  • Economy is forcing the issue for all companies, storage is no exception.Problem is we’re still plagued with the realities defined in a 25 year old axiom: Cost, Performance, Reliability…Pick twoYou can have low price and performance but it’s not reliableYou can have low price and reliability but it’s slowYou can have fast and reliable but its expensive.Reason is that the underlying architecture of storage hasn’t really changed in the past 25 years.It’s become more refined to be sure and it certainly has grown in capacity, but the industry is still limited by 25 year old architecture
  • What it is…
  • Emphasize how our roadmap
  • How is our telemetry better than s.m.a.r.t.

    • 4. Redefining Storage Value Q: Why? … A: Economy!
      The Old Cliché’:
      You can have Performance, Reliability or Cost, Performance, or Low Cost—Pick Any Two!
      Over the past 25 years the storage foundation has been fundamentally unchanged.
    • 5. Redefining Storage Value Q: How?
      Focus on the Fundamentals
      Cost efficiencies
      Performance efficiencies
      Reliability efficiencies
      Intelligent Storage Element (ISE)
    • 6. Redefining Storage ValueStorage Fundamentals
    • 7. Cost Efficiency
    • 8. Redefining Storage ValueCost Efficiency?
      • Conventional RAID done at the drive level
      • 9. Partly due to potential for drive to change location
      • 10. A single component failure in a hard drive results in failure of the entire drive.
      Requires rebuilding data, including empty space, from parity
      • Requires wasted space, power, and cooling in hot spare drives
      Worked fine when drives were small. Today? Not so much.
      Large drives can take days on a busy system!!!
    • 11. Redefining Storage ValueCost Efficiency?
      Conventional SAN vendors typically “hold back” capacity for their own use.
      Can be due to features such as snapshot reserve capacity
      • May be an effort to keep you from getting too close to the end of your physical capacity when “thin provisioning”
      • 12. May be because of current or future software options they want to sell you
      • 13. Might be because performance takes a hit if you fill drives too full
      • 14. “Hold back” ranges from 20%-70% of capacity after RAID
      • 15. Point is, capacity you paid for isn’t available for your use. Good deal if you’re a storage vendor.
    • Redefining Storage ValueReal Cost Efficiency
      ISE is architecturally different!
      Stripes at the drive-head level
      Eliminates “hot-spare drives” in favor of “hot-spare heads.”
      All drives used for data storage
      • DataPac holds 10-3.5” drives or 20-2.5” drives (x2 per ISE)
      • 16. User purchases eight drives, Xiotech adds two drives (16 heads)
      • 17. 8 drive capacity is striped over all 10 drives (80 heads)
      • 18. 20% of each drive is reserved to equal 2 added drives = (16 of 80 heads)
      • 19. Purchased capacity (8 drives) can reach 100% usable capacity (after RAID) without a performance hit partly because 10 physical drives are only 80% full
      • 20. No required “feature holdback” allows ISE to reclaim of 20%-70% wasted space over conventional storage
      • 21. More usable capacity = less cost per usable TB
    • Redefining Storage ValueReal Cost Efficiency Through Web Services
      ICON Manager uses Web Services to manage hardware and interact with applications
      Perform most common storage tasks quickly and accurately using wizards.
      Create volumes and assign them to servers and VMs with just a few clicks – from a single pane.
      All built on open standards
    • 22. Performance Efficiency
    • 23. Redefining Storage ValuePerformance Efficiency?
      Conventional Storage:
      An inverse relationship between performance and drive utilization for most systems
      Performance suffers as drive utilization increases
      Leads to buying more drives to achieve performance target
    • 24. Redefining Storage ValueTrue Performance Efficiency
      ISE utilizes a patented process of striping data.
      One of two methods of striping can be employed
      For extreme performance, active data can be constrained to outer perimeter whereas less active or inactive data retained on inner platter. Drive is 100% full but benefits of “short stroking” are available for active data
      All areas of the platter can be used for all data. Performance stays constant regardless of whether the drive is 1% full or 100% full
      Method used for SPC-1 and SPC-2 benchmarking
    • 25. Each ISE has two Active-Active RAID controllers
      Each ISE has 1GB cache
      Performance scales linearly
      Two ISEs perform twice as fast as one, three, three times as fast, etc.
      6,000 Very Heavy Exchange 2007 users on 20 spindles
      Can be virtualized under Xiotech controllers or numerous third party Virtualized Storage Controllers
      Striping method gives user 10 hard drive spindles for the price of eight

    • 26. Reliability Efficiency
    • 27. Redefining Storage ValueTrue Reliability Efficiency
      ISE monitors Seagate proprietary drive telemetry.If a drive “sneezes” it becomes subject to advanced diagnostics
      The drive may be reset or power cycled multiple times. If that fails to clear the problem:
      Data is copied non-disruptively from each head to other heads in the array
      Once the drive is empty it is subjected to remanufacture process:
      Reload drive firmware
      Refresh Servos and Tracks
      Reformat drive
      Rewrite Servos and Tracks
      If a head or heads are determined to be unsalvageable the head(s) are deactivated, the drive Geometry is reset to a smaller drive, lost capacity is replaced from reserve area.
    • 28. Redefining Storage ValueTrue Reliability Efficiency
      Drive vibration and heat issues have been resolved
      Each drive in the ISE has redundant paths to a backend fabric.
      Fibre Channel Arbitrated Loop has been eliminated in favor of switched fabric.
      • ISE is capable of self-healing drives in place.
      Does not mean it cannot fail.
      Does mean that most common reasons for drive failures can be dealt with without disrupting user environment.
      Result is 114x more reliable than conventional drive enclosure
    • 29. ISE carries the industry’s ONLY five-year
      hardware warranty.
      Xiotech’s exclusive five-year warranty can save tens of thousands of dollars over other storage systems.
      Other vendors also may use shorter warranties and expensive maintenance renewals to force you into a new storage system before you really need it.
      Redefining Storage ValueTrue Reliability Efficiency
    • 30. Storage Value – the Value Equation
      V = C x P x R / $
      Based on public SPC-1 results – not marketing BS
      C = tested capacity in TB
      over which I/O was actually performed – not raw space
      P = measured performance in IOPS
      R = warranty period in years
      $ = tested unit price
