CSG: Biggest Storage Challenge 14 “Bootstrapping a funding plan for central storage services where growth is explosive.” Data growth “As Central IT, our biggest challenge is fighting the misconception that storage is ‘cheap.’” Perception of cost “Well by volume it is research data storage and particularly data generated by instruments like telescopes and sequencers.” Research storage June 25, 2010

Possible Next Steps Identify and promote research solutionsBuild central backup serviceBuild, promote archival solutions 15June 25, 2010

Research Storage 16 Low cost Commodity server hardware Inexpensive disks High capacity Scale out capability Service broker vs. provider Partner with existing campus providers June 25, 2010

Central Backup Service Focus on distributed servers Engage potential users Define requirements Identify possible solutions 17June 25, 2010

Archival/Repository Solutions 18June 25, 2010

Next Steps Census Share data with the campus Roadmap Propose future directions Projects Initiate projects according to roadmap Services Roll out new services 19June 25, 2010

Feedback What other data do we need? What changes should ITS make to existing services? What new services should ITS offer? 20June 25, 2010
