Arista DCS-7050S-52

The Arista 7050 series 10/40G switches offer wire speed layer 2/3/4 performance
with 52 or 64 ports of 10GbE in a compact 1RU chassis. The 7050S-64 switch offers
48 SFP+ and 4 QSFP+ interfaces while the 7050S-52 switch offers 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 offers a
latency of 800 to 1200 ns in cut-through mode, and a shared 9 MB packet buffer
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 efficiency for the data center. An optional built-in SSD supports advanced
logging, data captures and other services directly on the switch.
