Huawel OceanStor Pacific series storage supports the volume- or snapshot-based clone feature.

Small storage space occupation: A clone generated by the storage system is not a full physical data copy, which does not occupy large storage space.

Quick generation: The storage system can generate a clone within several seconds to obtain the consistent copy of the source volume data.

Lossless performance: Based on the ROW mechanism, the done write performance is equivalent to the source volume write performance.

Cascading: Clones can be created based on clone volumes or snapshots of clone volumes in the storage system. A maximum of 64 cascading levels are supported.
