Configuring storage pools

A storage pool is a logical grouping of Storage Nodes or Archive Nodes. You configure storage pools to determine where object data is stored. You select storage pools that use Storage Nodes when you create Erasure Coding profiles. You select storage pools that use Storage Nodes or Archive Nodes when you configure ILM rules for replication.

Before you begin

Steps

  1. Select ILM > Storage Pools.
  2. Create a storage pool.
    1. Click Insert insert icon at the end of the row for the last storage pool.

      Storage Pools page
    2. Enter a representative name for the storage pool.
      Use a name that will be easy to identify when you configure Erasure Coding profiles and ILM rules.
    3. From the Storage Grade drop-down list, set the type of storage to which object data will be copied if an ILM rule uses this storage pool.
      The values All Disks and Archive Nodes are system-generated.
    4. From the Site drop-down list, set the site to which object data will be copied if an ILM rule uses this storage pool.
      The value All Sites is system-generated.

      When you select a Site, the number of grid nodes and storage capacity information (Installed, Used, and Available) are automatically updated. Make sure that storage pools have sufficient storage and Storage Nodes to support planned ILM rules and the types of copies that will be made.

    5. To add another storage grade/site combination to the storage pool, click Insert insert icon next to Site.
      You cannot create storage pools that include LDR and ARC services in the same storage pool. A storage pool includes either disks or archive media, but not both.
    6. To remove a storage grade/site combination, click Delete delete icon next to Site.
  3. To delete a storage pool, click Delete delete icon next to the storage pool name. You cannot delete a storage pool that is used in a saved ILM rule.
  4. Click Apply Changes.
    Note: Changes made to a storage pool that is currently in use by an ILM policy do not take effect until the ILM policy is reactivated.
