Billing Examples

Billing Scenario

A user purchased a pay-per-use file system at 15:00:00 on March 18, 2023. The file system specifications are as follows:

• Type: SFS Turbo, 40 MB/s/TiB
• Capacity: 100 GB

After a period of time, the user found that the current file system specifications no longer met service requirements and expanded the file system capacity to 200 GB at 15:00:00 on March 20, 2023. Since the user wanted to use the file system long term, the user then changed the file system to yearly/monthly billing with a one-month duration at 16:00:00 on March 20, 2023. So how much will the user be billed for this file system in March and April?

Billing Analysis

The total price of this file system involves both pay-per-use and yearly/monthly usage:

• Pay-per-use usage: March 18, 2023, 15:00:00 to March 20, 2023, 16:00:00
• Yearly/monthly usage: March 20, 2023, 16:00:00 to April 20, 2023, 23:59:59

Pay-per-use

• From March 18, 2023, 15:00:00 to March 20, 2023, 15:00:00, the file system capacity was 100 GB and the file system was used for 48 hours, so the price would be $3.02 USD ($0.45 USD/GB-month x 100 GB x 48 hours).
• From March 20, 2023, 15:00:00 to March 20, 2023, 16:00:00, the file system capacity was 200 GB and the file system was used for an hour, so the price would be $0.13 USD ($0.45 USD/GB-month x 200 GB x 1 hour).

Yearly/Monthly

From March 20, 2023, 16:00:00 to April 20, 2023, 23:59:59, the file system was used with yearly/monthly billing for a month, so the price would be calculated as follows:

$0.45 USD/GB-month x 200 GB x 1 month = $90 USD

From March to April, the total price of this file system would be $93.15 USD (3.02 + 0.13 + 90).
