Description
Billing Method
Dedicated block storage clusters support only the Subscription billing method.
Region and Zone
Set the region and zone for the dedicated block storage cluster.
NoteYou cannot change the region and zone of a cluster after it is created. Plan the region and zone for your cloud resources in advance. For example, when you create a dedicated block storage cluster, set its region and zone to be the same as those of your resources, such as ECS instances.
Cluster Capacity
Set the capacity of the cluster. The capacity range and adjustment limits are as follows:
Minimum capacity: 60 TiB (61,440 GiB)
Maximum capacity: 2,280 TiB (2,334,720 GiB)
Capacity adjustment increment: You can adjust the capacity only in increments of 12 TiB (12,288 GiB).
NoteIf the capacity of a dedicated block storage cluster is less than 576 TiB, the maximum throughput per TiB cannot exceed 52 MB/s. If the capacity of a dedicated block storage cluster is greater than 576 TiB, the maximum throughput per TiB cannot exceed 26 MB/s.
Dedicated Block Storage Cluster Name
Set a name for the cluster to make it easier to manage.
Cluster Performance Type
Set the performance type of the cluster. You can select Basic or Performance. The types are described as follows:
Basic dedicated block storage clusters can be used to create only PL0 ESSDs.
Performance dedicated block storage clusters can be used to create only PL1 ESSDs.
For more information about ESSDs, see ESSDs.
Duration
