Arista Networks 
introduced a new data center switch boasting sub-500 nanosecond latency. The Arista 7124SX, which is aimed at financial trading and ultra low latency applications, serves as a leaf or access top-of-rack 10 Gigabit Ethernet (GbE) switch. The Arista 7124SX is a wire-speed, 24-port, L2/L3 switch supporting 100Mb, 1GbE and 10 GbE SFP+ based optics and cables in one rack unit.
Arista also introduced Latency Analyzer (LANZ), a new software capability to monitor and analyze network performance, generate early warning of pending congestion events, and track sources of bottlenecks. In addition, a Solid State Disk (SSD) is available as a factory-option and can be used to store packet data captures, LANZ generated historical data, and take full advantage of the Linux based Arista Extensible Operating System (EOS).
