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:
Bulk data encryption at scale, high performance and cost effectively is a major challenge for cloud data centers. The Arista MACsec solution is integrated to a 7500R Series 36 port 100GbE 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 with 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.
The Arista 100G/200G DWDM solution is integrated to a 7500R Series line card offering high-density with un-compromised performance at an efficient cost point. It utilizes state of the art coherent optical technology to enable simple, reliable and scalable data center interconnect solutions for both metro and long haul applications with flexible support for 100G, 150G and 200G modes.
