Discussion with Joe Little (Stanford University Systems/Network Manager) on: - different deployments of NexentaStor on Stanford's campus - the benefits of choosing NexentaStor for their storage needs - how using OpenStorage can lower storage TCO - new trends in storage Join the Nexenta Webinar Series here: http://www.nexenta.com/corp/events

1. Learn how Stanford University has leveraged Open Storage technology to meet their Storage needs Webinar will start in 10 minutes

2. Learn how Stanford University has leveraged Open Storage technology to meet their Storage needs Webinar will start in 5 minutes

4. Real life experiences - Stanford University

5. Overview - Nexenta Systems

7. Explosion of Unstructured Data structured data unstructured data 80 % of all digital data is unstructured Increasing cost to manage growing storage resources Unstructured data resists categorization, utilization, and reuse

8. Customer Challenges Expensive Fork lift upgrade Trained Administrator

9. Buy More! Getting smart to address the problem Simple to manage Easy to Scale Economics of Scale

10. What is OpenStorage? Freedom of choice at every level of storage stack Innovation and better storage economics

11. OpenStorage represents a growing part of the existing Storage ecosystem. Open storage will account for $10.6B of the $90B Storage market. Source: Oracle Research Paper, March 2010, Get More Storage Efficiency with Sun Storage 7000 Unified Storage Systems

12. Proprietary Disk System Open Storage Server System Storage Software NexentaStor 10X Storage cost Open Source Must buy vendor units Proprietary Head Unit Commodity Hardware Lower cost Lower cost Better selection Must buy vendor controller Controller Hardware Industry Controllers Disks Disks Must buy vendor disk at 5x markup Market price disks

17. How we got here Commercial and non-commercial file servers Tape Backup Data Growth Why buy today when its cheaper tomorrow

18. User Expectations

19. Too Many Choices

20. Disaster Recovery Tape is dead 2nd Tier Storage Commodity growth curve Snapshots

21. The New Backup (Amanda and Crashplan)

22. VMs storage reqs Reliability Performance Snapshot integration

23. 1st Tier Storage Prime Time

24. 1st Tier Setup Get your feet wet with 2nd tier storage HA possible, but at some cost Go through your failure scenarios Expectations may warrant vendor/VAR/SI

25. Storage Growth == Commodity Storage Growth Growth At Stanford

26. Get to the Meat

27. Best Practices Stanford ActiveDirectory is typically non-standard: Use the “gateway” approach NFSv4/Kerberos a work in progress RAID10 is best RAID5/6/Z1/Z2+ for 2nd Tier only More drives > larger drives Sweet spot == 1TB?

28. Evil Practices Hardware RAID

29. First move is to 3rd Parties Third stage is building in-house clouds Second stage is external services leveraging other services (DropBox) Cloud Directions

35. Privately held; HQ in Mountain View with operations in India, Russia, UK, Holland and Germany

36. ZFS optimized filesystem based on Open Storage“Enterprise class storage for everyone”

37. 30,000+ User and 2,000+ Paid customers Customers Resellers Partners 29 29

39. NAS/SAN/iSCSI/FC

40. CDP via ZFS snapshots

41. CDP via block sync

42. Advanced graphics

44. Boot level ZFS

46. performance: variable block size + prefetch

47. Software RAID that identifies and corrects data corruptionZFS checksums not volumes 128 bit

48. Breaking through economic and performance barriers Servers can handle ~1M IOPS Support Flash Storage devices Best Price / Performance sweet spot Less power consumption Simple to maintain and manage Less Expensive than DRAMs

49. Support for Hybrid storage pools Application NexentaStor Write Cache Read Cache High Capacity Storage SSDs HDDs

50. Easy to Scale NexentaStor Increased computational power by adding processors with more CPUs and cache Commodity Hardware Industry Controllers Increase performance using additional SSDs to cache storage reads and writes Disks Expand total capacity by adding disk drive expansion units

52. NFS

53. SCSI

54. iSCSI

55. FC

57. Built in compression

58. De-duplication

59. Data protection
