Which NetApp Storage Tier component operates at the aggregate level on a FAS controller?

Which NetApp Storage Tier component operates at the aggregate level on a FAS controller?

• A. Flash Pool
• B. Flash Cache
• C. Flash IO
• D. Flash Disk

Answer: (A)

Flash Pool creates an SSD-based pool tied to a specific aggregate, so it serves as the storage tier for that entire aggregate rather than for a single volume. By placing hot data on the flash pool, all volumes within the aggregate benefit from faster access, while colder data can stay on HDDs. This aggregate-scoped caching is what makes Flash Pool the correct choice here, since it operates at the aggregate level on a FAS controller. Flash Cache, in contrast, is a controller-level cache that can accelerate IO across the system rather than being limited to one aggregate, and the other two terms aren’t standard NetApp storage tier components tied to an aggregate.
