Effectively run large or campus multi-site enterprises operate transparently as a virtual single deployment that benefit from centralized resources. While autonomous, regional offices still require a high level of redundancy with the same access to advanced features and application services regardless of size. Equally important for large or campus multi-site deployments is the ability to seamlessly expand the network to accommodate new sites or more users while minimizing service disruption and at the same time continuing to efficiently manage the operations.
