  **Performance data collection and IBM Spectrum Control**
  
  Although you can obtain performance statistics in standard .xml files, the use of .xml files is a 
  less practical and more complicated method to analyze the IBM Spectrum Virtualize 
  performance statistics. IBM Spectrum Control is the supported IBM tool to collect and analyze 
  Storwize V7000 performance statistics.
