The Arista 7050X runs the same Arista EOS software as all Arista products, simplifying network administration. Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service-software updates and self-healing resiliency.
With Arista EOS, advanced monitoring and automation capabilities such as Zero Touch Provisioning, VMTracer and Linux based tools can be run natively on the switch with the powerful x86 CPU subsystem.

High Availability
The Arista 7050X series switches were designed for high availability from both a software and hardware perspective. Key high availability features include:

• 1+1 hot-swappable power supplies and four N+1 hot-swap fans
• Color coded PSU's and fans
• Live software patching
• Self healing software with Stateful Fault Repair (SFR)
• Smart System Upgrade (SSU) and Accelerated Software Update (ASU)
• Up to 64 10GbE or 40GbE ports per link aggregation group (LAG)
• Multi-chassis LAG for active/active L2 multi-pathing
• Up to 128-way ECMP routing for load balancing and redundancy
