Assigning disks to existing aggregates

You can increase the size of existing aggregates by adding disks (HDDs or SSDs) or increase the cache for existing Flash Pool aggregates by adding storage pools or dedicated SSDs (cache disks).





  1. Adding capacity disks
    You can increase the size of an existing non-root aggregate or a root aggregate containing disks by adding capacity disks. You can use Storage Manager to add HDDs or SSDs of the selected ONTAP disk type and to modify the RAID group options.
  2. Provisioning cache to aggregates by adding SSDs
    You can use Storage Manager to add storage pools or dedicated SSDs to provision cache by converting an existing non-root HDD aggregate or a root aggregate that does not contain partitioned disks to a Flash Pool aggregate .
  3. Creating a storage pool
    A storage pool is a collection of SSDs (cache disks). You can use Storage Manager to combine SSDs to create a storage pool, which enables you to share the SSDs and SSD spares between an HA pair for allocation to two or more Flash Pool aggregates at the same time.
