Product Review

The Arista DCS-7150S-64-CL-F offers high performance with a throughput of 1.28 Tbps and low latency at 380 ns for SFP+ ports, catering to networks demanding high-speed data transmission. However, its system memory is limited to 4 Gigabytes, which may constrain performance in scenarios requiring extensive data processing. Additionally, the switch supports a maximum of 16 40GbE ports and 64 10GbE ports, providing flexibility in network design but might require additional hardware for expansion beyond these limits.


The Arista DCS-7150S-64-CL-F is a high-performance switch designed for data center and high-frequency trading environments. It features 48 1/10G SFP+ ports and 4 QSFP+ ports, supporting up to 64 10GbE ports or 16 40GbE ports through breakout cables. This flexibility makes it suitable for a wide range of networking demands, providing scalable and efficient network infrastructure. At the core of its performance capabilities, the switch delivers a throughput of 1.28Tbps and a packet processing rate of 960 million packets per second (Mpps). This high level of performance is complemented by a low latency of 380 nanoseconds for SFP+ ports, ensuring rapid data transmission that is critical for applications requiring high-speed connectivity and minimal delay. The switch is equipped with a high precision clock, essential for time-sensitive applications, and supports both front-to-rear and rear-to-front airflow configurations to adapt to different rack setups. This flexibility in airflow direction helps to maintain optimal operating temperatures and enhances the reliability of the system. For redundancy and reliability, the Arista DCS-7150S-64-CL-F includes two AC power supply units (PSUs) and four hot-swappable fans. The power supplies and fans are designed for 1+1 and N+1 redundancy, respectively, ensuring uninterrupted operation and minimal downtime even in the event of a component failure. The hardware specifications of the switch are rounded off with a system memory of 4 gigabytes and a dynamic packet buffer memory of 9.5MB, optimizing the handling of bursty traffic and improving the overall efficiency of data transmission. Additionally, the switch offers a variety of ports for management and connectivity, including: - One 100/1000 management port - One RS-232 serial port (RJ-45) - One USB port These interfaces provide flexible options for system management and configuration, facilitating easy integration into existing network infrastructures. The switch's design also focuses on energy efficiency, with a typical power draw of 224 watts and a maximum of 455 watts. This efficient power usage, combined with its compact size of 19” x 1.75” x 16” and a weight of 19 lbs, makes it an ideal solution for space-constrained environments.
