New Data Centre Approved 04/07/2013 Intel Openlab Briefing 3 Data centre in Geneva at the limit of electrical and cooling capacity at 3.5MW New centre chosen in Budapest, Hungary Additional 2.7MW of usable power Local on-site support for hardware maintenance and installations

04/07/2013 Intel Openlab Briefing 4

Good News, Bad News Additional data centre in Budapest now online Increasing users of CERN’s facilities and higher computing requirements as data rates increase Staff numbers are fixed, no more people Materials budget decreasing, no more money Legacy tools are high maintenance and brittle How do we maximise our computing resources within these constraints ? 04/07/2013 Intel Openlab Briefing5

Approach 04/07/2013 Intel Openlab Briefing6 Remodel IT services on Cloud layered models IaaS, PaaS, SaaS Move to commonly used open source tools Focus on strong communities and momentum Implement clouds at scale Aim for 90% infrastructure virtualised Exploit ecosystem solutions rather than writing from scratch

Conclusions CERN IT is re-engineering to deliver additional capacity to 11,000 physicists within fixed resources Clouds models can simplify current large scale computing infrastructure OpenStack and its ecosystem allows us to meet this challenge and help others through open source 04/07/2013 Intel Openlab Briefing20

Questions ? 04/07/2013 Intel Openlab Briefing 21

What have we learnt? Automate everything from the beginning Stackforge community projects are a great help Distributions and appliances make getting started much easier Constant rate of change requires a different approach Focus on core technologies and keep up to date Track new projects but don’t adopt too early unless strategic Many of our users are cloud aware Culture changes for legacy application coding and IT services Communities are major motivators Staff approach needs to change to adapt rather than re-invent 04/07/2013 Intel Openlab Briefing22
