The Arista 7050QX-32S is a purpose built compact and energy efficient data center switch with wire speed layer 2 and layer 3 features, combined with advanced features for software defined cloud networking. Increased adoption of 10 Gigabit Ethernet servers coupled with applications using higher bandwidth is accelerating the need for dense 10 and 40 Gigabit Ethernet switching. It supports a flexible combination of 10G and 40G in a highly compact form factor that allows customers to design large leaf and spine networks to accommodate east-west traffic patterns found in modern data centers, high performance compute and big data environments. Featuring 32 QSFP+ ports in a 1RU form factor the switch delivers feature rich speed performance with an overall throughput of 2.56 Tbps. For configuration flexibility it supports up to 32x 40GbE ports. The Arista 7050QX-32S offers low latency from 550ns in cut-through mode, and a shared 12 MB packet buffer pool that is allocated dynamically to ports that are congested. With typical power consumption of less than 5 watts per 40GbE port the switch provides impressive power efficiency.
