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

About this task

Storage pools determine where object data is stored. The number of storage pools you need depends on the number of sites in your grid and on the types of copies you want: replicated or erasure-coded.

Guidelines for creating storage pools


  1. Select ILM > Storage Pools.

    The Storage Pools page appears and lists all defined storage pools.

    The list includes the system-default storage pool, All Storage Nodes, which uses the system-default site, All Sites, and the default storage grade, All Storage Nodes.

    Attention: Because the All Storage Nodes storage pool is automatically updated whenever you add new data center sites, using this storage pool in ILM rules is not recommended.
  2. To create a new storage pool, select Create.
    The Create Storage Pool dialog box appears.

  3. Enter a unique name for the storage pool.
    Use a name that will be easy to identify when you configure Erasure Coding profiles and ILM rules.
  4. From the Site drop-down list, select a site for this 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 that will be used if an ILM rule uses this storage pool.
    The default All Storage Nodes storage grade includes all Storage Nodes at the selected site. The default Archive Nodes storage grade includes all Archive 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. If you want to use the storage pool in a multi-site Erasure Coding profile, select insert icon to add an entry for each site to the storage pool.

    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.

    You are warned if you add more than one entry for a site but with different storage grades.

    To remove an entry, select delete icon.
  7. When you are satisfied with your selections, select Save.
    The new storage pool is added to the list.
