Software Defined Networks
for
Dynamic Datacenter and Cloud Environments
THE PROBLEM
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.
2
THE SOLUTION
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
