Claim 19:
20. A system for partitioning of deduplication domains in storage systems, comprising:
a processor and a memory configured to provide computer program instructions to the processor to execute a function of the following components:
a staging component for providing a staging area for new data chunks including a reference structure of possible deduplication domains into which a new data chunk may be migrated;
a sampling component for carrying out a sampling period for a new data chunk to compare input/output operations for the new data chunk to the reference structure for the deduplication domains,
wherein no deduplications are attempted during the sampling period; and
a domain selection component for selecting a deduplication domain for the new data chunk based on a number of hits to the reference structure indicating deduplication references,
wherein the staging component is a staging storage controller serving input/output operations for a data chunk during the sampling period in which no deduplication takes place,
wherein the possible deduplication domains are each provided by an associated core storage controller having a deduplication database, and the reference structure is populated from the deduplication databases of the core storage controllers.
