text: (cid:2) IBM Easy Tier 
  
  Provides a mechanism to seamlessly migrate hot spots to the most appropriate tier 
  within the IBM Storwize V7000 solution. This migration can be to internal drives within the 
  IBM Storwize V7000 or to external storage systems that are virtualized by IBM Storwize 
  V7000. Independently on Easy Tier, IBM Storwize V7000 provides an automatic storage 
  pool balancing that is enabled by default and requires no license. 
  
  (cid:2) IBM Real-time Compression 
  
  IBM Real-time Compression technology is based on the Random Access Compression 
  Engine (RACE). RACE is a part of the software stack of IBM Spectrum Virtualize V6.4 and 
  later. This integration does not alter the behavior of the system, so previously features are 
  supported for compressed volumes. Starting with IBM Spectrum Virtualize V7.6, two 
  software-enabled RACE engines sharing HW resources for compression are required. 
  
  **2.3.4 IBM Storwize V7000 licensing**
  
  With the broad range of technical features and capabilities of the IBM Storwize V7000 Gen2 
  and Gen2+, including Copy Services, External Virtualization, Easy Tier, and Real-time 
  Compression, IBM simplified the licensing model to include these new features. The IBM 
  Storwize V7000 offers two ways of license procurement: 
  
  (cid:2) Fully flexible 
  (cid:2) Bundled (license packages)
