In the context of NetApp Cloud Tiering service, what is the default condition for data on an aggregate to be tiered?

The correct condition for data on an aggregate to be tiered in the context of the NetApp Cloud Tiering service is that the used capacity on the aggregate must reach 50% and the data must have satisfied the cooling period of 31 days.

This threshold is crucial because tiering is designed to optimize storage resources by moving less frequently accessed data to lower-cost cloud storage after a specified duration of inactivity. The 50% capacity threshold indicates that the aggregate is becoming moderately full, which prompts the system to consider offloading data to the cloud. The requirement for a cooling period of 31 days ensures that only data that has not been accessed or modified for an extended period is moved, which helps in retaining the most relevant and frequently accessed data on the primary storage system while efficiently utilizing cloud resources for archive purposes.

As a result, these criteria align with storage management best practices by balancing performance needs with cost efficiency in cloud service usage.
