What is the port-to-port latency?

Port-to-port latency is 200ns, supported by SwitchX-2 technology, 9 virtual lanes (8 data + 1 management), and a 4x48K entry forwarding database. This low latency optimizes real-time HPC workloads and reduces application delays.

What power options does it support?

Dual redundant hot-plug power supplies accept 100-240VAC at 50-60Hz, with typical consumption of 113W using passive cables or 217W with active cables at FDR. Optional redundant supplies enhance availability for enterprise use.

What management features are available?

Includes I2C RJ45 management port, system reset button, and per-port status LEDs for link/activity. Supports IBTA 1.2.1/1.3 protocols, adaptive routing, congestion control, port mirroring, and SDN for external management.

What are the physical dimensions and weight?

The 1U chassis measures 1.72" H x 16.84" W x 24.7" D and weighs 20.5 lbs (9.3 kg). It is 19-inch rack-mountable with reversible P2C airflow and optional redundant fan drawers for flexible datacenter integration.

What environmental conditions does it support?

Operates at 0-45°C and 5-95% non-condensing humidity, up to 3200m altitude. RoHS-6 compliant design ensures reliability in standard datacenter environments with robust thermal management.

Product overview

The Mellanox SX6025 is a 36-port non-blocking unmanaged 56Gb/s InfiniBand SDN switch system from the SX6000 series, built on SwitchX-2 technology. It features 36 QSFP FDR ports providing 56Gb/s bi-directional bandwidth per port and up to 4Tb/s aggregate switching capacity, with FDR10 support at 2.9Tb/s. Port-to-port latency is 200ns, supported by a 4x48K entry MAC address table and 9 virtual lanes (8 data + 1 management). MTU ranges from 256 to 4K bytes. Management includes I2C RJ45 port and system reset button, with per-port status LEDs. It supports IBTA 1.2.1/1.3 protocols, adaptive routing, congestion control, and port mirroring. Dual redundant hot-plug power supplies (100-240VAC) consume 113W typical with passive cables. The 1U rack-mountable chassis weighs 20.5 lbs, measures 1.72"H x 16.84"W x 24.7"D, operates 0-45°C at 5-95% humidity, and is RoHS-6 compliant. Designed for datacenter-scale HPC and SDN deployments requiring high throughput and low latency.
