Product Review

The Arista DCS-7300-SUP delivers high performance with over 20 Terabits per second fabric capacity and up to 15 billion packets per second, making it suitable for environments requiring high bandwidth and processing capabilities. However, its system memory of 16 GB and flash storage of 4 GB may not meet the needs of all applications, particularly in data-intensive scenarios. Additionally, its energy efficiency, with under 3W per 10GbE port, and flexible cooling options, including reversible airflow, contribute to a lower total cost of ownership and adaptability in various data center layouts.


The Arista DCS-7300-SUP is designed to meet the demands of high-capacity networking requirements, featuring advanced processing and memory capabilities, alongside high-speed connectivity options. At its core, this device is powered by a 2.6GHz quad-core x86 CPU, supporting 64-bit processing to efficiently handle complex network operations. It is equipped with 16GB of system memory and 4GB of flash storage memory, ensuring smooth performance and adequate storage for the operating system and applications. This product delivers exceptional throughput and speed, boasting over 20 Terabits per second of fabric capacity and the ability to process up to 15 billion packets per second. Its design allows for up to 2.56 Terabit per second per line card, providing wire speed L2 and L3 forwarding. Network latency is minimized, with figures below 2 microseconds, ensuring rapid data transmission and reducing delays in high-speed networking environments. Connectivity is a key strength of the Arista DCS-7300-SUP, offering: - 1,024 wire-speed 10GbE ports and 256 wire-speed 40GbE ports, supporting dense network configurations. - A 32 port QSFP+ 40G line card, compatible with Copper, Multimode, and Single-mode options for both 40G and 10G, achieving 960Mpps and maintaining energy efficiency with under 3W power consumption per 10G port. - A 48 port 10GBASE-T line card for 100M/1G/10GbE, along with a 4 port 40GbE QSFP+, accommodating up to 64 10G ports per line card for versatile connectivity options. The chassis is available in two sizes, 8RU and 13RU, and features reversible airflow (front-to-back or back-to-front) to optimize cooling based on the installation environment. This design consideration, along with an average power consumption of under 3W per 10GbE port, contributes to a lower cost of ownership by reducing operational expenses. Arista's commitment to flexibility and control is evident in its network operating system. Users benefit from a fine-grained, truly modular OS that offers full access to the Linux shell and tools, allowing for custom scripting and automation.
