Apsara File Storage NAS:Storage plans (no longer available for purchase)

Last Updated:Mar 22, 2024

A storage plan is a type of subscription billing method. You can use a storage plan to offset only the storage usage fees of a file system to which the storage plan is attached. This topic describes how to upgrade and renew General-purpose NAS storage plans.

Note

Alibaba Cloud supports resource plans for Apsara File Storage NAS. You can no longer purchase storage plans. However, you can renew or upgrade existing storage plans. Compared with a storage plan, a resource plan does not need to be attached to a file system. You can purchase multiple resource plans to offset the storage usage fees of multiple file systems.

Usage notes

  • After you purchase a storage plan, NAS offsets fees from the storage plan based on the storage usage of your file system.

  • You can attach only one storage plan to a General-purpose NAS file system. You cannot manually detach the storage plan from the file system. The storage plan is automatically detached only if you delete the file system. You can attach the detached storage plan to another file system of the same storage class in the same region to offset storage usage fees.

  • A storage plan is used to first offset the storage usage fees of the General-purpose NAS file system (Performance, Capacity, or Premium) to which the storage plan is attached. If the storage plan still has a positive balance, the storage plan is used to offset the storage usage fees of the IA storage class based on a specific coefficient.

    • If the following condition is met, the storage plan is sufficient to offset the storage usage fees of the IA storage class: (Capacity of the storage plan - Storage usage of the General-purpose NAS file system) × Coefficient - Storage usage of the IA storage class ≥ 0 GiB.

    • If the following condition is met, the storage plan is insufficient to offset the storage usage fee of the IA storage class: (Capacity of the storage plan - Storage usage of the General-purpose NAS file system) × Coefficient - Storage usage of the IA storage class < 0 GiB. The fees for the excess storage usage are calculated based on the pay-as-you-go billing method.

      The coefficient in the preceding formulas varies based on the storage class of the file system. For Performance NAS file systems, the coefficient is 12.333. For Capacity NAS file systems, the coefficient is 2.333.

Upgrade a storage plan

If the capacity of a storage plan attached to a file system does not meet your business requirements, we recommend that you purchase a resource plan. Compared with a storage plan, a resource plan does not need to be attached to a file system. You can purchase multiple resource plans to offset the storage usage fees of multiple file systems. If you want to upgrade the specifications of an existing storage plan, perform the following steps:

  1. Log on to the NAS console.

  4. Find the storage plan that you want to upgrade and click Upgrade.

    • You can upgrade a storage plan, but you cannot downgrade a storage plan.

    • If you upgrade a storage plan, the file system attached to the storage plan is not affected.

  5. In the Upgrade panel, select a storage capacity. The price of the selected storage capacity appears.

    The capacity of an upgraded storage plan ranges from 500 GiB to 1 PiB.

  6. Confirm your settings, select NAS Storage Package Terms of Service, click Buy Now, and then complete the payment as prompted.

Renew a storage plan

After your storage plan expires, we recommend that you purchase a resource plan. Compared with a storage plan, a resource plan does not need to be attached to a file system.
