ONTAP 9 Manuals ( CA08871-402 )

For business-critical applications that need the lowest possible latency and the highest possible performance, you might create a local tier consisting entirely of SSDs.

To tier data with different access patterns, you can create a hybrid local tier, deploying flash as high-performance cache for a working data set, while using lower-cost HDDs or object storage for less frequently accessed data.

If you need to segregate archived data from active data for regulatory purposes, you can use a local tier consisting of capacity HDDs, or a combination of performance and capacity HDDs.
