Arista Networks 7124FX Application Switch
Optimized to deliver industry-leading ultra-low latency, cut-through forwarding at sub-500 nanoseconds for both unicast and multicast traffic.
[DCS-7124FX-F]
Details
The 16 standard front panel ports accommodate the full range of 10GbE SFP+ and GbE SFP options, allowing for maximum flexibility and deployment options. The 8 FX ports are directly connected to the user programmable subsystem, providing a flexible and open platform for custom and 3rd party embedded applications.
The integrated subsystem provides a unique capability to run latency sensitive and mission critical applications directly in the switch improving performance and determinism, while reducing overall latency and costs. A built in SSD is included for advanced logging, data captures and supporting embedded applications.
Application Switch Programmability
The Application Switch subsystem includes an advanced FPGA with 160Gbps of wire speed performance and 6.2Million Gates. It’s purpose built for inline programmability and customized forwarding. Potential applications include data stream processing, integrated compute and networking functions for high performance applications, content based forwarding, IDS, and many others. Customers may choose to develop their own logic based on the Arista development kit, offering the ultimate in flexibility and customization. For customers that prefer off-the-shelf applications, Arista partners will provide system integration support and “appliance” images for the Application Switch subsystem.
