The Ragile RA-B6920-4S data center switch offers 128-port 100GbE interface in 4RU chassis, which delivers the highest performance combined with complete L2 and L3 forwarding feature in modern large-scale datacenter networks. RA-B6920-4S based on Broadcom BCM56980 (Tomahawk 3) 12.8Tb/s switch ASIC with maximum port density while consuming minimum power and latency. The RA-B6920-4S switch support latency as low as 700ns in cut-through mode, and a 64 MB packet buffer with a large shared pool allowing for superior burst absorption compared to systems with fixed port buffering. RA-B6920-4S support industry standard 100G optics and cables. All ports allow a choice of speeds including 100GbE or 40GbE, up to 128 interfaces.
