Arista 7320X Series Technical Specifications
The Arista 7320X Series modular switches provide industry leading 40/100GbE density and performance. Available as a choice of 8 slot and 4 slot systems they combine wirespeed forwarding with comprehensive L2 and L3 features.
The 7320X Series supports high density layer 2/3/4 wirespeed performance linecards that offer a flexible combination of interface speeds including 10GbE, 25GbE, 40GbE and 100GbE to design large leaf and spine networks for scale-out of east-west traffic patterns with low latency and power efficiency and enable seamless migration from 10/40GbE to 25/100GbE soluitions.
System Performance:
The Arista 7320X systems can be fully populated with up to eight or four linecards respectively
