  1. Tier-1 Evolution and Futures GridPP 29, Oxford Ian Collier September 27th 2012

  2. Where are we going?

  3. Where are we going? • Good question

  4. Where are we going? • Good question • We know things are changing

  5. Where are we going? • Good question • We know things are changing • We don’t know how things will turn out

  6. Where are we going? • Good question • We know things are changing • We don’t know how things will turn out • We can make choices

  7. Where are we going? • Good question • We know things are changing • We don’t know how things will turn out • We can make choices • We must be ready to try things and to adapt

  8. Where we are • Services running. • Lots of cores • Lost of disk • Lots of tape • Castor running well & stably • Shaun will talk about storage future • EMI/UMD Middleware rolling out • Continues to be a moving target • Virtualisation • Usage growing fast • Configuration management • Batch & disk farms much more tractable • Deploying new instances of services easier

  9. 2012 • Virtualisation • Heading to most services running on resilient virtualisation platform with shared storage • Unless there is a definite contra-indication (performance) • Currently MS Hyper-V • It works. But it is Windows (unfamiliar territory still) • Likely to migrate to open source solution (ovirt/RHEV) • Cloud • Stratuslabprototype • Continuing EMI/UMD rollout • Focus on EMI-2 • CVMFS Stratum 0 for non-LHC VOs • Ready for testing by VOs

  10. Virtualised hosts Fabric - Tier1 Review, June 2012

  11. 2012 • Combination of Hyper-V and SCD cloud • Deploying new services easier • Testing things much much easier • Combined with Quattor (fabric & configuration management) it is pretty easy to roll out, for example, a test cluster

  12. Getting nebulous • Tier 1 developing SCD Cloud platform • Using StratusLab – integrating cloud & grid • Very much a prototype so far • Several dozen VMs there as well • Very good for ‘just trying things’ • Several use cases: • Internal (Tier1 & SCT) development & testbeds • At present trust users as regular sysadmins • Scientific computing resource for other departments in STFC • Virtualised layer in batch farm • Experiments are investigating clouds • We need to be building up experience • EGI Federated cloud

  13. Looking to Future • Integrating Aquilon • ‘next generation’ configuration database for Quattor • SQL database plus git workflow • Faster more flexible development & deployment • Better relational integrity for the ‘database like’ parts • STFC deploying new DNS management • We will have direct access to manage our networks including API • More dynamic provisioning possible • Entirely more ‘dynamic’ infrastructure? • See cloud work…

  14. Looking to Future • There are emerging themes • Virtualisationmaking hardware provisioning easier • Can abstract hardware delivery/maintenance from service provision • As site admins we like this • Cloud frameworks should allow • containerisation • Users may like this • Within some higher level requirements set by sites users can have much more choice/control of their software environments • More elastic & dynamic access to resources • Cloud interfaces may make access to resources easierfor users

  15. Where are we going? • We know things are changing • We don’t know how it will turn out • We can make choices • Have to be ready to try things and to adapt
