11 IBM Real-time Compression This chapter highlights the preferred practices for IBM Real-time Compression that uses IBM  Spectrum Virtualize software installed on IBM SAN Volume Controller, IBM Storwize family,  and IBM FlashSystem V9000. The main goal is to provide compression users with guidelines  and factors to consider to achieve the best performance results and enjoy the compression  savings that the Real-time Compression technology offers. The Real-time Compression  technology is not to be confused with data compression implemented with Data Reduction  Pools (DRP), which is covered in Chapter 3, “Storage pools” on page 81. This chapter assumes that the reader is already familiar with IBM Spectrum Virtualize  Real-time Compression technology. Information on this technology can be found in many  sources, including the following publications: Important:  On 11th February 2020 IBM announced the arrival of SAN Volume Controller  SA2 and SV2, and IBM FlashSystem 7200 to the family.  This book was written specifically for prior versions of SVC and Storwize V7000; however,  most of the general principles still apply.  If you are in any doubt as to their applicability, you should work with your local IBM  representative. This book will be updated to comprehensively include SAN Volume Controller SA2 and  SV2 and FlashSystem 7200 in due course.
