Guidelines for sizing a FlexCache volume

Contributors

You must be aware of the limits for FlexCache volumes before you start provisioning the volumes.

The size limit of a FlexVol volume is applicable to an origin volume. The size of a FlexCache volume can be less than or equal to the origin volume. The best practice for the size of a FlexCache volume is to be at least 10 percent of the size of the origin volume.

You must also be aware of the following additional limits on FlexCache volumes:

Limit ONTAP 9.5-9.6 ONTAP 9.7 ONTAP 9.8-9.10.1
