What is the switching performance and latency?

Switching capacity is 1280 Gbps with 952 MPPS forwarding rate. Latency is <1.5 µs for 64-byte packets at 10 Gbps, using cut-through architecture for low-latency, wirespeed operation in high-performance environments like HPC or virtualization.

Is it suitable for converged infrastructure?

Yes, dual-personality SFP+ ports support Ethernet and Fiber Channel (4/8Gbps), with 40GbE uplinks, making it ideal for unified LAN/SAN fabrics. High 1280 Gbps capacity and low latency ensure seamless integration in datacenter ToR roles.

What compliance standards does it meet?

Certified to VCCI Class A, EN 55022 Class A, ICES-003 Class A, ANSI C63.4 2003, and AS/NZS CISPR 22 Class A, ensuring electromagnetic compatibility for enterprise datacenter deployments without interference issues.

What is the throughput and use case for uplinks?

952 MPPS throughput supports data-intensive apps. 4 QSFP+ 40GbE uplinks provide aggregation to core, splittable to 16x10GbE, perfect for scaling server access in large racks with non-blocking performance.
