When performing capacity planning for HPE Nimble Storage using deduplication, it's important to understand that deduplication is applied at the pool level and operates on a block size basis. This means that all volumes within a pool benefit from deduplication, and the efficiency of the process depends on the block size and the type of data stored within the pool. Proper capacity planning requires taking into account the pool configuration, block size, and expected deduplication ratios to accurately predict storage savings and performance.
