You must have an understanding of the region and zone in which cloud resources are located before you select a region and zone for a dedicated block storage cluster. For example, you can select the region and zone in which Elastic Compute Service (ECS) instances are located to create a dedicated block storage cluster.
    Cluster Capacity Set the capacity of the dedicated block storage cluster. The following limits apply:
    • Minimum capacity: 61,440 GiB
    • Maximum capacity: 2,359,296 GiB
    • The capacity of each dedicated block storage cluster can be changed by multiples of 12,288 GiB.
    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.
    Dedicated Block Storage Cluster Name Set the name of the dedicated block storage cluster.
    Cluster Performance Type Set the type of the dedicated block storage cluster. You can select Performance or Basic. Take note of the following items:
    • Basic dedicated block storage clusters support enhanced SSDs at performance level 0 (PL0 ESSDs).
    • Performance dedicated block storage clusters support enhanced SSDs at performance level 1 (PL1 ESSDs).
    For more information about ESSDs, see ESSDs.
    Term Set the subscription duration of the dedicated block storage cluster.
  4. Check the configuration fees, read and select ECS Service Terms, and then click Confirm Order.
