Storage pools

You can use Storage Manager to create storage pools to enable SSDs to be shared by multiple Flash Pool aggregates .

  • 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.
  • Adding disks to a storage pool
    You can add SSDs to an existing storage pool and increase its cache size by using Storage Manager .
  • Deleting storage pools
    You might want to delete a storage pool when the cache of the storage pool is not optimal or when it is no longer used by any aggregate or Flash Pool aggregate . You can delete a storage pool by using the Delete Storage Pool dialog box in Storage Manager .
  • How to use SSD storage pools
    To enable SSDs to be shared by multiple Flash Pool aggregates, you can add the SSDs to a storage pool . After you add an SSD to a storage pool, you can no longer manage the SSD as a stand-alone entity. You must use the storage pool to assign or allocate the storage that is provided by the SSD.
  • Requirements and best practices for using SSD storage pools
    Some technologies cannot be combined with Flash Pool aggregates that use SSD storage pools.
  • Considerations for when to use SSD storage pools
    SSD storage pools provide many benefits, but they also introduce some restrictions that you should be aware of when deciding whether to use SSD storage pools or dedicated SSDs.
  • Considerations for adding SSDs to an existing storage pool versus creating a new one
    You can increase the size of your SSD cache in two ways—by adding SSDs to an existing SSD storage pool or by creating a new SSD storage pool. The best method for you depends on your configuration and plans for the storage.
  • Why you add disks to storage pools
    You can add SSDs to an existing storage pool and increase its cache size. When you add SSDs to a storage pool that has allocation units already allocated to Flash Pool aggregates, you increase the cache size of each of those aggregates and the total cache of the storage pool.
  • How storage pool works
    A storage pool is a collection of SSDs. You can combine SSDs to create a storage pool, which enables you to share the SSDs and SSD spares across multiple Flash Pool aggregates, at the same time.
  • Storage Pools window
    You can use the Storage Pools window to create, display, and manage a dedicated cache of SSDs, also known as storage pools . These storage pools can be associated with a non-root aggregate to provide SSD cache and with a Flash Pool aggregate to increase its size.
