18 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
/SM590000IBM 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.
/SM590000IBM 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:
/SM590000Fully flexible
/SM590000Bundled (license packages)
The license model is based on a license-per-enclosure concept that is familiar from the first 
generation of IBM Storwize V7000. However, the second generation offers more flexibility to 
match your specific needs.
The conceptual model of the licensing in IBM Storwize V7000 Gen2 and Gen2+ is shown in 
Figure 2-5.
Figure 2-5   Licensing model on IBM Storwize V7000 Gen2 and Gen2+
The base module is represented by IBM Spectrum Virtualize family and is mandatory for 
every controller, enclosure, or externally managed controller unit. Additional licensed features 
can be purchased on-demand as a full software bundle or each feature separately. 
Upgrade: Installing or upgrading the code on the first generation of IBM Storwize V7000 to 
the V8.2 does not change your license model or license needs.
