About DCS-7050S-52-R


Product Overview:

DCS-7050S-52-R is one of the most treasured switches of the Arista 7050 series for 52 SFP+ interface and 52 ports of 10GbE for a compact 1RU chassis. The latency in the cut-though mode ranges from 800 to 1200 ns, including a 9 MB packet buffer pool (shared) dynamically allocated to the congested ports. The power consumption of this DCS-7050S-52-R switch with twinax copper cables is surprisingly low; > 2 watts/port. The DCS-7050S-52-R specification includes an optional built-in SSD to support the quick data capturing, the advanced logging system, and few of the other specifications that are directly accessible through the switch.


This DCS-7050S-52-R smartnet 52x1/10GbE ports switches work with the pace of 1.28 terabits/second and 960 million packets per second. Wire speed of this DCS-7050S-52-R switch is L2 and L3 forwarding.
