Storage plan | A storage plan for a General-purpose NAS file system is a subscription billing method. It can be used only to deduct the storage capacity costs of the file system to which it is attached. After a storage plan is attached to a file system, you cannot manually detach it. The storage plan is automatically detached only after the General-purpose NAS file system instance is deleted. If you no longer need a storage plan for a General-purpose NAS file system, you can release the file system after you ensure that the data is backed up or migrated and that your services are not affected. After the resource is released, billing stops. To release the resource, see Delete a file system. Note If a storage plan has expired, you do not need to release the General-purpose NAS file system instance. The storage plan is automatically released upon expiration and can no longer be used. In this case, the General-purpose NAS file system is billed on a pay-as-you-go basis. If you want to continue to receive discounts, we recommend that you Purchase resource plans. Compared with storage plans, resource plans do not need to be attached to a file system. They can be used to deduct the storage capacity costs of multiple General-purpose NAS file systems and can be stacked. | If you want to switch the billing method before the storage plan expires, please submit a ticket to proceed. |
Unsubscribing from a subscription Extreme NAS file system resource, deleting a pay-as-you-go file system instance, or deleting a file system instance to which a storage plan is attached releases the file system instance.
