Frequently Asked Questions
What is the primary throughput capacity of the Mellanox MQM8790-HS2F? +
The MQM8790-HS2F is a high-performance Quantum HDR InfiniBand switch designed to deliver 200Gb/s throughput per port. With 40 ports available, it provides a massive aggregate switching capacity, making it an ideal backbone for compute-intensive clusters, AI training environments, and large-scale data center fabrics that demand ultra-low latency and high bandwidth.
Does the MQM8790-HS2F support both InfiniBand and Ethernet protocols? +
This specific model, the MQM8790-HS2F, is engineered as an HDR InfiniBand switch. It leverages the NVIDIA Mellanox Quantum architecture to provide native InfiniBand connectivity. While InfiniBand is the primary protocol, it is designed to interoperate seamlessly within high-performance computing ecosystems that require RDMA and advanced traffic management capabilities for specialized networking workloads.
What type of form factor is used by the Mellanox MQM8790-HS2F? +
The MQM8790-HS2F features a standard 1U rack-mountable chassis. Its compact design is optimized for high-density deployments in standard server racks, allowing administrators to maximize port density in limited space without sacrificing thermal efficiency or high-speed connectivity performance required in modern enterprise data centers.
How do I manage the MQM8790-HS2F within a large network environment? +
This managed switch supports robust management capabilities via an integrated management interface. Network administrators can utilize standard industry management tools to configure ports, monitor link status, and perform diagnostic tasks. This ensures efficient oversight of the network fabric, reducing operational overhead while maintaining the high availability required for critical compute clusters.
Can the MQM8790-HS2F be used for AI and machine learning workloads? +
Absolutely. The MQM8790-HS2F is purpose-built for the intensive demands of AI and machine learning. Its high port density and 200Gb/s HDR InfiniBand performance provide the necessary interconnect speed for distributed training models. By minimizing latency and maximizing throughput, this switch ensures that GPU communication bottlenecks are eliminated during complex computational tasks.
What kind of cable connectors are compatible with the 40 ports on this switch? +
The 40 ports on the MQM8790-HS2F utilize QSFP56 interfaces. These connectors support HDR InfiniBand transceivers and direct-attach copper cables (DAC) or active optical cables (AOC). Users should ensure that their cabling infrastructure is rated for the 200Gb/s speeds supported by the switch to maintain signal integrity and performance across the entire network topology.
What is the reliability profile of the Mellanox Quantum-based switches? +
Mellanox Quantum-based switches like the MQM8790-HS2F are renowned for their reliability in high-uptime environments. They incorporate advanced self-healing features and sophisticated traffic management algorithms to ensure consistent packet delivery even under heavy loads. This makes them a preferred choice for tier-one data centers where network downtime is not an option.
Are there specific power and cooling requirements for deploying the MQM8790-HS2F? +
As a 1U high-density switch, the MQM8790-HS2F requires adequate airflow management. It is designed with front-to-back or back-to-front cooling paths to align with modern hot-aisle/cold-aisle rack configurations. IT managers should ensure their rack cooling solution provides sufficient CFM to maintain optimal operating temperatures for the onboard components under full load.
How can I obtain a bulk quote for multiple MQM8790-HS2F units? +
