Description

The Arista 7130LS Series 48LBAS is a 1U Layer 1+ FPGA switch built for latency-critical environments. It is aimed at trading firms, exchanges, colocation operators and monitoring teams who need deterministic nanosecond-level forwarding, tap aggregation and the ability to run custom FPGA applications on the switch itself.

The switch provides 48 SFP+ ports supporting 100M to 11.3Gbps, plus 2 RJ45 ports, around a Xilinx Virtex UltraScale+ VU9P Speed Grade 3 FPGA with 32GB DDR. An atomic clock is fitted, with PPS input and output ports for time synchronisation. Layer 1 latency is 5 ns, MetaMux is 39 ns and MultiAccess is 55 ns, with jitter under 100 ps. This SKU has front-to-rear airflow, two hot-swap AC power supplies (1+1) and dual hot-swap fan trays, with a maximum power draw of 430W.

Supported Arista applications on this model are MetaWatch, SwitchApp, FDK and VDK. The SFP+ ports accept 10GBASE-CR, SR, LR, ER and DWDM optics as well as 1000BASE-T modules.
