Product Review

The Arista DCS-7316X-FM-R offers significant scalability and performance, supporting up to 2048 10GbE ports and delivering a throughput of 40 Tbps, catering to high-density networking environments. However, its physical size and power requirements may present challenges in more compact data centers, requiring careful planning for installation and power management. Additionally, the specific requirement for the Fabric-X module in slots 1-4 for proper functionality introduces a limitation in configuration flexibility, potentially impacting deployment strategies in certain network architectures.


The Arista DCS-7316X-FM-R stands out as a high-density, performance-driven networking hardware component designed for the Arista 7316 chassis. This Fabric-X module is specifically engineered to accommodate the first four slots of the chassis, playing a crucial role in the overall system's functionality and efficiency. Key to its design is the rear-to-front air flow mechanism, ensuring optimal cooling and reliable operation under various environmental conditions. This feature is particularly critical in maintaining the performance of the module and the system at large, especially in densely packed data centers where heat management is a paramount concern. The hardware architecture includes two slots dedicated to supervisor modules, sixteen slots for line cards, and four slots reserved for fabric modules. This configuration provides a scalable and flexible platform, allowing for a customized setup to meet specific network demands. Additionally, the system houses eight power supply slots, underscoring its capability to deliver uninterrupted power even in demanding operational scenarios. With 32 fan modules integrated into its design, the Arista DCS-7316X-FM-R emphasizes redundancy and graceful degradation. This ensures that the system remains operational and maintains performance levels even when individual components face issues, thereby minimizing downtime and ensuring network reliability. The physical dimensions of the module measure 32.2 inches in height, 3.7 inches in width, and 15.9 inches in depth, with a weight of 37.2 lbs. Despite its comprehensive feature set, the module maintains a compact and manageable size, facilitating easy integration into data center racks. Power efficiency is another notable aspect with a typical power consumption of 550W and a maximum of 760W. This power efficiency, combined with the high-density capabilities, makes the Arista DCS-7316X-FM-R an environmentally friendly choice for modern data centers.
  • Maximum 10GbE Port Density: 2048 Ports
  • Maximum 40GbE Port Density: 512 Ports
  • Maximum Throughput / Packets per Second: 40 Tbps / 30 Bpps
These specifications highlight the module's capacity to handle extensive data traffic, enabling high-speed connectivity and efficient data transmission across a wide network. The operating environment specifications indicate a minimum temperature of 0°C and a maximum of 40°C, with a storage temperature range from -25°C to 70°C. The module can operate under humidity levels ranging from 5% to 95% and at altitudes from 0 to 10,000 feet. These parameters ensure that the Arista DCS-7316X-FM-R can perform reliably in a wide range of environmental conditions, making it suitable for global deployment. In summary, the Arista DCS-7316X-FM-R is a meticulously engineered module that offers high port density, exceptional throughput, and reliable operation.
