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

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
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
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
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?
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
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
