Requirements for using Flash Pools

Flash Pools have some configuration requirements that you should be aware of before planning to use them in your storage architecture.

A Flash Pool can use either RAID-DP or RAID4 protection (but not both in the same aggregate).

Flash Pools cannot be used on all platforms. For a list of the platforms that support Flash Pools, see the Hardware Universe.

Flash Pools cannot be used in the following configurations:

•	32-bit aggregates

•	Aggregates that use third-party storage

•	Aggregates that use the ZCS checksum type

•	Aggregates that provide storage to Infinite Volumes

You must either disable the automatic creation of aggregate Snapshot copies or enable the automatic deletion of aggregate Snapshot copies for a Flash Pool. These operations must be done by using the Data ONTAP Command Line Interface. For information about automatic aggregate Snapshot copy creation and deletion, see the Data ONTAP System Administration Guide for Cluster-Mode.

If you create a Flash Pool using an aggregate that was created using Data ONTAP 7.1 or earlier, the volumes associated with that Flash Pool will not support write caching.
