What are the port specifications of the Mellanox MSX6790?

The MSX6790 features 36 QSFP ports supporting InfiniBand at 56Gb/s FDR, 40Gb/s QDR, 20Gb/s FDR, and Ethernet at 40GbE/10GbE. This configuration delivers full wire-speed non-blocking performance across all ports with 2.16Tbps total throughput.

What is the switching capacity and latency of MSX6790?

It provides 2.16Tbps full-duplex switching capacity with port-to-port latency below 200ns, ideal for real-time HPC and low-latency applications like AI training where minimal delay is critical.

Is the MSX6790 managed or unmanaged?

The MSX6790 is an unmanaged SwitchX-2 based switch, simplifying deployment in environments prioritizing performance over advanced configuration, suitable for EMC OEM data center integrations.

What power and cooling features does it have?

Dual redundant hot-swappable AC power supplies with 350W typical consumption and front-to-back airflow via efficient fans ensure reliability in 24/7 high-density racks without single points of failure.

What form factor and dimensions apply?

1U rackmount form factor measures 17.3 x 1.7 x 16.9 inches (440 x 43.7 x 430 mm) and weighs 9.5 kg, fitting standard 19-inch racks with short or standard depth options.

Can it integrate InfiniBand and Ethernet fabrics?

Yes, dual-mode support allows seamless operation in mixed environments, enabling a single switch to handle both protocols and reducing infrastructure costs in hybrid data centers.
