When you create a General-purpose NAS file system, you can purchase a storage plan to deduct resource usage fees. Compared with the pay-as-you-go billing method, storage plans save costs. This topic describes how to purchase, upgrade, and renew a storage plan.

Purchase a storage plan

To purchase a storage plan and deduct the resource usage fees of a General-purpose NAS file system, perform the following steps:
  1. Log on to the NAS console.
  2. In the left-side navigation pane, choose File System > Storage Package.
  3. On the Storage Package page, click Storage Package.
  4. On the NAS Storage Package page, set the required parameters.
    The following table describes the required parameters.
    Parameter Description
    Region The region where the storage plan resides.

    If you attach a storage plan to a General-purpose NAS file system, make sure that the storage plan resides in the same region as the file system.

    File system ID The ID of the file system.

    A storage plan is used to deduct only the fees of the file system to which the storage plan is attached.

    • If you want to create a file system and attach it to the storage plan, select Create file system and bind package from the File System ID drop-down list. For more information, see Create a General-purpose NAS file system.
    • You can also select an existing file system and use the storage plan to deduct the resource usage fees of this file system.
    Deductible Capacity The capacity of the storage plan. Select a capacity based on your business requirements.

    If the used space of the file system exceeds the capacity of the storage plan, the pay-as-you-go billing method is applied. You can also upgrade the capacity of the storage plan. For more information, see Upgrade a storage plan.

    Order Duration The validity period of the storage plan. Select a duration for the storage plan based on your business requirements.

    After the storage plan expires, the pay-as-you-go billing method is applied. You can also renew the storage plan. For more information, see Renew a storage plan.

  5. Click Buy Now, confirm the order, and then complete the payment as prompted.

    Click the file system on the File System List page. The details of the attached storage plan are displayed on the Basic Information page.
