The document summarizes a webinar about redefining storage value through a business-savvy storage strategy. It discusses how the Intelligent Storage Element (ISE) architecture provides cost efficiency by eliminating hot spare drives and maximizing usable capacity. It provides performance efficiency through striping at the drive-head level to maintain consistent performance regardless of utilization. It ensures reliability efficiency by monitoring drive telemetry and replacing failed drive heads instead of entire drives to reduce downtime. The ISE approach aims to optimize capacity, performance, and reliability for the lowest overall cost.

4. Redefining Storage Value Q: Why? … A: Economy!Q:A: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.

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 parityRequires wasted space, power, and cooling in hot spare drivesWorked 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 capacityMay 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 EfficiencyISE is architecturally different!Stripes at the drive-head levelEliminates “hot-spare drives” in favor of “hot-spare heads.”All drives used for data storageDataPac 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
