Patent ID: 8918605

Claim:
A method for capacity management in a deduplication computing storage environment by a processor device, comprising: estimating a deduplication storage capacity as a function of an expected deduplication ratio, the expected deduplication ratio being an aggregation of a current deduplication ratio and a configured deduplication ratio, the current deduplication ratio depending on data currently stored in deduplication storage, and the configured deduplication ratio being an estimate made at a configuration stage of the deduplication computing storage environment; wherein estimating the deduplication storage capacity includes estimating S capacity as a function of P capacity , P consumed , R expected , and D nominal , where S capacity is the deduplication storage capacity, P capacity is a physical storage capacity of the deduplication storage environment, P consumed is an amount of physical storage consumed in the deduplication storage environment, R expected is the expected deduplication ratio, and D nominal is a nominal size of data currently stored in the deduplication storage environment.
