S6720-EI Series Next-Generation Enhanced 10 GE Switches

S6720-EI Series 10 GE Switches provide high-availability, scalable 10 Gbit/s server access for Internet Data Centers (IDCs) and large traditional data centers. High-performance forwarding (up to 1,080 Mpps), 2.56 Tbit/s total switching capacity, and optional configuration of 4 x 40 GE QSFP+ interface card gives the S6720-EI switches unusual flexibility: use to provide access to high-bandwidth server-based applications, or as a core or aggregation switch in enterprise campus networks.

Intelligent QoS features, comprehensive security, and 1+1 backup of AC and DC power modules ensure secure, reliable operation. For additional flexibility, the 40 Gbit/s QSFP+ ports support long-distance stacking.

High-performance fixed switches to handle applications for data center servers and core campus networks

  • The S6720-EI provides line-speed 10 GE access ports and line-speed 40 GE uplink ports, and supports long-distance stacking with 480 Gbit/s bi-directional stack bandwidth
  • Supports comprehensive security policies, such as anti-DDoS, binding tables, and IPSG, plus reliability mechanisms
  • Provides enhanced QoS capabilities, strong MPLS service processing capabilities, and high scalability. Supports 1+1 backup of AC and DC power modules that can be installed on the same device, as well as sFlow traffic monitoring technology
  • Supports Easy Operation Commander, Zero-Touch Provisioning (ZTP) of new devices, batch device upgrades and patch installation, and faulty device replacement
