## Advanced features for storage efficiency 

IBM Spectrum Virtualize running inside the IBM Storwize V5000 offers several functions for storage optimization and efficiency. 

This chapter introduces the basic concepts of those functions. It also provides a short technical overview and implementation recommendations. 

For more information about planning and configuration of storage efficiency features, see the following publications. Some of these publications are dedicated to SAN Volume Controller and Storwize V7000, but are still applicable to Storwize V5000 because it uses the same principles:
