1.6. Data Centers
A data center is the highest level of abstraction in Red Hat Virtualization. A data center contains three types of information:
- Storage
- This includes storage types, storage domains, and connectivity information for storage domains. Storage is defined for a data center, and available to all clusters in the data center. All host clusters within a data center have access to the same storage domains.
- Logical networks
- This includes details such as network addresses, VLAN tags and STP support. You can define logical networks for a data center and apply them to clusters.
- Clusters
- Clusters are groups of hosts with compatible processor cores, either AMD or Intel processors. Clusters are migration domains; virtual machines can be live-migrated to any host within a cluster, and not to other clusters. One data center can hold multiple clusters, and each cluster can contain multiple hosts.
