Use CreateDedicatedBlockStorageCluster to create a dedicated block storage cluster - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Creates a dedicated block storage cluster by calling the CreateDedicatedBlockStorageCluster operation with parameters such as Azone, Capacity, Type, and PeriodUnit.

Operation description

Dedicated Block Storage Cluster is a block storage service that is physically isolated from other public cloud block storage clusters and provides exclusive access to all cluster resources for the owner.
Cloud disks created on a dedicated block storage cluster can be attached only to ECS instances in the same zone. Before you create a dedicated block storage cluster, plan the region and zone for the resources.
Dedicated block storage clusters are classified into basic and performance types. Select the appropriate cluster performance type based on your business requirements when you create a cluster.
You are charged for creating a dedicated block storage cluster.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
