Description

The Arista 7130LS Series 48-port switch is a Layer 1+ FPGA platform built for ultra-low-latency trading, market data distribution and high-precision network monitoring. It combines a Xilinx Virtex UltraScale+ VU7P Speed Grade 2 FPGA with an onboard quad-core x86 server, so Arista, partner or custom applications can run alongside deterministic Layer 1 forwarding.

This SKU provides 48 SFP+ ports supporting 100M to 11.3Gbps, plus 2 x RJ45 ports. Layer 1 forwarding latency is 5 ns, with MetaMux latency of 43 ns and MultiAccess latency of 55 ns. It carries 32GB DDR, 8GB system RAM, a 64GB onboard SSD and an OCXO clock. The 1U chassis uses front-to-rear airflow, with 2 x AC hot-swap power supplies and 2 x hot-swap fan trays, both in 1+1 redundancy, and a maximum power draw of 430W.

The SFP+ ports accept 10GBASE-CR DAC cables, SR, LR, ER and DWDM optics, and 1000BASE-T RJ45 SFP modules. MetaWatch, ExchangeApp, MetaProtect and the FPGA Dev Kit are supported on this model.

FAQs

Q: Which Arista applications does this model support?
A: MetaWatch, ExchangeApp, MetaProtect and the FPGA Dev Kit (FDK) are supported. SwitchApp and the Vitis Dev Kit (VDK) are not supported on the 7130-48LS.

Q: Which optics and cables work in the SFP+ ports?
A: The ports support 10GBASE-CR DAC cables from 0.5m to 5m, plus 10GBASE-SR, LR, ER and DWDM optics and 1000BASE-T RJ45 SFP modules. Genuine SRL and LRL optics are also listed.

Q: What airflow and power configuration is this SKU?
A: It uses front-to-rear airflow with 2 x AC hot-swap power supplies in a 1+1 redundant arrangement. Maximum power draw is 430W.

Q: What spare parts match this airflow direction?
A: The matching spare fan module is FAN-7130-1U-F. Matching spare power supplies are PWR-500AC-F (AC) and PWR-500-DC-F (DC).

Q: What is the Layer 1 forwarding latency?
A: Layer 1 forwarding latency is 5 ns. MetaMux adds 43 ns and MultiAccess 55 ns.
