text: The importance of addressing the complexity of managing storage networks is clearly visible 
  in the results of industry analyses of the total cost of ownership (TCO) of storage networks. 
  Typically, storage costs are only about 20% of the TCO. Most of the remaining costs relate to 
  managing storage systems. 
  
  In a non-virtualized storage environment, every system is an “island” that must be managed 
  separately. In large SAN environments, the sheer number of separate and different 
  management interfaces and lack of unified view of the whole environment jeopardizes an 
  organization’s ability to manage their storage as a single entity and to maintain the current 
  view of the system state. 
  
  IBM Storwize V7000, running IBM Spectrum Virtualize software, reduces the number of 
  separate environments that must be managed down to a single system. After the initial 
  configuration of the back-end storage subsystems, all of the day-to-day storage management 
  operations are performed by way of a single graphical user interface. At the same time, 
  administrators gain access to the rich functionality set provided by IBM Spectrum Virtualize, 
  whether particular features are natively available on the virtualized storage systems.
