The Arista 7020R Series are a purpose built high performance and power efficient solution for high density data center deployments. With a choice of 10G SFP+ or 100Mb/1G RJ45, the switch delivers non-blocking forwarding of up to 1.04Tbps combined with feature rich L2 and L3 switching. The 7020R are designed for the high performance environments as a server edge for 1G leaf and spine designs or a high performance storage network switch, where wire speed L2 and L3 forwarding are combined with advanced features for network virtualization, open monitoring and network analysis, resiliency and architectural flexibility.
Lossless Architecture With Unparalleled Performance and Scale
The Arista 7020R Series Switches uses a deep buffer VOQ architecture consistent with the 7280R Series that eliminates head-of-line blocking and packet drops even in the most congested network scenarios. As a result, the Arista 7020R can handle the most demanding data center requirements with ease, including mixed traffic loads of real-time streaming, multicast, and storage traffic. The switches all use a common dedicated packet processor that delivers consistent features.
The 7020R has a high performance quad core CPU and 8GB of system memory to allow for a combination of larger routing tables, vrfs, additional protocols and faster convergence. With support for Arista FlexRoute engine and large forwarding tables along with EOS NetDB the 7020R enable scalability not natively available in typical 1G switches. AlgoMatchTM, a unique Arista innovation to enable more exible and scalable solutions for access control, policy based forwarding and network telemetry is available on the Arista 7020TRA series.
