Server virtualization scenario:
The available partition is a logical partition of physical resources (computing, storage, network), which is a collection of user-oriented resources, and its physical network is inter-layered. Generally, the resource clusters in the resource partition are divided into the same available partition according to the following principles. When you distribute your business, you can choose which partitions to use as needed.
All resource clusters in an available partition must originate from a single virtualized environment.
The storage used by all resource clusters in an available partition must be the same.
The DVS used by all resource clusters in an available partition must be the same.
Cloud data center scenario:
Available partitions are the artificial division of computing and storage resources in FusionSphere.
Divide the available partitions, mainly for distinguishing different resource pools in the case of simultaneously accessing multiple virtualized resource pools, and mutual recognition of computing resources and storage resources in the same virtualized resource pool to avoid different virtual The differences between the layers affect the virtual machine.
