OMC

OMC: Operations Management Center ● Management and coordination for day-to-day operation and service delivery of the Grid infrastructure. ● Defines the operational policy. ● Maintain an operational overview of the Grid. ● Ensuring that problems are being resolved within reasonable time frames and that performance and service delivery targets are being met. ● Maintains a central repository of MW deployed on the infrastructure. А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

OMC: Responsibilities (some…) ● Co-ordinate the activities of the EGEE ROC and CIC; ● Coordinate the definition of the middleware certification and test criteria ● Approve and initiate deployment of successfully tested middleware releases; ● Enable cooperation and access agreements with user communities, virtual organisations and existing national and regional Grid infrastructures; А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

OMC: Responsibilities (some…) ● Promote the development of cross-trust agreements between the various existing Certification Authorities (CAs) operating within the EGEE Grid community and encourage the establishment of new CAs where necessary; ● Maintain a collective overview of network performance and raise any significant issues through the appropriate channels; ● Participate in international bodies establishing standards for the protocols and interfaces involved in Grid operations; А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

ROC

ROC: Regional Operations Center Key role as sources of ● expert advice; ● technical support in the process of building and operating the infrastructure. The ROCs assist the growing number of Resource Centres in joining the infrastructure: ● deployment of MW releases; ● development of procedures and capabilities to operate those resources. А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

ROC: Coordinate and support deployment The ROC ● the first point of contact for each RC ● the intermediary between RCs and the OMC (including coordination of existing national grid infrastructures and how their integrating into EGEE). ● Participate in validating new middleware releases. ● Port middleware to specific regional needs (e.g. local supercomputers etc.) А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

ROC: Coordinate and support operations ● Act as front-line user support ● Act as front-line support for resource centres ● Refer problems to CIC, OMC, or as appropriate А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

CIC

CIC: Core Infrastructure Center The Core Infrastructure Centres (CIC) have two fundamental roles: ● To operate essential grid infrastructure services that are not required at each Resource Centre; ● To act as a Grid Operations Centre providing monitoring and operational troubleshooting services. – In addition they play a crucial role as second-level support to the ROCs for operational problems. А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

CIC: Operate infrastructure services ● VO services: New applications communities joining EGEE negotiate with the OMC and CICs for a CIC to operate services on their behalf: – VO server itself (either LDAP VO server or VOMS service); – may include the registration process web server for the VO. ● Responsibility for managing the VO membership remains with the VO itself (VO manager).

CIC: Operate infrastructure services ● VO-specific services: – Resource Brokers, – database services for replica services for a VO (or set of VOs); – general and, perhaps, VO-specific information services. – User Interface machines (portals) А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

CIC: Act as Grid Operations Centre Monitoring of sites and services, and proactive troubleshooting. Performance monitoring – for example of data transfers, job throughput etc. Metrics and important parameters to be monitored will be developed as part of the CIC program of work. Regularly monitor the accessibility of operational services and resources at Resource Centres and take remedial action as necessary... А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

CIC: operational and support service ● The CICs will eventually provide (between them) a 24x7 operational and support service. ● If a ROC cannot resolve a problem, or – it is a problem with one of the VO services run by a CIC, – problems not related to a specific region the CIC will take responsibility for the problem coordination and resolution. А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC

CIC: Other responsibilities ● Operational configuration management and change control ● Accounting and resource usage/availability monitoring ● Contribute to release notes, guides, etc ● Feedback for infrastructure improvement А.Крюков, А.Демичев, Л.ШамардинФункции и роль Российского CIC
