If you want to use the subscription billing method for the storage of your cluster, you must purchase a specific amount of storage capacity when you purchase the cluster.

Scenarios

The total amount of data of the clusters in specific regions under your Alibaba Cloud account is smaller than 10 TB, and the amount of data generated by your business seldom fluctuates.

Limitations

  • The amount of storage capacity that you purchase applies only to a single cluster. This may cause resource waste, because the cluster may consume less storage capacity than the purchased amount.
  • The purchased storage capacity can only be scaled up. Scale-down is not allowed. For more information, see Manually scale up the storage capacity of a cluster.
  • After the purchased storage capacity is exhausted, data can no longer be written to the cluster, which may lead to business interruptions. In this case, you must manually scale up the storage capacity. For more information, see Manually scale up the storage capacity of a cluster.
