FlexVol volumes are one of two formats: 64-bit or 32-bit. A 64-bit volume has a larger maximum size than a 32-bit volume.
A newly created FlexVol volume is the same format as its associated aggregate. However, a volume can be a different format from its associated aggregate in certain cases.
The maximum size of a 64-bit volume is determined by the size of its associated aggregate, which depends on the storage system model.
A 32-bit volume has a maximum size of 16 TB.
