Description

The Arista 7508N is an 8-slot, 13 RU modular chassis switch from the 7500R3 Series of data centre switch routers, built for high-density 400G, 100G and 25G spine and core deployments. It provides 2 supervisor slots, 8 line card slots and 6 fabric module slots, and scales to 153 Tbps and 32 Bpps of throughput with up to 192 x 400G or 768 x 100G ports. This SKU is the bare chassis only, so supervisors, line cards, fabric modules and power supplies are ordered separately.

The chassis supports 7500R3 and 7500R3K line cards with deep packet buffers and a virtual output queue architecture, and is backward compatible with previous 7500R Series components including mixed-mode operation. It offers 8 power supply slots with N+N grid redundancy, 1+1 supervisor redundancy, fabric redundancy and N+1 fan redundancy, with all components hot-swappable and front-to-rear airflow. Arista EOS provides a single binary image with CloudVision, LANZ and ZTP support on an extensible Linux-based platform.
