Change the tiering policy to automatically re-allocate data from the high-performance primary storage tier to the secondary capacity pool storage tier.

About this task

You can change the tiering policy of a volume at any time. The tiering policy is defined per volume.

Deciding where your data is stored has implications for your cost savings.

FSx for ONTAP has two tiers for storing volume data:

  • SSD storage tier: This primary storage tier is for the data you access most frequently, also known as hot data. Storing data in the primary storage tier is more expensive than in the secondary storage tier.

  • Capacity pool storage tier: This secondary storage tier is for archived data or infrequently accessed data, also known as cold data.

Refer to Managing storage capacity in AWS for FSx for NetApp ONTAP documentation for more information about storage tiers.

Before you begin

Review the four available tiering policies before you change the tiering policy.

  • Auto: Tiers all cold data which includes user data and snapshots to the capacity pool storage tier for a specific time period.

  • Snapshot only: Tiers only snapshot data to the capacity pool storage tier.

  • None: Keeps all your volume's data on the primary storage tier.

  • All: Marks all user data and snapshot data as cold and stores it in the capacity pool storage tier.

Note that some tiering policies have an associated minimum cooling period which sets the time, or cooling days, that user data in a volume must remain inactive for the data to be considered "cold" and moved to the capacity pool storage tier. The cooling period starts when data is written to the disk.
