Creating cascaded pairs

Fast Snap S-VOLs can be paired with secondary layer S-VOLs. First layer (L1) S-VOLs can also be
paired with secondary layer (L2) S-VOLs. A maximum of 64 layers can be created, and a maximum of
1,024 S-VOLs can be used for a P-VOL. In this case, the snapshot tree is cascaded.

L2 to L64 pairs are called cascaded pairs. The following figure illustrates the configuration of cascaded
snapshot trees.
