Arista 7500R Series Universal Spine and Cloud Networks

Designed for large virtualized and cloud networks the Arista 7500R Series modular switches are the industry’s highest performance universal spine switches. They combine 100GbE density with internet scale table sizes and comprehensive L2 and L3 features. Advanced EOS features for network monitoring, precision timing, VXLAN network virtualization are combined with extensive hardware resources with a rich choice of systems and line cards to support lasting investment protection.

The 7500R Series enable highly scalable cloud network designs with MLAG, ECMP and VXLAN technologies.

The Arista 7500R Series FlexRouteTM engine and EOS NetDB provides the scalability to support Internet IP routing scale with the lowest power consumption and fast convergence while scaling to millions of routes.

Available in a compact system design, as a choice of 12, 8 and 4 slot, the Arista 7500R Series enables a full range of wirespeed ports from 1G to 100G. It lowers total cost of ownership as it is designed to be efficient with power per port as low as 25W per 100GbE port which combined with front to rear cooling to optimize the data center environment produces the most reliable, dense and power efficient modular switch.
