Scaling Storage Space

This section describes how to scale storage space of an instance to suit your service requirements.

Precautions

  • Storage space of an instance can be scaled up or down.
  • When you scale down storage space of your instance, make sure that new storage space is 25% more than the used space and rounded up.
  • Scaling up storage does not interrupt your services. After storage scale-up is complete, you do not need to restart your instance.
  • Scaling down storage does not interrupt your services. After storage scale-down is complete, you do not need to restart your instance.
  • If your instance is a yearly/monthly instance and its storage is used up, you will be billed on a pay-per-use basis for any additional storage. Scale up your storage space, and you can pay for the additional storage at yearly/monthly rates.
  • To view storage details on the Instances page, contact customer service.

Procedure

  1. Log in to the GeminiDB console.
  2. In the service list, choose Databases > GeminiDB Cassandra API.
  3. On the Instances page, locate the instance whose storage space you want to scale and choose MoreScale Storage Space in the Operation column.

    Click the instance name. In the Storage Space area on the Basic Information page, click Scale.

  4. On the displayed page, specify a new storage capacity and click Next.

    You must select at least 1 GB each time you scale, and only an integer is allowed.

  5. On the displayed page, confirm the storage space.

    • For yearly/monthly instances
      • If you need to modify your settings, click Previous.
      • If you do not need to modify your settings, click Next and complete the payment.
    • For pay-per-use instances
      • If you need to modify your settings, click Previous.
      • If you do not need to modify your settings, click Submit.

  6. Check the scaling result.

    • When the scaling task is ongoing, the instance status is Scaling storage space.
    • After the scale-up task is complete, the instance status becomes Available.
    • In the Storage Space area on the Basic Information page, check whether the scale-up was successful.
