GRNET Dual Mission The EU e-Infrastructure vision: Integrated Networking + Grid infrastructures GRNET was one of the first NRENs* in Europe adopting the EU e-Infrastructure initiative: Providing both networking and grid infrastructures * NREN: National Research and Education Network Being infrastructure-oriented and application-neutral serving all user eScience communities Expanding its scope to e-Business and e-Government Source: European Commission Unit F3: Research Infrastructures EGI SEE Workshop Athens, 19 April 2006

The GRNET Network Backbone is currently based on 2,5 Gbps leased lambdas Dark fiber has been acquired for 3 network spans (pilot phase) Dark fiber tender for the whole backbone on-going (one offer received) International connectivity 2 * 10 Gbps any day (currently 2* 2,5 Gbps) EGI SEE Workshop Athens, 19 April 2006

The HellasGrid National Grid Initiative HellasGrid Task Force appointed by the Ministry of Economy and Finance at the end of 2002 (MNEC is running the national InfoSoc programme) A strategy group supported by a scientific committee Produced a strategy document The Task Force prepared the National Integration Proposal The HellasGrid MoU was signed at the end of 2003 Pilot Phase (Phase I): 2003-2004 GRNET Pilot Infrastructure installation Isabella site: 64 CPUs, 10 TB SAN, 12 TB Tape Library Participation in EGEE proposal, Coordination of SEE-GRID Consolidation Phase (Phase II): 2004-2006 HellasGrid project implementation Extension of Grid infrastructure (~800 CPUs, 30TB disks, 60TB tape libraries) – (~2 MEuros) Integration in EGEE The HellasGrid MoU was used to form a Joint Research Unit (JRU) GRNET provided a recognition letter by the Ministry after EC request Further application support (~0,5M – 1M Euros) Investigation for further infrastructure support (~1 MEuros) EGI SEE Workshop Athens, 19 April 2006

SEE Europe promoting the NGI/EGI model NGI: National Grid Initiative Infrastructure oriented & application neutral Not driven by applications GRNET acts as an early champion for the SEE area One partner per country since EGEE Phase I! EGEE-SEE and SEE-GRID countries adopted the same model! EGI SEE Workshop Athens, 19 April 2006

Challenges/Experiences/Conclusions Building the HG infrastructure proved difficult Housing, SLAs with local institutes are slow, tedious and expensive! Getting applications /users to exploit the infrastructure is slow! Training/education and dissemination is important Application projects and funding are essential! Received 45 proposals in last Grid-Applications call! Sustainability of the infrastructure and services Equipment will need to be changed after 3-5 years Local “incubators” for GRID technology needed: Experts in local sites Operators should have appropriate mentality (shifts, support) Gained a lot from networking experience (NOCs, NOC-ROC cooperation) Regional, Pan-European and International collaborations are vital Our European friends lead the way: Middleware, VOs, support projects EGI SEE Workshop Athens, 19 April 2006
