This topic describes the billable item, billing methods, and related prices of Cloud Paralleled File System (CPFS) file systems.

Billable item

CPFS file systems are billed based on the storage capacity. In other words, you are charged for the storage that you use.

For example, Mr. Wang purchased a CPFS file system in the China (Hangzhou) region. The capacity of the file system is 3.6 TiB. The subscription billing method is selected and the subscription length is one month. The following formula shows how the total fee is calculated.

Total fee = 3.6 TiB × 1,000 × CNY 1.26 per month per GiB = CNY 4536

Billing methods

CPFS supports the subscription and pay-as-you-go billing methods.

  • Pay-as-you-go: You are charged based on the storage capacity of your file system. The billing cycle is one hour. The fees incurred within an hour are deducted from your account balance in the next hour. For example, if the current time is 9:30, the current hourly bill includes the fees that are incurred from 8:00 to 9:00.
  • Subscription: You can use the subscription billing method to purchase resource plans in advance. The fees incurred by resource usage are deducted from the purchased resource plans. In most cases, the subscription billing method is more cost-effective than the pay-as-you-go billing method. You can set the subscription length to one month, two months, three months, six months, or one year. The longer the subscription length, the more favorable the price.
    Note You must renew your subscription before it expires. Otherwise, the file system will become unavailable. If you renew your subscription within seven days after the file system becomes unavailable, the file system becomes available again. Otherwise, the file system will be automatically released seven days later.
