Chapter 10. Advanced features for storage 
efficiency
IBM Spectrum Virtualize running inside the IBM Storwize V7000 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.
