Description

The Arista 7130LS Series is a Layer 1+ FPGA switch built for ultra-low-latency trading, market data fan-out and aggregation, network monitoring with precise timestamping, and custom FPGA application development. This 48LAS model carries a Xilinx Virtex UltraScale+ VU7P Speed Grade 2 FPGA and an atomic clock in a 1U chassis.

It provides 48 SFP+ ports supporting 100M to 11.3Gbps, plus 2 RJ45 ports. Layer 1 latency is 5 ns with jitter under 100 ps, MetaMux latency is 43 ns and MultiAccess latency is 55 ns. The platform has 32GB DDR, 8GB system RAM, a 64GB on-board SSD and a quad-core x86 CPU. This SKU uses front-to-rear airflow with two hot-swap AC power supplies and two hot-swap fan trays, both in 1+1 redundancy, with a maximum power draw of 430W. MetaWatch, MetaMux, MultiAccess, MetaProtect Firewall and ExchangeApp are supported, along with the FPGA Dev Kit.

The SFP+ ports accept 1000BASE-T, 10GBASE-CR, SR, SRL, LR, LRL, ER and DWDM optics, as well as 40GBASE-CR4 cabling. The switch runs Arista MOS and/or EOS.

FAQs

Q: Which Arista FPGA applications does this model support?
A: MetaWatch, MetaMux, MultiAccess, MetaProtect Firewall and ExchangeApp are supported, along with the FPGA Dev Kit. SwitchApp and the Vitis Dev Kit are not supported on this model.

Q: What power supplies does it use?
A: It uses two hot-swap AC power supplies in a 1+1 redundant arrangement, with a maximum power draw of 430W. The 7130-48 models use the PWR-460AC (100-240V AC) power supply, and a DC variant, the PWR-460DC, is also available.

Q: Which optics and cables work in the SFP+ ports?
A: The ports support 1000BASE-T, 10GBASE-CR, SR, SRL, LR, LRL, ER and DWDM optics, as well as 40GBASE-CR4 cabling. Range runs from 0.5m for copper twinax up to 80km for DWDM.

Q: What is the airflow direction on this SKU?
A: This SKU uses front-to-rear airflow, matched by the FAN-7130-1U-F fan module.

Q: Which operating system does it run?
A: It is a Linux-based platform running Arista MOS and/or EOS, with an industry-standard CLI and a JSON RPC API for automation.
