Creating an Elastic Resource Pool

Precautions

• If you use an enhanced datasource connection, the network segment of the elastic resource pool cannot overlap that of the data source.
• The network segment of an elastic resource pool cannot be changed after being set.

Creating an Elastic Resource Pool

1. In the navigation pane on the left, choose Resources > Resource Pool.
2. On the Resource Pool page, click Buy Resource Pool in the upper right corner.
3. On the displayed page, set the following parameters:

   Table 1 Parameters

   Parameter	Description
   Region	Select a region. Select a region near you to ensure the lowest latency possible.
   Project	Each region corresponds to a project.
   Name	Name of the elastic resource pool. The name can contain only digits, letters, and underscores (_), but cannot contain only digits or start with an underscore (_) or digit. The description can contain a maximum of 128 characters. NOTE: The elastic resource pool name is case-insensitive. Uppercase letters will be automatically converted to lowercase letters.
   CU Range	The maximum and minimum CUs allowed for the elastic resource pool.
   Description	Description of the elastic resource pool
   CIDR Block	The CIDR block to which the elastic resource pool belongs. If you use an enhanced datasource connection, the CIDR block of the elastic resource pool cannot overlap that of the data source. The CIDR block of an elastic resource pool cannot be modified after being set. Recommended CIDR block: 10.0.0.0~10.255.0.0/16~19 172.16.0.0~172.31.0.0/16~19 192.168.0.0~192.168.0.0/16~19
   Enterprise Project	If the created elastic resource pool belongs to an enterprise project, select the enterprise project. An enterprise project facilitates project-level management and grouping of cloud resources and users. NOTE: This parameter is displayed only for users who have enabled the Enterprise Management Service.
   Tags	Tags used to identify cloud resources. A tag includes the tag key and tag value. If you want to use the same tag to identify multiple cloud resources, that is, to select the same tag from the drop-down list box for all services, you are advised to create predefined tags on the Tag Management Service (TMS). NOTE: A maximum of 20 tags can be added. Only one tag value can be added to a tag key. The key name in each resource must be unique. Tag key: Enter a tag key name in the text box. NOTE: A tag key can contain a maximum of 128 characters. Only letters, digits, spaces, and special characters (_.:=+-@) are allowed, but the value cannot start or end with a space or start with _sys_. Tag value: Enter a tag value in the text box. NOTE: A tag value can contain a maximum of 255 characters. Only letters, digits, spaces, and special characters (_.:=+-@) are allowed. The value cannot start or end with a space.
