Conventional datacenter networks built around monolithic computing silos are far too complex, costly, and rigid for today’s highly dynamic datacenter and cloud environments. The result is unbalanced, underutilized network topologies that increase CAPEX and OPEX costs.

THE PROBLEM

3

What the modern datacenter needs is a fundamentally new networking model.

A flat network architecture that leverages Affinity Driven Networking to fit the physical and packet network to the growing needs of today’s virtual and highly dynamic datacenter and cloud environments.

HOW IT WORKS

An Affinity describes relationships between datacenter resources based on well known tendencies and needs for network end points to communicate with each other

Based on Affinities, Plexxi Control fits network connectivity and topology to optimize application workloads

Driven by Affinity Networking, application workloads get the network they need when they need it

For scaling out datacenters, small and large persistent traffic flows are routed through the hybrid Plexxi switch ring and CALIENT S320 Optical Circuit Switch fabric network
