This paper provides a high-level overview of how data reduction with deduplication and compression work with the Dell Storage Center Operating System (SCOS). Data compression was introduced with SCOS version 6.5.1, and enhancements were added with the SCOS 6.5.10 and 6.7 releases. Data deduplication was introduced with SCOS 7.0, and works in tandem with compression to further reduce the amount of data stored on Dell EMC SC Series arrays.
