Manage cloud host storage

Storage types are used to classify storage pool resources. Each storage type can contain one or more storage pools. For a cloud host, its storage volumes are hosted by the storage pools of the specified storage type for the cloud host.

The system provides a common storage type by default and assigns storage pools for cloud hosts of the storage type randomly. To assign a specific storage pool to cloud hosts, create a storage type for the storage pool, and then create S-flavors and M-flavors by using the storage type. For more information about creating S-flavors and M-flavors, see "Manage cloud host flavors."

Restrictions and guidelines

• If the CAS virtualization platform is used, make sure all CVK VMs are mounted with the same shared storage pool and have the same local storage pool name.

• If the VMware virtualization platform is used, make sure all ESXi VMs are mounted with the same shared storage pool and have the same local storage pool name.

• VMware requires storage volumes to use different names.

• When the storage type is local file system, the maximum and available storage spaces represent only the local storage conditions of a host. They do not represent the local storage conditions of all hosts.
