Arista 7500R Series Technical Architecture


The Arista 7500R Series is designed with the latest in switching silicon and software.

The Arista 7500 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 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.

 

7500R Architecture Advantages:

 

  • Investment protection - backward and forward line card compatibility
  • Consistent 7500 Series architecture ensures seamless migrations
  • Distributed packet processor scales forwarding capacity linearly
  • FlexRoute technology for Internet route table scale with low power draw
  • System-wide health monitoring
  • Dynamic deep buffers for the most demanding traffic scenarios
  • Virtual Output Queues avoid head of line blocking
  • Cell-based fabric for 100% efficiency and consistent low latency and jitter
  • Fabric N+1 redundancy for no performance degradation
  • QoS Fabric fairness - no hot-spots 

 

 

 

100G MACsec


Bulk data encryption at scale, high performance, and cost-effectively is a major challenge for cloud data centers. The Arista MACsec solution is integrated into a 7500R Series 36 port 100G line card offering high port density and secure performance at an efficient cost point. The 7500R MACsec solution is fully compatible with all other 7500R Series line cards and utilizes proven encryption technology to protect traffic for simple and scalable data center interconnect. In addition to a choice of pluggable 100G optics, it can be used to secure links between tiers in leaf and spine data center designs.

Standards-based IEEE 802.1AE (MAC Security standard, referred to as MACsec) capabilities provide line-rate frame encryption and authentication. This ensures confidentiality as well as providing anti-replay protection and therefore confidence in the integrity of encrypted traffic.
