Description

The Arista 7130 Series is a Layer 1+ FPGA-enabled switch built for ultra-low latency trading, exchange connectivity, market data fan-out and precision network monitoring. This 1U model combines a Xilinx Virtex UltraScale+ VU9P Speed Grade 3 FPGA with an onboard atomic clock, making it suited to colocation environments and teams developing custom FPGA applications.

It provides 48 SFP+ ports supporting 100M to 11.3Gbps, plus 2 RJ45 ports. Layer 1 forwarding latency is 5 ns, with MetaMux latency of 39 ns and MultiAccess latency of 55 ns. The FPGA has 32GB of DDR memory, and a quad-core x86 CPU with 8GB RAM and a 64GB onboard SSD runs the Linux-based platform. This SKU has rear-to-front airflow and two AC power supplies, with a maximum power draw of 430W.

The SFP+ ports accept 10GBASE-CR, SRL, SR, LRL, LR, ER and DWDM optics, along with 40GBASE-CR4 breakout cabling. FPGA applications are developed with the FDK and Vitis Dev Kit, and the switch also has PPS input and output for time synchronisation.

FAQs

Q: What power configuration does this SKU use?
A: It is the 2xAC configuration, with dual hot-swap PWR-500 AC power supplies in a 1+1 redundant arrangement. Maximum power draw is 430W.

Q: What airflow direction does this model have?
A: This -R model has rear-to-front airflow. The matching spare fan module is FAN-7130-1U-R and the spare AC power supply is PWR-500AC-R.

Q: Which optics and cables work in the SFP+ ports?
A: The ports support 10GBASE-CR DAC (0.5 to 5m), SRL, SR, LRL, LR, ER and DWDM optics, plus 40GBASE-CR4 cabling.

Q: Can I run custom applications on the FPGA?
A: Yes. The integrated VU9P-3 FPGA supports Arista and third-party applications, developed using the FDK and Vitis Dev Kit.

Q: How does this model differ from other 7130 variants?
A: This SKU combines 48 SFP+ ports, the VU9P-3 FPGA, an atomic clock, rear-to-front airflow and two AC power supplies.
