Abstract
Techniques for evaluating deduplication effectiveness of data chunks in a storage system are described herein. In one embodiment, metadata of first data chunks associated with a deduplicated storage system is examined, where the first data chunks have been partitioned according to a first chunk size. A second chunk size is calculated based on the examination of the metadata of first data chunks. Metadata of the first data chunks is merged according to the second chunk size to represent second data chunks to which the first data chunks would have been merged. A deduplication rate of the second data chunks is determined based on the merged metadata.
