What is the switching capacity and forwarding rate?

Switching capacity ranges from 1.44 Tbps to 2.56 Tbps, with forwarding rates of 1.44 Bpps to 1.8 Bpps. This ensures high-throughput performance for cloud-scale traffic, backed by a 288K MAC address table and up to 16MB dynamic buffer allocation.

What is the latency of this switch?

Latency is as low as 550 nanoseconds in cut-through mode, ideal for HPC and real-time applications. It maintains wire-speed L2/L3 features like 128-way ECMP and VXLAN, minimizing delays even under congestion with shared buffering.

What power and cooling options does it have?

Includes dual redundant hot-swappable AC power supplies with 2x C13-C14 cords and redundant hot-swappable fans. Typical consumption is under 2W per 10GbE port, with rear-to-front airflow in a 1RU chassis for efficient high-density cooling.

What software runs on the Arista 7050SX2-72Q?

Arista EOS (Extensible Operating System) provides advanced automation, network telemetry, virtualization like VXLAN, and features such as 288K MAC entries, 144K IPv4 routes, OpenFlow, and real-time monitoring for scalable data center management.

What are the physical dimensions and operating conditions?

Dimensions are 1.75" H x 19" W x 16" D (43.2 x 43.3 x 44 cm), weighing approximately 20 lbs. It operates from 0°C to 40°C (32°F to 104°F), with out-of-band Ethernet and console management interfaces in a compact 1RU rackmount form.
