You can use System Manager to create storage pools to enable SSDs to be shared by multiple Flash Pool aggregates.
More information
Creating a storage pool
A storage pool is a collection of SSDs (cache disks). You can use System 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 System 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 System 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.
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.
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.
