Managing Storage Pools

A storage pool refers to a logical partition used for storing data. A single storage cluster supports the simultaneous use of different types of storage pools, such as file storage and block storage, to accommodate various business requirements.

Creating a Storage Pool

In addition to the storage pools created during the configuration of distributed storage, you can also create additional types of storage pools.

Tip: Within the same storage cluster, only one file storage and one object storage pool are allowed, while up to eight block storage pools can be created.

Procedure

  1. Access Administrator.

  2. In the left navigation bar, click Storage Management > Distributed Storage.

  3. In the Cluster Information tab, scroll down to the Storage Pool area and click Create Storage Pool.

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

    ParameterDescription
    Storage TypeSelect the currently undeployed storage type.
    - File Storage: Provides secure, reliable, and scalable shared file storage services. Suitable for file sharing, data backup, etc.
    - Block Storage: Provides high IOPS and low latency storage services. Suitable for databases, virtualization, etc.
    - Object Storage: Provides standard S3 interface storage services, suitable for big data, backup archiving, cloud storage services, etc.
    Replica Count
    • When the cluster type is Standard: A higher replica count increases redundancy and data security, but it also reduces storage utilization. Usually, a setting of 3 suffices for most needs.
    • When the cluster type is Extended: The default replica count is 4 and cannot be modified.
    Device Class
    • When the cluster type is Standard: Choose an already added device class within the created storage pool.
      • When selecting a device class, data will be stored in the chosen device class.
      • If no device class is selected, data will be randomly stored in all devices within the storage pool.
    • When the cluster type is Standard: Adding a device class is not supported.

    If it is an object storage type, you can configure the following parameters as well:

    ParameterDescription
    RegionSpecify the region where the storage pool is located.
    Gateway TypeDefaults to S3 and cannot be modified.
    Internal PortSpecify the port for internal access to the cluster.
    External AccessEnabling/disabling external access will create/destroy a NodePort type Service.
    Instance CountNumber of resource instances for object storage.

  5. Click Create.

Deleting a Storage Pool

If a certain type of storage is no longer required, the storage pool can be deleted after dissociating it from the storage class.

Procedure

  1. Access Administrator.

  2. In the left navigation bar, click Storage Management > Distributed Storage.

  3. In the Cluster Information tab, scroll down to the Storage Pool area, click on the ⋮ next to the storage pool you wish to delete > Delete.

  4. Read the prompt information and enter the name of the storage pool.

  5. Click Delete.

Viewing Object Storage Pool Addresses

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

Procedure

  1. Access Administrator.

  2. In the left navigation bar, click Storage Management > Distributed Storage.

  3. In the Cluster Information tab, scroll down to the Storage Pool area, click on the ⋮ next to the object storage pool and select View Address.
