Overview

Exchanges and traders today tend to do everything possible to shave every

nanosecond of latency from the network. FPGA-based applications and Layer 1 X-

Point connectivity provide blazing fast data distribution, critical to achieving the

lowest possible latency. With increasing volatility and market data volume spiking

bursts of traffic, upgrading the speed of the network infrastructure becomes an

obvious choice to adapt to rapidly changing market events. The lack of higher

speed infrastructure in ultra low latency networks has inhibited HFT venues from

performing network upgrades. The Arista 7135LB Series FPGA-enabled devices

leverage FPGA technology and a 25G crosspoint matrix switch to enable the

development and deployment of cutting-edge network applications. With 48

SFP28 ports and 4 QSFP28 ports, the platform supports the next generation of

25G+ ultra low latency applications, featuring a Xilinx UltraScale+ FPGA. The 7135LB

adds a Layer 1 crosspoint fabric between the FPGA and front-panel, supporting 25G

replication at only 5ns.

The Xilinx UltraScale+ FPGA allows customers to run either the applications

developed by Arista, or to develop their own custom applications. On top of

market-leading FPGA functionality, 7135LB Series combines a range of Layer 1+

network functionality such as signal regeneration, port mirroring, dynamic

patching/link management, ad-hoc tapping without rewiring, and media

conversion telemetry and more, all in one device.

Arista 7135LB Series

Feature

Benefits

Simplified stack

Fan-out with 5 ns of latency, equivalent to a single meter of

fiber or copper interconnect and insignificant jitter.

Media conversion

Reduces costs by converting between different media types

running at the same rate

Layer 1+ functionality

Save rack space and reduce complexity by leveraging dynamic

patching, tapping, one-to-many replication, telemetry and

comprehensive port statistics on a single device.

Feature rich

Avoid the need to build features in-house by leveraging Arista’s

access control, syslog, SNMP, packet stats, tcpdump, JSON RPC

API, time series data, streaming telemetry and more - included

as standard within the 7135 Series.

Easy app deployment

Streamline operational processes through Arista’s built-in

application infrastructure which allows developers to wrap

applications into simple packages for deployment.

Enterprise ready

Deploy FPGA applications with ease - the FPGA platform

integrates with a 64-bit x86 management processor and the

MOS and/or EOS Operating systems to provide user extensible

solutions.
