What is the switching capacity and performance?

Aggregate bandwidth is 544 Gbps with non-blocking architecture, 204 Mpps forwarding rate, and fabric latency under 0.2µs via cut-through routing. Per-port buffering uses ASIC-embedded memory with 16 credits guaranteed.

Can it stack with other switches?

Yes, 4 x 10/20Gbps stacking ports enable multi-switch fabrics up to 120 ports in stack, cascade, or mesh topologies. Adaptive trunking and intelligent path selection provide resilient connectivity.

Is it compatible with older Fibre Channel gear?

Fully backward-compatible with 2Gb and 4Gb SFPs and devices. Ports auto-negotiate speeds and support public loop, broadcast modes, ensuring smooth migrations in mixed environments.

What management features are included?

As a managed switch, it includes Fabric Security, SANdoctor diagnostics, and NPIV for virtualization. Supports fabric, public loop, and broadcast modes with advanced monitoring.

What are the key scalability options?

Starts with 20 device ports plus 4 stacking ports, expandable via stacking to 120 ports. 20Gb ISL on demand adds bandwidth equivalent to six extra 8Gb ports without hardware changes.
