Create a storage pool

Storage pools must contain a minimum of four nodes. The first storage pool that is created is known as the system storage pool because it stores system metadata.

Prerequisites

This operation requires the System Administrator role in ECS.

Steps

  1. In the ECS Portal, select Manage > Storage Pools.
  2. On the Storage Pool Management page, click New Storage Pool.
  3. On the New Storage Pool page, in the Name field, type the storage pool name (for example, StoragePool1).
    NOTE: 
    • A storage pool can only contain HDD nodes or NVMe nodes.
    • Click Drive Technology to list the nodes of the same drive technology.
  4. In the Cold Storage field, specify if this storage pool is Cold Storage. Cold storage contains infrequently accessed data. The ECS data protection scheme for cold storage is optimized to increase storage efficiency. After a storage pool is created, this setting cannot be changed.
    NOTE: Cold storage requires a minimum hardware configuration of six nodes. For more information, see ECS data protection.
  5. From the Available Nodes list, select the nodes to add to the storage pool.
    1. To select nodes one-by-one, click the + icon beside each node.
    2. To select all available nodes, click the + icon at the top of the Available Nodes list.
    3. To narrow the list of available nodes, in the search field, type the public IP address for the node or the host name.
  6. In the Available Capacity Alerting fields, select the applicable available capacity thresholds that will trigger storage pool capacity alerts:
    1. In the Critical field, select 10 %, 15 %, or No Alert.
      For example, if you select 10 %, that means a Critical alert will be triggered when the available storage pool capacity is less than 10 percent.
    2. In the Error field, select 20 %, 25 %, 30 %, or No Alert.
      For example, if you select 25 %, that means an Error alert will be triggered when the available storage pool capacity is less than 25 percent.
    3. In the Warning field, select 30 %, 35 %, 40 %, or No Alert.
      For example, if you select 40 %, that means a Warning alert will be triggered when the available storage pool capacity is less than 40 percent.
    When a capacity alert is generated, a call home alert is also generated that alerts ECS customer support that the ECS system is reaching its capacity limit.
  7. Click Save.
  8. Wait 10 minutes after the storage pool is in the Ready state before you perform other configuration tasks, to allow the storage pool time to initialize.
    If you receive the following error, wait a few more minutes before you attempt any further configuration. Error 7000 (http: 500): An error occurred in the API Service. An error occurred in the API service.Cause: error insertVdcInfo. Virtual Data Center creation failure may occur when Data Services has not completed initialization.
