Which technology is used in the NetApp Cloud Tiering service?

The correct answer is that the technology utilized in the NetApp Cloud Tiering service is FabricPool. FabricPool is designed to optimize storage management by automatically tiering data from on-premises storage to cloud storage based on data access patterns. This means that less frequently accessed data can be moved to lower-cost cloud storage tiers while keeping more frequently accessed data on faster, local storage.

This tiering process enhances efficiency as it leverages cloud storage effectively, allowing organizations to optimize costs while maintaining performance. FabricPool ensures that while the primary data remains accessible, the overall storage solution becomes more cost-effective and adaptive to workloads.

Other technologies mentioned, such as Flash Pool, FlexGroup, and FlexCache, serve different purposes within the NetApp ecosystem. Flash Pool is focused on integrating SSDs with HDDs to accelerate performance; FlexGroup is designed for scalability by allowing multiple volumes to be presented as a single namespace; and FlexCache is oriented towards caching frequently accessed data across various locations. They do not serve the same purpose as FabricPool in terms of cloud tiering and automated storage management.
