Arista EOS

All Arista products including the 7130LBR Series run the same Arista EOS software,

simplifying network administration with a single standard across all switches. Arista

EOS is a modular switch operating system with a unique state sharing architecture

that cleanly separates switch state from protocol processing and application logic.

Built on top of a standard Linux kernel, all EOS processes run in their own protected

memory space and exchange state through an in-memory database. This state

sharing architecture provides the foundation for self-healing resiliency and enables

straightforward third-party development and application integration.

Arista EOS enables advanced monitoring and automation capabilities such as Zero

Touch Provisioning, LANZ, and Linux based tools to be run natively on the switch.

Arista 7130LBR-48S6QD: 48x SFP+, 6 x QSFP-DD ports

Overview

The Arista 7130LBR Series introduces a fully composable architecture for the next

generation of high performance in-network applications. Combining programmable

large-scale FPGAs with a full-featured R3 family switch chip, all connected through

an ultra-low latency layer 1 crosspoint. With native support for 1:N connectivity and

and replication, each front-panel lane can be connected to any combination of two

FPGAs and the switch chip enabling customers to combine multiple applications

and utilise the inherent capabilities of the switching silicon.

Featuring dual Virtex® UltraScale+™ FPGAs, the 7130LBR Series supports two parallel

application instances based on Arista’s LB Board Standard. Arista applications

including MetaMux for low latency multiplexing and MetaWatch for picosecond-

level time stamping can be combined with third party applications and custom

functionality developed with the EOS FPGA Development Kit (FDK). The FDK builds

upon EOS’s extensible architecture and includes example code and IP cores to

accelerate new projects.

The 7130LBR Series includes an R3 generation switch element supporting line-rate

L2/L3 forwarding and a complete set of advanced routing features. Using the layer 1

crosspoint, these switch ports can be exibly con gured in-band or out-of-band. In-

band ports enable high-bandwidth switching & routing capability, and out-of-band

ports provide rich streaming telemetry, o oading FPGA resources. The switch can

also be con gured in tap aggregation mode, leveraging the Arista DANZ feature set.

The 7130LBR is available in a space-saving 1RU form factor with 48 x SFP+ and 6 x

QSFP-DD interfaces (NRZ). Each QSFP-DD interface may be broken out to 2 x 40GbE

or 8 x 10GbE interfaces, for a total of 96 x 10G lanes.
