8
UK DTI Mission – 29 June 2004 - 8 The LCG Deployment Board Grid Deployment Board (GDB) set up to address policy issues requiring agreement and negotiation between resource centres Members: country representatives, applications, and project managers Sets up working groups Short term or ongoing Bring in technical experts to focus on specific issues GDB approves recommendations from working groups Groups: Several that outlined initial project directions (operations, security, resources, support) Security – standing group – covers many policy issues Grid Operations Centre task force User Support group Storage management and other focused issues Service challenges

UK DTI Mission – 29 June 2004 - 9 Operations services for LCG Operational support Hierarchical model CERN acts as 1 st level support for the Tier 1 centres Tier 1 centres provide 1 st level support for associated Tier 2s Grid Operations Centres (GOC) Provide operational monitoring, troubleshooting, coordination of incident response, etc. RAL (UK) led sub-project to prototype a GOC 2 nd GOC in Taipei now in operation –Together providing 16hr coverage –Expect 3 rd centre in Canada/US to help achieve 24hr coverage User support Central model FZK provides user support portal –Problem tracking system web-based and available to all LCG participants Experiments provide triage of problems CERN team provide in-depth support and support for integration of experiment sw with grid middleware
10
UK DTI Mission – 29 June 2004 - 10 Security LCG Security Group (led by Dave Kelsey (RAL) LCG usage rules – proposed as general Grid usage guidelines Registration procedures and VO management Agreement to collect only minimal amount of personal data Currently registration is only valid for 6 month (procedures will change) Initial audit requirements are defined Initial incident response procedures Site security contacts etc. are defined Set of trusted CAs (including Fermilab online KCA) Security policy (to be finished by end of year) This group is now a Joint Security group covering several grid projects/infrastructure

UK DTI Mission – 29 June 2004 - 13 Grid Operations Management Structure
14
UK DTI Mission – 29 June 2004 - 14 LCG and EGEE Operations EGEE is funded to operate and support a research grid infrastructure in Europe The core infrastructure of the LCG and EGEE grids will be operated as a single service, will grow out of LCG service LCG includes US and Asia, EGEE includes other sciences Substantial part of infrastructure common to both LCG Deployment Manager is the EGEE Operations Manager CERN team (Operations Management Centre) provides coordination, management, and 2 nd level support Support activities are expanded with the provision of Core Infrastructure Centres (CIC) (4) Regional Operations Centres (ROC) (9) ROCs will be coordinated by Italy, outside of CERN (which has no ROC)
15
UK DTI Mission – 29 June 2004 - 15 LCG EGEE Operational support: The LCG GOC is the model for the EGEE CICs CIC’s replace the European GOC at RAL Also run essential infrastructure services Provide support for other (non-LHC) applications Provide 2 nd level support to ROCs User support: Becomes hierarchical Through the Regional Operations Centres (ROC) Act as front-line support for user and operations issues Provide local knowledge and adaptations Coordination: At CERN (Operations Management Centre) and CIC for HEP
16
UK DTI Mission – 29 June 2004 - 16 Policy
17
UK DTI Mission – 29 June 2004 - 17 LCG Security and Availability Policy Prepared jointly with GOC group Objectives Agreed set of statements Attitude of the project towards security and availability Authority for defined actions Responsibilities on individuals and bodies Promote the LHC science mission Control of resources and protection from abuse Minimise disruption to science Obligations to other network (inter- and intra- nets) users Broad scope: not just hacking Maximise availability and integrity of services and data Resources, Users, Administrators, Developers (systems and applications), and VOs Does NOT override local policies Procedures, rules, guides etc contained in separate documents
18
UK DTI Mission – 29 June 2004 - 18 Resource access policy Resource negotiation Each participating site might have constraints – funding policy, levels of support, user communities, etc. Those part of EGEE have committed to provide resources to EGEE applications within those constraints The Operations group together with applications groups, and Regional Operations Centres Negotiate access to resources at sites on behalf of application community Each site might have local access policies – users, applications, etc The grid infrastructure should not override local site policies However, in the context of an EU funded project a commitment to the project may change the policy
19
UK DTI Mission – 29 June 2004 - 19 Approach to SLA’s In LCG: Formal MoU will be made between CERN and the Tier 1 centres for services to the LHC experiments Countries commit to a certain level of resources to be provided In EGEE: A goal of project is to understand what SLA’s mean in a grid framework (we do not know what they are yet): Envisage: SLA between ROC and resource centres in a region –Resources, support levels, backup support, access policies, etc. SLA between regions (via ROC) –Accumulation of individual SLA’s SLAs with network providers Performance against targets will be public information
20
UK DTI Mission – 29 June 2004 - 20 Interoperability Several grid infrastructures for LHC experiments: LCG-2/EGEE, Grid2003/OSG, NorduGrid, other national grids LCG/EGEE explicit goals to interoperate One of LCG service challenges Joint projects on storage elements, file catalogues, VO management, etc. Most are VDT (or at least Globus-based) Grid2003 & LCG use GLUE schema Issues are: File catalogues, information schema, etc at technical level Policy and semantic issues
