4.2. Networking in Data Centers and Clusters.

Networking within a cluster and a data center refers to objects involved in networking at those levels. Figure 4.1, “Networking within a cluster”. displays data center and cluster networking objects and their connections in Red Hat Enterprise Virtualization.

Cluster level networking objects include:
The listed objects have unique networking properties in Red Hat Enterprise Virtualization and are discussed in detail individually.

4.2.1. Cluster Networking

A data center is a logical grouping of multiple clusters and each cluster is a logical group of multiple hosts. Figure 4.1, “Networking within a cluster”. depicts the contents of a single cluster.
Hosts in a cluster all have access to the same data center storage domains. Hosts in a cluster also have logical networks applied at the cluster level. For a logical network to become operational for use with virtual machines, the network must be defined and implemented for each host in the cluster using the Red Hat Enterprise Virtualization Manager.
