HPE InfiniBand NDR200/Ethernet 200Gb 1-Port OSFP PCIe5 x16 MCX75310AAS-HEAT Adapter

The HPE InfiniBand NDR200/Ethernet 200Gb 1-Port OSFP PCIe5 x16 MCX75310AAS-HEAT Adapter is a high-performance host bus adapter designed for modern data centers that demand ultra-low latency, massive bandwidth, and flexible interconnect options. Built to handle the most demanding workloads—from HPC clusters and AI training to data-intensive analytics and large-scale cloud deployments—this PCIe 5.0 x16 card packs 200Gb of InfiniBand NDR200 and Ethernet connectivity in a compact OSFP form factor. With an integrated heatsink (HEAT) for efficient thermal management, the MCX75310AAS-HEAT adapter is engineered to sustain peak performance in dense, rack-friendly environments while delivering reliable, consistent throughput under load. Simply put, it is a future-proof interconnect solution that accelerates data movement, reduces queueing, and unlocks higher productivity across your most critical applications.

• The MCX75310AAS-HEAT adapter delivers dual-mode 200Gb connectivity—InfiniBand NDR200 for low-latency, high-throughput HPC workloads and Ethernet 200Gb for flexible data-center networking—enabling a single card to support diverse workloads without compromising performance. This makes it ideal for AI inference, simulations, scientific computing, and large-scale data analytics where rapid data transfer and RDMA capabilities translate to faster results and improved resource utilization.
• PCIe 5.0 x16 support provides the highest available bandwidth pathway between the host server and the adapter. This ensures maximum data transfer rates to the CPU and memory subsystem, reducing bottlenecks in data-intensive applications and allowing multiple data streams to move in parallel with minimal contention. The result is predictable, low-latency interconnect performance that scales with your growing workload requirements.
• OSFP form factor and a single InfiniBand port keep cabling and module management streamlined in dense data-center racks. The OSFP connector type is designed for high-speed, hot-pluggable interconnects, enabling you to use standard 200Gb cables and network fabrics with the robust reliability expected from HPE components. The single-port design simplifies network topology while preserving the ability to scale out to larger InfiniBand fabrics as needed.
• Integrated HEAT (heatsink) design enhances thermal performance by dissipating heat generated under sustained, peak workloads. Thermal efficiency is critical in dense rack environments where passive cooling and airflow can be limited. The heatsink helps maintain steady performance, reduces thermal throttling, and contributes to longer component life and more consistent latency at scale.
• Robust reliability and enterprise-grade support from HPE include firmware, driver updates, and interoperability with leading HPC and data-center software ecosystems. The card is designed for long-term deployments in mission-critical environments, with a focus on stability, compatibility across operating systems, and streamlined management within standard data-center workflows.

How to install HPE InfiniBand NDR200/Ethernet 200Gb 1-Port OSFP PCIe5 x16 MCX75310AAS-HEAT Adapter

Installing this PCIe5 x16 adapter is straightforward in supported server platforms. Follow these general steps to ensure a clean, reliable deployment. Always refer to your server’s hardware maintenance guide for model-specific instructions and safety guidelines before starting.

• Power down the server, unplug power cords, and discharge static electricity by touching a grounded metal surface.
• Open the server chassis and locate an available PCIe x16 slot that is compatible with PCIe 5.0 devices. Remove the PCIe slot blank or expansion slot cover if necessary.
• Carefully align the MCX75310AAS-HEAT adapter with the PCIe x16 slot and firmly press it straight down into the slot until the locking mechanism engages. Ensure the card is securely seated and straight in the slot.
• Secure the adapter to the chassis with the appropriate screw to prevent movement during operation. Attach any required cabling to the OSFP port using the correct 200Gb InfiniBand/Ethernet cables that match your network fabric.
• Reassemble the chassis, reconnect power, and boot the server. During the operating system boot, install the latest HPE InfiniBand drivers and firmware for the MCX75310AAS-HEAT adapter. Update management software as needed and verify device presence in the system hardware inventory.
• Configure your InfiniBand and Ethernet networks according to your data center topology. Use your preferred management tools, fabric managers, or orchestration platforms to set up VLANs (if applicable), QoS policies, RDMA settings, and any required routing or switch paths.
• Run validation tests to confirm link status, latency, bandwidth, and error rates. Monitor temperatures to ensure the integrated heatsink maintains safe operating conditions under load.
