# Supported Datastore Types

In relation to HVM Clusters, discussion of storage primarily centers around datastores, which serve as targets for holding virtual machine disks and storing images. Currently, six datastore types are supported with HVM Clusters:

- Directory Pools
- NFS Pools
- GFS2 Pools
- 3Par
- HPE Alletra Block Storage HVM
- HPE Alletra Block Storage Bare Metal

The next several sections will cover Directory Pools, NFS Pools, and GFS2 Pools in detail, including pros and cons of each type, how to configure storage servers, and how to add new datastores through the UI. For more on integrating 3Par servers and HPE Alletra Storage, see the integration guides for those technologies elsewhere in this user manual.
