1. Software Defined Networks for Dynamic Datacenter and Cloud Environments

2. 2 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. 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. THE SOLUTION

4. Plexxi Ring CALIENT S320 Optical Circuit Switch Fabric Plexxi Switch Ring Packet Switching and Optical Multiplexing Form a flexible layer 1/2/3 network topology that matches application workloads CALIENT S320 Optical Circuit Switch Pure photonic-layer switching Handles high-capacity, on demand traffic flows THE SOLUTION Affinity Driven - SDN Control- Reconfigurable Packet and Circuit Network Server Racks/Clusters

5.

6. 6 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
