SpletThe small buffer switch silicon is used in the Arista 7050X, 7250X, 7060X, 7260X and 7300X/7320X switches, while the large buffer switch silicon is used in the Arista 7048T, 7280E/7280R, and 7500E/7500R switches. Both types of switch product lines have been widely deployed. In this paper we will discuss how the difference in buffer size affects

SpletThe figure shows that for a switch with 64 10GbE ports, a static per-port buffer allocation scheme would require 26.5MB (megabytes) of buffer to meet the target frame loss rate. Using Smart- Buffer and its dynamic, adaptive sharing of resources, the same results can be achieved with 5.52 MB of packet buffer.
