The Arista 7050X Series are purpose built 10/40GbE data center switches in compact and energy efficient form factors with wire speed layer 2 and layer 3 features combined with low latency and 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. The 7050SX Series support flexible combinations of 10G and 40G that allow customers to design large leaf and spine networks to accommodate both east-west traffic patterns found in modern data centers, high performance compute and big data environments. Featuring a choice of three different 1RU models and one 2RU model the 7050SX Series deliver high density 1/10G SFP+ based ports and 10/40G ports using QSFP+ or embedded optics with MXP multi-speed ports for higher density. All models in the 7050SX Series delivers rich layer 2 and layer 3 features with wire speed performance up to a maximum performance of 2.56Tbps. The Arista 7050SX switches offer 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 2 watts per 10GbE port the 7050SX Series provide industry leading power efficiency with airflow choices for back to front, or front to back. An optional built-in SSD supports advanced logging, data captures and other services directly on the switch.
