System Disk Billing Method

The 40 GB free gift policy of the cloud compute CDS system disk will be cancelled from April 8, 2020. If you have purchased a postpaid cloud compute, the 40 GB free complimentary capacity of the postpaid CDS system disk included in it can still be used normally, but from April 8, the occupied capacity will be charged at the CDS catalog price corresponding to the corresponding disk type. The prepaid CDS system disk is not within the scope of this price adjustment, but it will still be affected when you initiate an expired renewal or allocation operation. The detailed changes in this price adjustment are as follows:

However, if you renew the prepaid cloud compute after expiration, the CDS system disk contained in it will no longer be given 40GB capacity for free; if you initiate operations such as expansion and configuration changes to the prepaid CDS system disk contained in the prepaid cloud compute, the initiated change orders will no longer be given 40GB capacity for free;
• For the prepaid and postpaid cloud compute BCC (architecture including x86 computing and heterogeneous computing GPU) purchased after this adjustment, the CDS system disks included in it are no longer free of 40GB capacity.

The purchase methods affected by this billing adjustment include:

• CDS system disk included in the cloud compute BCC (architecture including x86 computing and heterogeneous computing GPU) that you purchase directly through the console or API;
