CreateDedicatedBlockStorageCluster - Elastic Compute Service

Creates a dedicated block storage cluster.

Operation description

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.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation
ebs:CreateDedicatedBlockStorageCluster	Write	DedicatedBlockStorageCluster acs:ebs:{#regionId}:{#accountId}:dedicatedblockstoragecluster/*	none	none

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The ID of the region in which to create the dedicated block storage cluster. You can call the DescribeRegions operation to query the most recent region list.	cn-heyuan
Azone	string	Yes	The ID of the zone in which to create the dedicated block storage cluster. You can call the DescribeZones operation to query the most recent zone list.	cn-heyuan-b
DbscName	string	Yes	The name of the dedicated block storage cluster.	myDBSCCluster
Capacity	long	Yes	The capacity of the dedicated block storage cluster. Valid values: 61440 to 2334720. Unit: GiB. 2,334,720 GiB is equal to 2,280 TiB. The capacity increases in a minimum increment of 12,288 GB. Note If the capacity of a dedicated block storage cluster is less than 576 TiB, the maximum throughput supported per TiB does not exceed 52 MB/s. If the capacity of a dedicated block storage cluster is greater than 576 TiB, the maximum throughput supported per TiB does not exceed 26 MB/s.	61440
Type	string	Yes	The type of the dedicated block storage cluster. Valid values: Standard: basic type. When you set Type to Standard, enhanced SSDs (ESSDs) at performance level 0 (PL0 ESSDs) can be created in the dedicated block storage cluster. Premium: performance type. When you set Type to Premium, ESSDs at performance level 1 (PL1 ESSDs) can be created in the dedicated block storage cluster. Default value: Premium. For more information about ESSDs, see ESSDs .	Premium
ResourceGroupId	string	No	The ID of the resource group to which to assign the dedicated block storage cluster.	rg-acfmvs*******
Tag	object []	No	The resource tags. You can specify up to 20 tags.
Key	string	Yes	The key of tag N used for exact search of EBS resources. The tag key must be 1 to 128 characters in length. Valid values of N: 1 to 20. The `Tag.N` parameter pair (Tag.N.Key and Tag.N.Value) is used for exact search of EBS resources that have specified tags added. Each tag is a key-value pair. If you specify only `Tag.N.Key`, all EBS resources whose tags contain the specified tag key are returned. If you specify only `Tag.N.Value`, the `InvalidParameter.TagValue` error is returned. If you specify multiple tag key-value pairs at the same time, only EBS resources that match all tag key-value pairs are returned.	tag-key
Value	string	Yes	The value of tag N to add to the resource. Valid values of N: 1 to 20. The tag value can be an empty string. The tag value can be up to 128 characters in length and cannot start with `acs:` or contain `http://` or `https://`.	tag-value
Period	integer	No	The specific number of PeriodUnit.	12
PeriodUnit	string	No	The unit of the subscription duration for the dedicated block storage cluster, Valid values: Month	Month
DbscId`deprecated`	string	No	This parameter is no longer used.	test1233
