What is the switching performance?

The switch delivers 4 Tbps switching capacity, 1 Bpps forwarding rate, and 800 ns latency. With 32 MB dynamic packet buffering, it handles high-throughput L2/L3 traffic efficiently in datacenter leaf-spine setups.

What power and form factor options are available?

It's a 1RU rack-mountable switch with 2x hot-swap AC power supplies in 1+1 redundant configuration and rear-to-front airflow. This ensures high availability and fits standard 19-inch racks with dimensions 1.75x17.3x16 inches.

What are the memory and processor specs?

Equipped with a Quad-Core x86 processor, 8 GB DRAM system memory, and 8 GB flash storage. These support Arista EOS for rich L2/L3 features, large routing tables, and programmable management.

What environmental conditions does it support?

Operating temperature 0 to 40°C (32-104°F), storage -40 to 70°C, 5-95% relative humidity non-condensing, and altitude up to 10,000 ft (3,000m). Suitable for standard datacenter environments.

Is it suitable for low-latency applications?

Yes, with 800 ns latency, 4 Tbps non-blocking throughput, and 1 Bpps forwarding, it's optimized for AI/ML, high-frequency trading, and cloud workloads requiring minimal jitter and high performance.
