Which aggregate type is supported for Flash pool?
You create a Flash Pool aggregate by enabling the feature on an existing 64-bit aggregate composed of HDD RAID groups, and then adding one or more SSD RAID groups to that aggregate. This results in two tiers for that aggregate: an SSD tier and an HDD tier.
What does a flash pool aggregate contain?
A Flash Pool aggregate combines both SSDs and HDDs (performance or capacity) to provide a high-performance aggregate more economically than an SSD aggregate.
What is flash pool in netapp?
The Flash Pool technology enables you to add one or more RAID groups composed of SSDs to an aggregate that consists of RAID groups of HDDs. The HDD RAID groups in a Flash Pool behave the same as HDD RAID groups in a standard aggregate, following the same rules for mixing disk types, sizes, speeds, and checksums.
What are netapp aggregates?
An aggregate is a collection of disks (or partitions) arranged into one or more RAID groups. It is the most basic storage object within ONTAP and is required to allow for the provisioning of space for connected hosts.
How does the Flash Pool technology work NetApp?

How can I configure a Flash Pool aggregate?
You can configure a Flash Pool aggregate by adding one or more allocation units from an SSD storage pool to an existing HDD aggregate. You can assign cache-retention policies to volumes in Flash Pool aggregates to determine how long the volume data remains in the Flash Pool cache.
How does cache retention work in Flash Pool aggregates?
You can assign cache-retention policies to volumes in Flash Pool aggregates to determine how long the volume data remains in the Flash Pool cache. However, in some cases changing the cache-retention policy might not impact the amount of time the volume’s data remains in the cache.
What are the RAID groups for a Flash Pool?
This results in two sets of RAID groups for that aggregate: SSD RAID groups (the SSD cache) and HDD RAID groups. You can configure a Flash Pool aggregate by adding one or more allocation units from an SSD storage pool to an existing HDD aggregate.
