Why Arista 7020SR
Non-Blocking Fabric
Wire-speed forwarding with zero oversubscription — every port delivers its full rated bandwidth.
Ultra-Low Latency
Sub-microsecond cut-through switching for latency-sensitive workloads and east-west traffic.
VXLAN & EVPN Ready
Native VXLAN/EVPN support for scalable multi-tenant overlay networks in any data centre.
One operating system for every Arista switch
Arista EOS is a single, consistent operating system running across every switch in your network — from 1 Gbps access to 400 Gbps spine. It's fully programmable, Linux-based and built for automation from day one.
Extensible Operating System
Linux kernel · Multi-agent · State-driven
Fully Programmable
Every EOS feature is accessible via REST API, gRPC and Python — automate anything without vendor-specific tooling.
Open & Extensible
Run custom agents and open-source tools directly on the switch OS — no proprietary SDKs required.
Consistent CLI
One unified CLI across every Arista platform — no relearning when you scale or upgrade hardware.
State-Driven & Telemetry-Ready
Streaming telemetry and state-driven forwarding give real-time visibility into every packet path.
CloudVision: network-wide intelligence
Arista CloudVision provides a single pane of glass for provisioning, telemetry and compliance across your entire Arista estate.
Zero-Touch Provisioning
New switches are provisioned automatically via CloudVision — no manual CLI work required.
Real-Time Telemetry
Streaming telemetry from every switch gives you sub-second visibility into traffic, errors and events.
Change Control & Rollback
Every configuration change is audited and reversible — roll back to any previous state in seconds.
Compliance & Security
Continuous compliance checks detect drift from your golden config and alert before issues escalate.
Where {name} fits in your network
Typical deployment roles for the Arista 7020SR — based on real-world customer architectures.
Standalone / Access
Leaf switch in a 2-tier leaf-spine fabric — connects directly to server racks via 25 GbE downlinks.
Leaf in Fabric
HA access pair for smaller clusters where full leaf-spine isn't required.
