Product Review

The Arista DCS-7050QX-32S-R switch offers high throughput and packet processing capabilities with a 2.56 Tbps throughput and 1440 Mpps, suitable for high-demand network environments. However, its latency of 550 ns might not meet the needs of applications requiring ultra-low latency. The switch's dual 500W AC power supplies and hot-swappable components ensure high availability and easy maintenance, although its maximum power draw of 302W could be a concern for energy-conscious deployments.


The Arista DCS-7050QX-32S-R is a high-performance switch designed for data center networks. It features 32 QSFP+ ports and 4 SFP+ ports, delivering flexibility for high-speed interconnects. This switch supports up to 96 10GbE ports or 4 1GbE ports through breakout cables, catering to varied networking demands. With a throughput of 2.56 Tbps and a packet forwarding rate of 1440 million packets per second (Mpps), it ensures efficient data processing and transmission. The latency is maintained at 550 nanoseconds, optimizing the speed of operations. The switch is powered by a quad-core x86 CPU, with 4 gigabytes of system memory and an equal capacity of flash storage memory, ensuring smooth operation of networking software and services. It also features 12MB of dynamic buffer allocation, which enhances the handling of bursty traffic, and offers an optional 120 gigabytes of SSD storage for additional software or configuration file storage. Connectivity options include a single 10/100/1000 management port, one RS-232 serial port (RJ-45) for console access, and one USB port for external storage or devices. The Arista DCS-7050QX-32S-R is designed for reliability, featuring hot-swappable dual 500W AC power supplies and four fans, both with N+1 redundancy, ensuring uninterrupted operations even in the event of a component failure.
  • Rear-to-front airflow supports efficient cooling, maintaining optimal performance under varying temperature conditions.
  • Typical power consumption is 150W, with a maximum of 302W, reflecting its energy-efficient design.
  • Compact dimensions (19 x 1.75 x 16 inches) and a weight of 20lbs allow for easy installation in standard racks, optimizing data center space.
The operating temperature range of 0 to 40˚C ensures reliability in diverse environmental conditions, while the storage temperature range of -40 to 70˚C allows for flexibility in warehousing or transportation.
