Quantum QM87XX Switches Overview
Quantum QM87XX Switches includes four 1U NVIDIA Mellanox Quantum HDR InfiniBand systems based on the Quantum switch ASIC. Each model provides 40 QSFP56 ports supporting up to 200Gb/s per port and 16Tb/s of switching throughput. The category includes internally managed QM8700 switches with an x86 dual-core management processor and MLNX-OS, together with externally managed QM8790 switches. Both configurations are available with P2C or C2P airflow, dual AC power supplies, standard-depth chassis, and rail kits. These systems support HDR fabrics for A100 and A800 compute clusters and H100 and H200 storage networks.
MQM8700-HS2F is a managed 1U Quantum HDR InfiniBand switch with 40 QSFP56 ports supporting up to 200Gb/s per port. It includes an x86 dual-core management processor running MLNX-OS, which provides integrated system and InfiniBand fabric management. The standard-depth chassis has two AC power supplies, P2C airflow from the power-supply side toward the connector side, and an included rail kit.
MQM8700-HS2R provides the same managed 1U architecture, 40 QSFP56 interfaces, and HDR speeds of up to 200Gb/s per port. Its x86 dual-core processor and MLNX-OS support onboard switch and fabric administration. This standard-depth configuration includes two AC power supplies and a rail kit, while its C2P airflow moves cooling air from the connector side toward the power-supply side.
MQM8790-HS2F is an externally managed 1U Quantum HDR InfiniBand switch with 40 QSFP56 ports supporting up to 200Gb/s per port. Unlike the QM8700 models, it does not include the onboard management configuration and is administered through an external host using NVIDIA management tools. The system uses a standard-depth chassis with two AC power supplies, P2C airflow, and an included rail kit.
MQM8790-HS2R combines the externally managed QM8790 configuration with C2P airflow. The 1U standard-depth system provides 40 QSFP56 ports operating at up to 200Gb/s for HDR InfiniBand fabrics. It includes two AC power supplies and a rail kit, while cooling air enters through the connector side and exits through the power-supply side. System firmware and status are managed externally rather than through an onboard MLNX-OS management processor.
FAQ
- What is the practical difference between QM8700 and QM8790?
QM8700 is internally managed, with a dual-core x86 CPU, MLNX-OS, dedicated management and console interfaces, and an onboard subnet manager. QM8790 is externally managed: it omits the management CPU and dedicated management ports and is maintained from a connected host with NVIDIA firmware tools.
- Which model includes an onboard subnet manager?
QM8700 includes an onboard subnet manager, documented for fabrics of up to 2,048 nodes. QM8790 does not; its fabric requires a subnet manager running elsewhere, such as on a connected host. Every InfiniBand subnet needs an active subnet manager.
- How is QM8790 firmware updated?
Use an in-band connection from a host running NVIDIA MFT for standard QM8790 firmware updates. The I²C route is reserved for recovery or debugging by NVIDIA support personnel or trained users; it is not the routine management path. NVIDIA firmware instructions
- What do the F and R suffixes indicate?
The final “F” identifies P2C airflow: air enters at the power-supply side and exits at the connector side. The final “R” identifies C2P airflow, with air moving from the connector side toward the power-supply side.
- Can I mix F- and R-direction replacement parts?
No. All replaceable fan and power-supply components must match the airflow direction of the chassis. NVIDIA states that an airflow mismatch affects heat dissipation, so verify the F or R direction before ordering replacement parts.
