Creating a storage pool

You create storage pools to determine where the StorageGRID system stores object data and the type of storage used. Each storage pool includes one or more sites and one or more storage grades.

Before you begin

Steps

  1. Select ILM > Storage Pools.

    The Storage Pools page appears.


    Storage Pools page

    This page lists all defined storage pools, shows the number of Archive Nodes or Storage Nodes in each pool, and specifies whether the storage pool is currently being used in an ILM rule or EC profile. The table below the list shows details for the currently selected storage pool, including the sites in the storage pool and the number and type of nodes at each site.

  2. Click Create.
    The Create Storage Pool page appears. By default, All Sites and the All Storage Nodes storage grade are selected.

    Create Storage Pool modal
  3. Enter a name for the storage pool.
    Use a name that will be easy to identify when you configure Erasure Coding profiles and ILM rules. When you enter the name, the table heading updates automatically.
  4. From the Site drop-down list, select the site to which object data will be copied if an ILM rule or Erasure Coding profile uses this storage pool.
    The default value, All Sites, includes all data center sites in your StorageGRID grid.
    Attention: When creating a storage pool that will be used in an Erasure Coding profile, you must manually add each site you want to include. Do not include the default site, All Sites, in the storage pool.
    When you select a site, the number of Storage Nodes and Archive Nodes in the table are automatically updated.
  5. From the Storage Grade drop-down list, select the type of storage to which object data will be copied if an ILM rule uses this storage pool.
    The All Storage Nodes default value includes all Storage Nodes at the selected site. The Archive Nodes default value includes all Archives Nodes at the selected site. If you created additional storage grades for the Storage Nodes in your grid, they are listed in the drop-down.
  6. Optionally, click insert icon to add another entry to the storage pool.
    For each entry, specify a unique combination of Site and Storage Grade.
    Note: You are prevented from creating duplicate entries or from creating a storage pool that includes both the Archive Nodes storage grade and any storage grade that contains Storage Nodes.
    To remove an entry, click delete icon.
  7. When you are satisfied with your selections, click Save.
    The new storage pool is added to the list.
