  25. Enhanced Reliability • Storage controllers implement Proactive Drive Health Monitoring (PFA) • Much more robust implementation when used in addition to the standard SMART technology employed by our competition. • End-to-end error checking on data • Background/Foreground Media Scan – Resolves “Silent” Media Errors • Error-skip algorithm on drive rebuilds. • Multiple concurrent Hot-Spare rebuilds • Striped-mirror implementation of RAID10 (our competitors use mirrored-stripes)

  27. Conclusion: How do we compare? Price – Didn’t discuss, we’re probably slightly more. Performance – Better Flexibility – Better Ease of Use – Better (can provide demo) ROI/TCO – Didn’t discuss, but were better Where’s the “WOW” factor? How about a storage system that’s “Accident Resistant”?

  28. Example #1Customer Accidentally deletes an Array Set (group of logical drives) that contains critical business data.They have no backup of the data (not good)They have no way to recreate the dataWithout data, they will go out of business.

  29. Quote from integrator:Hi Jim:Just wanted to thank your group in Wichita for the great work in recovering the data from the deleted raid array.I wondered if you know if other vendors like HP, EMC or Hitachi can do this type of recovery on the mid range disks systems they sell? It could be a great selling feature to know that the data is recoverable in a disaster situation.It is great selling disk that has so many features that allow it to excel in so many situations.I want to personally thank the development folks for working on this problem over night so we could recover the customers data. Without the recovery the customer was out of business as the disk copy of the data was the only copy of this core data.We had provided advice about backups of the data and they were awaiting the tape units when the deletion of the raidset occurred. Thanks again.CheersTim MatherDirector Systems and Storage Anisoft Group

  30. Example #2Customer Purchases a storage array from a “new” integrator.New integrator installs and starts to configure the new storage array.Array appears to have old configuration on it. Integrator decides to reinitialize (wipe out) old configuration to start from scratch.Customers existing storage array (that the integrator knew nothing about), is wiped clean. Over two Terabytes of production data is gone.

  31. Outcome #2Original integrator received the panic call from the customer.IBM support was notified, and the case was escalated immediately.Third level support was able to interrogate the storage array and recover the original configuration information. The end result was that the customers storage array was restored back to “pre-accident” condition. No data loss.

  32. So What Really Matters? • Diverse drive support • HotScale • Tray Level Intermix • Dynamic Capacity Expansion • Array Migration • Dynamic Cache Allocation • Dynamic Read-Ahead • Dynamic Write-Through • Dynamic Segment Sizing • Dynamic Capacity Expansion • Contiguous Storage Allocation • Flashcopy, VolumeCopy • VSS Provider • SMrepassist Utility • StorageProven with Everybody • Dynamic Features • HotScale • Failover Drivers • Redundant Power/Cooling • RSM Current Customers, we love ‘em. • StorageManager (with Simulators) • SMI-S • SMcli (Source: Gartner’s Data Quest Tele briefing: Assembling the SMB Storage Puzzle, October 2006)
