Storage plan | A General-purpose NAS 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. You cannot manually detach the storage plan from the file system. However, if you delete the General-purpose NAS file system, the storage plan is automatically detached. If you no longer use a General-purpose NAS storage plan, you can release the General-purpose NAS file system.

After the storage plan expires, you are charged for the General-purpose NAS file system based on the pay-as-you-go billing method. If you want to continue to enjoy discounts, we recommend that you purchase resource 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 General-purpose NAS file systems. | If you want to change the billing method before the storage plan expires, contact NAS technical support. |
If you unsubscribe from a subscription Extreme NAS file system, delete a pay-as-you-go file system, or delete a file system to which a storage plan is attached, the file system is released. After the NAS file system is released, if requests are still initiated to access the NAS file system, the NAS file system cannot be properly accessed. Therefore, before you unsubscribe from a subscription NAS file system or delete a pay-as-you-go NAS file system, you must back up or migrate the data of the file system.
