Supported Flash Pool configurations

Flash Pools enable you to add one or more RAID groups composed of SSDs to an aggregate that is otherwise composed of HDDs. The SSDs function as a high-performance cache for the working data set, increasing the performance of the aggregate without incurring the expense of using SSDs for the entire aggregate.

For more information about the Flash Pool feature, refer to Data ONTAP Storage Management Guide for your version of Data ONTAP.
