Storage pool refers to a logical partition used for storing data. In the same storage cluster, different types of storage pools such as file storage and block storage can be used simultaneously to support different business requirements.

Add a device class

In addition to the storage pool created when configuring distributed storage, additional types of storage pools can also be created.

Note: In the same storage cluster, only one storage pool of file and object storage types can be created, and a maximum of eight storage pools of block storage type can be created.

Procedure of operation

1. In the left navigation bar, click Storage > Open ports.

2. On the Cluster Information tab, scroll down to the Storage Pools section and click Add a device class.

3. Configure the relevant parameters according to the following instructions.

   Parameter	Description
   StorageClasses type	Select the StorageClasses type that is not currently deployed. - File storage: Provides secure, reliable, and scalable shared file storage services. Suitable for file sharing, data backup, and other scenarios. - Block storage: Provides high IOPS and low latency storage services. Suitable for databases, virtualization, and other scenarios. - Object storage: Provides standard S3 interface storage services. Suitable for big data, backup and archiving, and online storage scenarios.
   Number of replicas	The larger the number of replicas, the higher the redundancy and data security, but the storage utilization will also decrease. Usually set to 3 to meet most requirements.
   Device class	Select the added device class in the created storage pool. When selecting a device class, data will be stored in the selected device class. When no device class is selected, data will be randomly stored in all devices in the storage pool.

   If it is an object storage, you can also configure the following parameters:

   Parameter	Description
   Region	Fill in the region where the storage pool is located.
   Gateway Type	Default is S3 and cannot be modified.
   Internal Port	Fill in the port for internal access to the cluster.
   External Access	Enabling/disabling external access will create/destroy a NodePort type Service.
   Instance Count	The number of resource instances for object storage.

4. Click Create。

Create a storage cluster

If a certain type of storage is no longer needed, the storage pool can be deleted after removing the association between the storage pool and StorageClasses.

Procedure of operation

1. In the left navigation bar, click Storage > Open ports.

2. On the Cluster Information tab, scroll down to the Storage Pools section and click the next to the storage pool you want to delete, then select Delete.

3. Read the prompt message and enter the name of the storage pool.

4. Click Delete.

View Object Storage Pool Address

After creating an object storage pool, you can view the internal and external access addresses of the storage pool.

Procedure of operation

1. In the left navigation bar, click Storage > Open ports.

2. On the Cluster Information tab, scroll down to the Storage Pool section and click on the > View Address for the object storage pool.
