Creating a Flash Pool aggregate using SSD storage pools

You can configure a Flash Pool aggregate by adding one or more allocation units from an SSD storage pool to an existing HDD aggregate.

More information

Determining whether a Flash Pool aggregate is using an SSD storage pool
You manage Flash Pool aggregates differently when they use SSD storage pools to provide their cache than when they use discrete SSDs.
Creating an SSD storage pool
You can create solid state drive (SSD) storage pools to provide SSD cache for two to four Flash Pool aggregates.
Creating a Flash Pool aggregate using SSD storage pool allocation units
You can configure a Flash Pool aggregate by adding one or more allocation units from an SSD storage pool to an existing HDD aggregate.
Determining the impact to cache size of adding SSDs to an SSD storage pool
If adding SSDs to a storage pool causes your platform model's cache limit to be exceeded, ONTAP does not allocate the newly added capacity to any Flash Pool aggregates. This can result in some or all of the newly added capacity being unavailable for use.
Adding SSDs to an SSD storage pool
When you add solid state drives (SSDs) to an SSD storage pool, you increase the storage pool's physical and usable sizes and allocation unit size. The larger allocation unit size also affects allocation units that have already been allocated to Flash Pool aggregates.
Commands for managing SSD storage pools
ONTAP provides the storage pool command for managing SSD storage pools.
