Frequently Asked Questions
What is the primary throughput capacity of the Mellanox MQM8790-HS2R switch? +
The MQM8790-HS2R is built on the Quantum HDR architecture, supporting 200Gb/s per port. With 40 QSFP56 ports, it delivers an aggregate switching capacity of 16Tb/s, making it an ideal high-performance backbone for latency-sensitive HPC clusters and data-intensive AI workloads requiring massive bandwidth and minimal overhead.
How does the C2P airflow configuration affect my data center deployment? +
This model utilizes Connector-to-Power (C2P) airflow, meaning cold air enters from the QSFP port side and exhausts out the power supply side. This design is specifically engineered for hot-aisle/cold-aisle data center layouts where racks are oriented to maintain thermal efficiency by pushing heated exhaust toward the hot aisle.
Is the MQM8790-HS2R manageable via software or CLI? +
This specific SKU is categorized as an unmanaged switch. It is designed for environments that require plug-and-play InfiniBand connectivity without the overhead of internal switch management software. It functions as a transparent high-speed fabric element, delegating management tasks to the centralized InfiniBand subnet manager running on your cluster nodes.
Does the MQM8790-HS2R come with the necessary hardware for rack installation? +
Yes, this unit includes the required rail kit for standard-depth rack mounting. The chassis is designed for seamless integration into industry-standard 19-inch racks. We ensure the included hardware is robust enough to support the weight of the dual-power-supply chassis, providing a stable foundation for your networking infrastructure.
What power redundancy options are included with this Quantum switch? +
The MQM8790-HS2R features a dual AC power supply configuration. This redundant design ensures high availability for mission-critical networking environments, allowing the switch to maintain continuous operation even if a single power circuit or power supply unit fails during standard operation.
What port type does the MQM8790-HS2R utilize for 200Gb/s connectivity? +
This switch is equipped with 40 QSFP56 ports. The QSFP56 form factor is essential for supporting HDR InfiniBand speeds, allowing for high-density 200Gb/s connections. It provides the physical density required to scale large-scale fabric topologies while maintaining the signal integrity needed for high-speed data transmission.
Can this switch be used for non-HPC network applications? +
While optimized for high-performance computing and InfiniBand fabrics, the MQM8790-HS2R can be utilized in any environment requiring extreme throughput and ultra-low latency. It is particularly effective for AI training clusters, large-scale storage arrays, and real-time data analytics platforms that demand high-speed interconnects beyond standard Ethernet capabilities.
What is the physical footprint of the MQM8790-HS2R chassis? +
This switch is built with a standard-depth form factor. Its design adheres to conventional rack dimensions, ensuring it fits cleanly into typical server cabinets. By maintaining a standard physical profile, it simplifies cabling management and integrates consistently with your existing server and storage rack layouts.
How can I obtain a bulk quote for multiple MQM8790-HS2R units? +
