RA-B6920-32QC2X

The Ragile RA-B6920-32QC2X is a new generation high performance and high density 400GbE switch designed for cloud-scale datacenter and campus networks, which provide a powerful cache capacity and advanced scheduling mechanism driven large scale line-rate non-blocking network. RA-B6920-32QC2X based on Broadcom BCM56980 chipset deliver 32 400GbE QSFP-DD ports in 1RU systems with an overall throughput of 25.6Tbps. RA-B6920-32QC2X support industry standard optics and cables allowing for ease of migration to 400G. All ports allow a choice of speeds including 400GbE, 200GbE or 100GbE, up to 128 interfaces. RA-B6920-32QC2X 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.
