Pay-per-Use Billing
Pay-per-use billing means you pay nothing up front and are not tied into any contract or commitment. This section describes the billing rules for pay-per-use SFS file systems.
Application Scenarios
Pay-per-use billing is good for short-term, bursty, or unpredictable workloads that cannot tolerate any interruptions, such as applications for e-commerce flash sales, temporary testing, and scientific computing.
Billed Items
- SFS Capacity-Oriented
Pay-per-use billing is preset by default. You can create an SFS Capacity-Oriented file system for free and pay only for the used storage space based on for how long you use the file system. You will be billed for the file system by the hour, and there is no minimum cost. Any usage period of less than an hour is rounded up to an hour.

- General Purpose File System
Pay-per-use billing is preset by default. You can create a file system for free and pay only for the used storage space based on for how long you use the file system. You will be billed for the file system by the hour, and there is no minimum cost. Any usage period of less than an hour is rounded up to an hour. The read/write traffic is billed based on the actual reads/writes.

- SFS Turbo
Pay-per-use billing is preset by default. You will be billed for the storage capacity based on for how long you use the SFS Turbo file system. The billing starts right after you create a file system. The file system usage is billed by the hour, and any usage period of less than an hour is rounded up to an hour.

Billed Usage Period
The minimum billed usage period of a file system is an hour regardless of when you purchase it. For example, if you purchased a pay-per-use file system at sometime between 18:00:00 to 19:00:00, the usage period of an hour would be billed (18:00:00 to 19:00:00).
Billing Formula
Storage price = Unit price per GB x Storage capacity x Usage period
Write traffic price = Unit price per GB x Write traffic volume
Read traffic price = Unit price per GB x Read traffic volume
- In a lifecycle rule of a general purpose file system, the system presets Transition to Infrequent Access After to 14 days. In this case, you will be billed for 14 days based on the standard storage billing. For the usage after 14 days, you will be billed based on the infrequent access storage billing.
- To obtain the unit price per GB, see the pay-per-use prices on the SFS Pricing Details page.
Billing Examples
Suppose you purchased a 40 MB/s/TiB SFS Turbo file system (500 GB capacity). In a region that charges $0.45 USD/GB-month, you would be billed $225 USD ($0.45 USD/GB-month x 500 GB x 1 month).
Price Change After Specification Change
If you change the specifications of a pay-per-use SFS file system, the original order will become invalid and a new order will be placed. You will be billed based on the new specifications.
If you change file system specifications within a given hour, multiple records will be generated. Different records record the billing for different specifications.
For example, if you purchased a pay-per-use, 40 MB/s/TiB SFS Turbo file system (500 GB capacity) at 09:00:00 and expanded the file system capacity to 600 GB at 09:30:00, the following items would be billed:
- 500 GB file system from 09:00:00 to 09:30:00
- 600 GB file system from 09:30:00 to 10:00:00
Impact of Arrears
Figure 1 shows the statuses a pay-per-use SFS file system can have throughout its lifecycle. After an SFS file system is created, it enters the valid period and works normally during this period. If your account goes into arrears, the file system enters a grace period and then a retention period.
Arrears Reminder
The system will bill you for pay-per-use resources after each billing cycle ends. If your Huawei account goes into arrears, we will notify you by email, SMS, or in-app message.
Arrears Impact
If your account is insufficient to pay your amount due, your account goes into arrears, and your pay-per-use file systems enter a grace period. You are still responsible for expenditures generated during the grace period. You can view the charges on the Billing & Costs > Overview page and pay any past due balance as needed.
If you do not bring your account balance current before the grace period expires, the file systems turn to Frozen and enter a retention period. You cannot perform any operations on pay-per-use file systems in the Frozen status.
If you do not bring your account balance current before the retention period ends, the file systems will be released and the data cannot be restored.
