text: Storage can then be deployed from these pools, and migrated transparently between pools 
  without interruption to the attached host systems and their applications. Storage virtualization 
  provides a single set of tools for advanced functions, such as instant copy and remote 
  mirroring solutions, which enables faster and seamless deployment of storage regardless of 
  the underlying hardware. 
  
  Because the storage virtualization represented by IBM Spectrum Virtualize is a 
  software-enabled function, it offers more features that are typically not available on a regular 
  pure storage subsystem, including (but not limited to) the following features: 
  
  (cid:2) Data compression 
  (cid:2) Software and hardware encryption 
  (cid:2) IBM Easy Tier® for workload balancing 
  (cid:2) Thin provisioning 
  (cid:2) Mirroring and copy services 
  (cid:2) Interface to Cloud Service Providers 
  
  Figure 2-2 shows these features.
