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
    2. Virtualization and tiering
    3. Backup, business continuity and disaster recovery
    4. Storage process and governance
    5. 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.
      2. develop better forecasting methodologies.
      3. implement ILM.
      4. 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,
    2. 10Gb Ethernet,
    3. Solid-State drives (SSD).
