Cloud host storage types

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 "Configure cloud host flavors."

Restrictions and guidelines

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

• VMware requires storage volumes to use different names. For example, if local file system datastore exists on both ESX cloud host A and ESX cloud host B, VMware adds (1) to the local file system on ESX VM B to change the name to datastore(1). For such file systems, CloudOS considers that they have the same name. However, if you manually add such a suffix, CloudOS does not identify the name to be the same as the one without the suffix or with an automatically added suffix.

• 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.

Create a storage type

1. On the top navigation bar, click Network, and then select Cloud Hosts from the Compute menu.

2. From the left navigation pane, select Advanced Settings.

3. Select Cloud Host Storage Type.

4. Click Create.

5. Specify storage type parameters as needed and then click OK.

Table-1 Creating a storage type

Parameter	Description
Name	Specify a name for the storage type.
AZ	Specify the AZ. Storage pools of the AZ will be displayed in the Storage Pools area.
Type	Select the file system type. ·          Shared File System—Uses shared storage pools. Local File System—Uses local storage pools on all physical hosts of the compute node.
Storage Pools	Specify storage pools. You can select one or more storage pools.

 

Filter storage types

You can filter storage types by name, description, owner, or AZ.

To filter storage types:

1. On the top navigation bar, click Network, and then select Cloud Hosts from the Compute menu.

2. From the left navigation pane, select Advanced Settings.

3. Select Cloud Host Storage Type.

4. Select a filtering criterion type, and then enter the keyword.

5. Click the search icon .

Delete storage types

1. On the top navigation bar, click Network, and then select Cloud Hosts from the Compute menu.

2. From the left navigation pane, select Advanced Settings.

3. Select Cloud Host Storage Type.

4. Perform either of the following tasks:

• To delete a single storage type, click Delete for the type.

• To delete multiple storage types, select the types, and then click Delete.

5. Click OK.
