 * Trends
   * 70 percent of data stored on disk has not been accessed in the past 90 days, and is unlikely to be accessed at all in the near future.
     * Would probably be better to store on lower cost storage tiers.
   * Storage Resource Management (SRM) is also a mess, with over 85 percent of clients having serious reporting issues.
     * Even rudimentary "Showback" systems to report back what every individual, group or department were using resulted in significant improvement.
   * Archive is not universally implemented mostly because retention requirements are often misunderstood. This is attributed to lack of collaboration between storage IT personnel, compliance officers, and application owners.
     * A "service catalog" that identifies specific storage and data types can help address many of these concerns.

 * there is no downturn on the demand for storage.
   * To address this:
     1. identify storage inefficiencies.
     1. develop better forecasting methodologies.
     1. implement ILM.
     1. follow vendor management best practices during acquisition and outsourcing. \

Storage Infrastructure Optimization (SIO).

  • Lot of info from https://www.ibm.com/developerworks/mydeveloperworks/blogs/InsideSystemStorage/?order=asc&maxresults=15&sortby=0&page=49&lang=en

  • SIO deals with both the demand and supply of data growth in five specific areas:
    1. Data reclamation, rationalization and planning
    2. Virtualization and tiering
    3. Backup, business continuity and disaster recovery
    4. Storage process and governance
    5. Archive, Retention and Compliance
