A data center is a logical entity that defines the set of resources used in a specific environment. It is a collection of a number of clusters of virtual machines, storage and networks. The data center is the highest level container for all physical and logical resources within a managed virtual environment.
Using the test associated with this layer, you can determine the following:
- The number and names of storage domains, clusters, RHEV servers, and VMs that are managed by every data center on the RHEV manager;
- The disk space resources available to each datacenter, and how well every data center utilizes the space resources - this way, the test accurately points you to data centers that are starved of disk space.
