Description
Arista 7500R3 Series Specifications
The Arista 7500R3 Series of modular switches deliver the industry’s highest performance with 230Tbps of system throughput to meet the needs of the largest scale data centers. With a choice of systems the 7500R Series provides four, eight or twelve line card modules, two supervisor modules, and six fabric modules. Designed for continuous operations and with system wide monitoring of hardware and software components, simple serviceability and provisioning to prevent single points of failure the hardware architecture supports high-availability with hot-swap of all components.
Arista 7500R3 Series Architecture
The Arista 7500R3 Series leverages a deep buffer virtual output queue (VOQ) architecture that is 100% efficient, eliminates head-of-line (HOL) blocking and virtually eliminates packet drops even in the most congested network scenarios. An advanced traffic scheduler fairly allocates bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queuing, fixed priority, or hybrid schemes. As a result, the Arista 7500R3 Series can handle the most demanding data center requirements with ease, including mixed traffic loads of real-time, multicast, and storage traffic while still delivering low latency.
7500R3 System Comparisons:
Available in a compact system design, as a choice of 12, 8 and 4 slot, the Arista 7500R3 Series enables a full range of wirespeed ports from 10G to 400G. It lowers total cost of ownership as it is designed to be efficient with power per port as low as 25W per 400G port which combined with front to rear cooling to optimize the data center environment produces the most reliable, dense and power efficient modular switch.
