text: **Chapter 6. Storage pools**
  
  This chapter describes how IBM Storwize V7000 manages physical storage resources. All 
  storage resources that are under the system control are managed by using*storage pools*or 
  *MDisk groups*. Storage pools aggregate internal and external capacity and provide the 
  containers in which you can create volumes. Storage pools make it easier to dynamically 
  allocate resources, maximize productivity, and reduce costs. 
  
  You can configure storage pools through the management GUI. Alternatively, you can 
  configure the storage to your own requirements by using the command-line interface (CLI).
