? +
