Billing for Disks

Billing Items

EVS disks are billed based on the disk type, size, and usage duration.

  • Billing starts: You will be billed for the EVS disks right after you have purchased them, regardless of whether they are attached or not.
  • Billing stops: The billing of a pay-per-use disk stops after it is successfully deleted.

Billing Modes

EVS disks are billed by disk capacity on a pay-per-use basis.

Pay-per-use is a postpaid payment method. Although EVS disks are billed by the second, billing is calculated hourly. If the usage is less than an hour, you are billed based on the actual time consumed.

  • Yearly/Monthly is a prepaid payment method.
  • Pay-per-use is a postpaid payment method. Although EVS disks are billed by the second, billing is calculated hourly. If the usage is less than an hour, you are billed based on the actual time consumed.

Capacity change
  • EVS does not support the reduction of disk capacities.
  • EVS supports the expansion of disk capacities. Additional capacities need to be paid.
    NOTE:

    The expiration time of the EVS disk remains unchanged after the capacity expansion.
  • EVS does not support the reduction of disk capacities.
  • EVS supports the expansion of disk capacities.

Multiple pieces of billing records will be generated within a billing cycle (an hour) when an expansion succeeded.

For example, if you expand the capacity of an EVS disk from 100 GiB to 200 GiB at 01:30:01, two billing records will be generated in the billing cycle from 01:00:00 to 02:00:00. One is the billing record generated for the 100 GiB from 01:00:00-01:30:00, and the other is the billing record generated for the 200 GiB from 01:30:01-02:00:00.

Renewal

You can renew a yearly/monthly disk anytime before it expires or during the retention period.

You can renew your resources on the Renewals page of the management console. For details, see section "Renewal Management" in the Billing Center User Guide.

Overdue Payment

If your account is not topped up after the account balance falls below zero, your account is in arrears and your pay-per-use disk will enter the retention period. For details, see Pay-per-Use Disk Usage Suggestions.

  • During the retention period, if you top up your account, the disk will be unfrozen.
  • During the retention period, if you do not top up your account, the disk will be released after the retention period ends.
