= Storage Infrastructure Optimization (SIO). =
 * Links [[NetworkStorage]]
 * 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
   1. Virtualization and tiering
   1. Backup, business continuity and disaster recovery
   1. Storage process and governance
   1. Archive, Retention and Compliance

 * 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.

== Reshaping Storage for Virtualization and Big Data ==

 * 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. \

 * Other suggestions
   * get upper management to accept new technologies by refering to them as "Green" technologies, as they help reduce energy costs as well.
     * data deduplication.
     * thin provisioning.(drive up storage utilization to rates as high as you dare, typically 60 to 70 percent is what most people are comfortable with.)
     * compression is to refer to them as "Green" technologies, as they help reduce energy costs as well. Thin provisioning can help drive up storage 

 * top three initiatives for 2012 are to implement 
   1. data deduplication, 
   1. 10Gb Ethernet,
   1. Solid-State drives (SSD).
