Understanding ACI Hardware and Topologies

Chapter Description

ACI is designed to allow small and large enterprises and service providers to build massively scalable data centers using a relatively small number of very flexible topologies. In this sample chapter from CCNP Data Center Application Centric Infrastructure 300-620 DCACI Official Cert Guide, the author team details the topologies with which an ACI fabric can be built or extended.
