10.3. Cluster Limitations
A cluster is a set of physical hosts that are treated as a resource pool for a set of virtual machines. Hosts in a cluster share the same network infrastructure and the same storage. The cluster is a migration domain within which virtual machines can be moved from host to host. To ensure stability a number of limitations apply to each cluster.
- All managed hypervisors must be in a cluster.
- All managed hypervisors within a cluster must have the same CPU type. Intel and AMD CPUs cannot co-exist within the same cluster.
Note
See Clusters in the Administration Guide for further information about clusters.
