Abstract
A method is used in managing inline data compression and deduplication in storage systems. A block of data from data stored in a cache of a storage system is identified based on entropy. Entropy of the block of data is compared with a first threshold value. Based on the comparison, the block of data is either deduplicated or compressed without deduplication.
Claims20
A method for use in managing inline data compression and deduplication in storage systems, the method comprising:
- identifying, based on entropy, a block of data from data stored in a cache of a storage system;
- comparing entropy of the block of data with a first threshold value;
- based on the comparison, either deduplicating the block of data or compressing the block of data without deduplication.
A system for use in managing inline data compression and deduplication in storage systems, the system comprising a processor configured to:
- identify, based on entropy, a block of data from data stored in a cache of a storage system;
- compare entropy of the block of data with a first threshold value;
- based on the comparison, either deduplicate the block of data or compress the block of data without deduplication.
