7300 Series | Platform Overview

7300 Chassis - 8-slot and 4-slot

The Arista 7300 chassis provides room for two supervisor modules, four,

or eight line card modules, multiple power supply modules, and four

fabric modules. The 7304 chassis fits into 8 rack units while the 7308

chassis fits into 13U of a standard data center rack. Supervisor and line

card modules plug in from the front, as do power supply modules, while

the fabric and fan modules are inserted from the rear.

The midplane is completely passive and provides control plane

connectivity to each of the fabric and line card modules. The system is

optimized for data center deployments with front-to-rear and rear to

front airflow options.

Line Card Modules

Wire-speed line cards deliver up to 1.92 Billion packets per second of forwarding with a single stage architecture that delivers provides

fair access to all ports. Line cards contains up to 24MB of packet memory that ensures up to 6MB for any single port for lossless

forwarding. Each line card connects to all fabric modules in a non-blocking full mesh and leverages flow based dynamic load balancing

to improve the fabric efficiency by reducing the probability of hash polarization.

The Arista 7300 Series can be populated with any combination of line cards. For environments requiring the highest performance

combined with scalability a range of both copper and fiber options is available addressing dense 1G/10G and 10G/40G with full

support for industry standard connections and comprehensive layer 2 and 3 features for flexible deployment choice.

7300X Architecture

The 7300X Series architecture is designed around an internal clos with line cards and fabric modules fully interconnected to deliver a

low latency fully non-blocking system. Each line card has self contained switch modules and interconnect via the vertical fabric

modules for over 20 Tbps of switching capacity. Dual redundant supervisor modules provide centralized control plane and

management functionality.
