Datastores are logical containers, analogous to file systems, that hide specifics of physical storage and provide a uniform model for storing virtual machine files. Datastores can also be used for storing ISO images, virtual machine templates, and floppy images.

Depending on the type of storage you use, datastores can be of the following types:

After creating datastores, you can organize them in different ways. For example, you can group them into folders according to business practices. This allows you to assign the same permissions and alarms on the datastores in the group at one time.

You can also add datastores to datastore clusters. A datastore cluster is a collection of datastores with shared resources and a shared management interface. When you create a datastore cluster, you can use Storage DRS to manage storage resources. For information about datastore clusters, see the vSphere Resource Management documentation.
