Manufacturer Overview:
The Arista 7300 Series modular switches are part of the Arista portfolio of datacenter switches. The 7300 Series with 7300X Series line cards increase flexibility andscalability for data center switches supporting both leaf and spine and SplineTMapplications for collapsed end of row and aggregation. The 7300X systems share acommon architecture with the Arista 7050X and 7250X Series and offer a choice oftwo modular systems, a 4-slot and 8-slot that support advanced features fornetwork monitoring, precision timing and network virtualization to deliver scalablehigh performance for software defined cloud networking.
Increased adoption of 10 Gigabit Ethernet servers and applications requiring higherbandwidth is driving rapid adoption of 10 and 40 Gigabit Ethernet switching. The7300 Series support a choice of high density line cards in combination with wirespeed layer 2/3/4 performance that provides a flexible combination of 100M, 1G,10G and 40G switching to design large leaf and spine networks for scale-out ofeast-west traffic patterns with low latency and power efficiency.
With reversible front-to-rear or rear-to-front airflow, redundant and hot swappablesupervisor, power, fabric and cooling modules the system is purpose built for datacenters. The 7300 Series is energy efficient with typical power consumption ofunder 3 watts per 10GbE port for a fully loaded chassis. All of these attributes makethe Arista 7300 Series an ideal platform for building reliable, low latency, resilientand scalable data center networks. Combined with Arista EOS the 7300 Seriesdelivers advanced features for big data, cloud, virtualized and traditional designs.
7300 Supervisor ModuleThe supervisor modules for the 7300 series run Arista Extensible OperatingSystem (EOS) and handle all control plane and management functions of thesystem. One supervisor module is needed to run the system and a secondcan be added for stateful 1+1 redundancy. Each supervisor module takes uponly a half slot resulting in very efficient use of space and a higher densitydesign. The quad-core x86 CPU with 16GB of DRAM and an optional SSDprovides the control plane performance needed to run an advanced datacenter switch scaling to over 1,000 physical ports and thousands of virtualports. A pulse per second clock input port enables synchronizing with anexternal source to improve the accuracy of network timing and monitoringtools.
7300 Fabric and Fan ModuleAt the heart of the 7300 series is the fabric. It interconnects all line cards in a non-blocking architecture irrespective of the traffic pattern providing a full 2.56 Tbps of forwarding to each line card module. Each line card module connects to the fabric with multiple links and flows are spread across these paths to efficiently utilize the available fabric capacity. The fabric modules are always active-active, providing high availability and can be hot-swapped with graceful performance degradation.
The fabric modules for the two chassis are different based on the size of the chassis and each accommodate a set of individual hot-swap fan modules. The fan modules support forward and reverse airflow and provide redundant cooling. Each fan module can be independently replaced without any impact of the system.
