Product Review

The Arista DCS-7050SX2-72Q-F switch offers a high throughput of 1.44Tbps and a packet processing capability of 1080 Mpps, ensuring efficient handling of network traffic. However, its latency of 550 ns, while adequate for many applications, may not meet the requirements of ultra-low latency environments. Additionally, the switch provides a comprehensive port configuration with 48x10GbE and 6x40GbE interfaces, but its operating temperature range of 0 to 40°C could limit deployment in environments with extreme temperature conditions.


The Arista DCS-7050SX2-72Q-F is a high-performance switch designed to meet the demands of modern data centers and high-bandwidth applications. With a focus on speed, reliability, and scalability, this switch offers a comprehensive set of features tailored for efficient data handling and network management. At the heart of its hardware specifications is the capability to support 48x10GbE (SFP+) and 6x40GbE (QSFP+) ports, providing a versatile platform for aggregating high-speed connections. This configuration enables the switch to handle a total of 72 10GbE ports when accounting for the QSFP+ ports, which can be split into 10GbE interfaces, thus offering ample connectivity options for a variety of network designs. The switch boasts a throughput of 1.44Tbps and can process up to 1080 million packets per second (Mpps), ensuring swift data transmission across the network with a latency of just 550 nanoseconds. This performance level makes the Arista DCS-7050SX2-72Q-F suitable for environments where speed and low latency are critical, such as financial trading platforms and high-performance computing clusters. Underpinning these capabilities is a quad-core x86 CPU, accompanied by 4 Gigabytes of system memory and 4 Gigabytes of flash storage memory. This processing power allows the switch to efficiently manage network traffic and run complex routing protocols without performance degradation. Additionally, the switch is equipped with 12MB of dynamic buffer allocation, enhancing its ability to handle bursty traffic and prevent packet loss during peak loads. For management and connectivity, the switch includes: - A single 10/100/1000 management port for local or remote network administration. - One RS-232 serial port (RJ-45) for console access. - Two USB ports for additional storage or firmware updates. The Arista DCS-7050SX2-72Q-F is designed with redundancy and reliability in mind, featuring two hot-swap power supplies (1+1 redundant) and four hot-swappable fans (N+1 redundant) to ensure uninterrupted operation. This dual AC power supply configuration, along with the included C13-C14 cords, provides a resilient power solution, minimizing downtime due to power supply failures. Operating efficiently, the switch has a typical power draw of 144W and can reach a maximum of 261W under full load. Its compact size (19 x 1.75 x 16 inches) and lightweight design (17.3lbs) make it easy to integrate into existing rack spaces without requiring significant modifications. Designed to operate in a range of environmental conditions, the Arista DCS-7050SX2-72Q-F can function in temperatures from 0 to 40°C and be stored in temperatures ranging from -25 to 70°C.
