Creating a dedicated block storage cluster grants you exclusive access to the storage resources within the cluster. This topic describes how to create a dedicated block storage cluster.

Prerequisites

To use a dedicated block storage cluster for the first time, you must submit a ticket to apply for the feature.

Background information

Note

Dedicated Block Storage Cluster is currently available in the following regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Heyuan), Indonesia (Jakarta), Germany (Frankfurt), and China South 1 Finance.

When you create a dedicated block storage cluster, note the following:

  • When you log on to the Elastic Block Storage console for the first time, follow the on-screen instructions to create an EBS service-linked role. For more information, see Service-linked roles for EBS.

  • Dedicated block storage clusters are available in two performance types: Basic and Performance. Select a type based on your business requirements when you create a cluster.

  • Creating a dedicated block storage cluster incurs charges. For more information, see Billing.

Procedure

  1. Go to the dedicated block storage clusters page.

    1. Log on to the Elastic Block Storage console.

    2. In the left-side navigation pane, choose Enterprise-level Features > Dedicated Block Storage Cluster.

  2. In the top navigation bar, select the region and resource group of the resource that you want to manage. Region

    Parameter

    Description

    Billing Method

    Dedicated block storage clusters support only the Subscription billing method.

    Region and availability zone

    Select the region and availability zone for the dedicated block storage cluster.

    Note

    You cannot change the region or availability zone after the cluster is created. Plan the region and availability zone for your cloud resources in advance. For example, when you create a dedicated block storage cluster, set its region and availability zone to match those of your other resources, such as ECS instances.

    Cluster Capacity

    Set the cluster capacity. The capacity range and adjustment increments 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).

    Note

    If 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

    Enter a name for the cluster to help you identify and manage it.

    Cluster Performance Type

    Select a performance type for the cluster. You can select Basic or Performance. The following list describes the types:

    • Basic: This cluster type can only create ESSD PL0 disks.

    • Performance: This cluster type can only create ESSD PL1 disks.

    For more information about ESSDs, see ESSDs.

    Duration

    Select the subscription duration for the cluster.

    Service-linked Role
