!
7500R Deterministic Network Performance
The Arista 7500 Series uses a deep buffer virtual output queue (VOQ) architecture that 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 queueing, fixed
priority, or hybrid schemes. As a result, the Arista 7500 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.
!

!
Supervisor Module
The supervisor modules for the 7500R series run Arista Extensible Operating System (EOS) and handle all control plane and
management functions of the system. One supervisor module is needed to run the system and a second can be added for stateful 1+1
redundancy. Each supervisor module takes up only a half slot resulting in very efficient use of space and a higher density design. The
multi-core x86 CPU with 32GB of DRAM and an optional SSD provides the control plane performance needed to run an advanced data
center switch scaling to over 1,700 physical ports and thousands of virtual ports. A pulse per second clock input port enables
synchronizing with an external source to improve the accuracy of monitoring tools.
!
Fabric Module
At the heart of the 7500R series is the fabric. It interconnects all line cards in a non-blocking architecture irrespective of the traffic. Each
line card module connects to the fabric with multiple links and data packets are spread across the links to fully utilize the fabric capacity.
Unlike hash-based selection of fabric links, the 7500R architecture provides 100% efficient connectivity from any port to any other port
with no drops. The fabric modules are always active-active, provide N+1 redundancy and can be hot-swapped with zero performance
degradation. The Fabric Modules for the 12-slot, 8-slot and the 4-slot 7500 Series are different based on the size of the chassis and both
integrate a fan assembly for flexible and redundant cooling.
!
Power Supply Modules
The 7500R series switches are equipped with redundant and hot-swappable AC or DC power supplies with an internal variable speed
fan. The 3000W AC power supplies are Titanium climate saver rated and have an efficiency of over 94% with single stage conversion to
the internal 12V DC voltage. 3000W DC power supplies use -40 to -72V direct current inputs.
