Product Review

The Arista DCS-7124S-F offers a high throughput of 480 Gbps and a packet processing speed of 360 Mpps, supported by a dual-core CPU and 1GB of flash memory, ensuring efficient data handling for demanding network environments. However, its latency of 600 nsec might not meet the requirements of applications needing ultra-low latency. The switch's design includes redundant power supplies, hot-swappable components, and a range of operating temperatures, enhancing its reliability and flexibility in various deployment scenarios.


The Arista DCS-7124S-F is a high-performance, low-latency Layer 2/3/4 switch designed for data center and high-frequency trading environments. This switch is engineered to handle demanding applications, featuring a throughput of 480 Gbps and a processing capacity of 360 million packets per second with a latency of just 600 nanoseconds. At the heart of the DCS-7124S-F is a dual-core x86 CPU, accompanied by 1GB of flash memory and 1GB of main memory, ensuring smooth and efficient operation. The switch comes equipped with 24 SFP/SFP+ ports, providing flexibility in connectivity and network design. This allows for a wide range of optical and copper interfaces, supporting speeds up to 10 Gbps. For management and connectivity, the switch includes two Ethernet management ports, one serial port, and one USB port, facilitating easy access and configuration. The DCS-7124S-F is designed with efficiency and redundancy in mind; it features two 650W AC power supplies with 1+1 redundancy and hot-swappable capabilities, ensuring uninterrupted operation. Similarly, the unit is equipped with five front-to-rear airflow fans, which are also hot-swappable, to maintain optimal operating temperatures. The physical dimensions of the switch are 1.74 x 17.4 x 20.25 inches (44 x 440 x 515mm), and it weighs approximately 26 lbs (11.8kg). This compact form factor allows for efficient use of rack space in dense data center environments. Key specifications include: -
  • Interface Type: SFP/SFP+
  • Hot Swappable PSUs and Fans: Yes
  • Reversible Airflow Option: Yes
The DCS-7124S-F operates within a temperature range of 0 to 40°C and can be stored in temperatures ranging from -40 to 70°C. Its design accommodates a relative humidity of 5 to 95% non-condensing and can operate at altitudes of up to 10,000 feet, ensuring reliability in a variety of environmental conditions. Arista's focus on reliability is further demonstrated by features such as the reversible airflow option, allowing the switch to adapt to different rack setups and cooling strategies. This, combined with the switch's robustness and high-performance specifications, makes the DCS-7124S-F an excellent choice for organizations requiring efficient, high-speed networking capabilities.
