The IT industry is at the beginning of two massively disruptive trends: cloud and mobile computing. Distributing computing tools or the ability for a small number of operational personnel to manage tens to hundreds of thousands of servers is one of the major scale forces driving cloud computing economics being leveraged by cloud providers and enterprise IT. In fact, the number of servers per rack has grown from 20 to 40 in 2010 to 60 to 80 in 2013; a trend that will only continue. Along with unparalleled server density increasing, application access via mobile devices is driving massive east-west and north-south data/traffic, thanks to content being distributed across many servers within cloud facilities. From a networking perspective, all this adds up to increased number of higher speed server connections into leaf or Top-of-Rack (ToR) switches and subsequent ToR-to-Core (spine) switch connections with the ability to support ever increasing “Brownian motion” type traffic patterns. High density and performance plus low latency demands are signaling the need for a new generation of 10/40/100 GbE modular switching in private and public cloud infrastructure plus high-end data centers. Enter Arista’s 7500E that’s designed to address the growing need for 10/40/100 GbE switching within demanding virtualized data center environments. In this Lippis Report Research Note, we dive into Arista’s 7500E as it’s a beacon of what’s to come from many other suppliers over the next 18 months.
