Guidelines for sizing a FlexCache volume
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 9.8 | ONTAP 9.6 and ONTAP 9.7 | ONTAP 9.5 |
|---|---|---|---|
| Maximum number of FlexCache volumes that you can create from an origin volume | 100 | 10 | 10 |
| Maximum number of origin volumes per node | 100 | 100 | 10 |
| Maximum number of FlexCache volumes per node | 100 | 100 | 10 |
| Maximum number of FlexGroup constituents in a FlexCache volume per node | 800 | 800 | 40 |
