What is the latency and throughput performance?

Port-to-port latency is 170ns, with up to 4Tb/s non-blocking switching capacity across 36 ports at 56Gb/s. Features adaptive routing, congestion control, and 9 virtual lanes (8 data +1 management) ensure sustained high performance in demanding HPC environments.

Does it support redundant power and cooling?

Yes, it includes dual redundant hot-plug power supplies (100-240VAC, 50-60Hz) and hot-swappable fan units with front-to-rear or rear-to-front airflow options. Typical consumption is 113W with passive cables, providing high availability for enterprise use.

What form factor and dimensions does it have?

1U rack-mountable chassis measures 1.72''H x 16.84''W x 24.7''D, weighing 20.5 lbs (9.3 kg). Fits standard 19'' racks, ideal for dense data center deployments with redundant PSUs and fans.

Is the SX6025 manageable and what standards does it support?

Fully manageable via console port and external tools, compliant with IBTA 1.2.1 and 1.3. Supports FDR/FDR10 FEC, 256-4Kbyte MTU, port mirroring, and 4x48K entry forwarding database for advanced network management.

What are ideal applications for this switch?

Suited for HPC clusters, scalable InfiniBand fabrics, and data centers needing low-latency 56Gb/s connectivity. Enables multiple subnets, granular QoS for converged traffic, and scales to hundreds of nodes with error-free operation.
