Elastic Compute Service:CreateDedicatedBlockStorageCluster

Last Updated:Sep 25, 2024

Creates a dedicated block storage cluster. When you call this operation, you can specify parameters, such as Azone, Capacity, Type, and PeriodUnit, in the request.

Operation description

Usage notes

  • Dedicated block storage clusters are physically isolated from public block storage clusters. The owner of each dedicated block storage cluster has exclusive access to all resources in the cluster.
  • Disks created in a dedicated block storage cluster can be attached only to Elastic Compute Service (ECS) instances that reside in the same zone as the cluster. Before you create a dedicated block storage cluster, decide the regions and zones in which to deploy your cloud resources.
  • Dedicated block storage clusters are classified into basic and performance types. When you create a dedicated block storage cluster, select a cluster type based on your business requirements.
  • You are charged for creating dedicated block storage clusters.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
