Symmetrical disk geometry

When replicating data with FlexVol volumes, disk geometry is not an issue, unlike replicating data with traditional volumes.

With FlexVol volumes, the symmetry of disk geometry between the source and the destination volumes is less important. It is not necessary that the source and destination volumes have the same number of disks or have disks with identical sizes.

A qtree SnapMirror or SnapVault transfer might fail when the newer version of Data ONTAP on the source system has more number of subdirectories than the supported limit of subdirectories on the destination system running an older version of Data ONTAP.
