The Arista 7050 series 10/40G switches o?er wire speed layer 2/3/4 performance with 52 or 64 ports of 10GbE in a compact 1RU chassis. The 7050S-64 switch o?ers 48 SFP+ and 4 QSFP+ interfaces while the 7050S-52 switch o?ers 52 SFP+ interfaces. Each QSFP+ 40GbE port can also operate as four independent 10GbE ports to provide a total of 64 10GbE ports in the 7050S-64 model. The Arista 7050S o?ers a latency of 800 to 1200 ns in cut-through mode, and a shared 9 MB packet bu?er pool that is allocated dynamically to ports that are congested. With a typical power consumption of less than 2 watts/port with twinax copper cables, and less than 3 watts/port with SFP/QSFP lasers, the 7050S 10Gb switches provide industry leading power e?ciency for the data center. An optional built-in SSD supports advanced logging, data captures and other services directly on the switch.
