  1. The role of research and education networks in stimulating the demand for NGN Prof. Panayiotis Tsanakas, Chairman of GRNET

  2. GRNET • state-owned company (SA) under GSRT established in 1998 • provide advanced e-infrastructures/services to the Greek academic and research institutions: • National and international connectivity • Infrastructures/services (network, computing, storage) to the community • promotion and dissemination of ICT in the public and private sector

  3. GRNET in numbers: • > 100universities, research centers, academic organizations • >15.000schools • >1.000.000 users • Dark fiber backbone (Nx10 Gbps) • access1 || 10 Gbps per institution • International connectivity through GEANT network 3*10 Gbps • Neutral point for the Greek Internet Exchange (GRIX) node – peering all Greek ISPsat10Gbps each • GRID services • Storage Services • (e.g. Online Storage-Pithos, 50 or 100 GB/user–6500 users per day) • VPS VM provisioning (>400 VMs) & Public Cloud (~okeanos) • 2 DataCenters (NRC& Ministry of Education premises)

  4. 35PoPs 8410kmfibers (IRU) MANs Attiki & Thessaloniki DF loops 33cities Single-mode fiber pair 15-years IRUs Availability >> 99%

  5. GRNET Services • Cloud Computing (Okeanos) • Student IDs • Textbook management (Eudoxus) • Student Internet subscriptions (Diodos) • eVoting (Zeus) • Secure teleconferences (ePresence) • Live webcasting of cultural/scientific events (Diavlos) • GR-IX Operation

  6. GRNET Impact • Massive ICT investments • Facilitation of innovation • Technological testbeds • Increase of broadband and IT take-up • Stimulation of long-term user demand • Cost reduction

  9. Zωντανήμετάδοση και προβολή (webcast) του οπτικοακουστικού περιεχομένου εκδηλώσεων από πολιτιστικούς, εκπαιδευτικούς και ερευνητικούς φορείς

  10. The okeanos approach Ganeti by by • Features: • Production-quality IaaS cloud • Everything open source: • Persistent VMs • Commodity Hardware – No SAN, No exotic network hw • Add plain servers/disks/switches to scale up • Three clicks to start 1 or 10s of VMs, in 15 secs • Simple to operate

  11. Storage: Every file is a collection of blocks Content-based addressing for blocks Partial file transfers, deduplication, efficient syncing Independent of storage backend (NFS, RADOS, …) OpenStack Object Storage API plus extensions An integral part of Synnefo - Single store for Files, VM Images - Uses common backend with Archipelago

  12. main Datacenter (40 racks) • greenarchitecture • PUE <1.6 / 1600KVA • In-row cooling • Fully virtualized • ‘High’ Density (but not too dense…) ~20.000 VMs (20 racks, 1000 VM/rack) • VMs with average 2GB RAM (flavors up to 8 cores &16GB/VM) • QoS in disk/core overcommitment

  13. Cloud Facilities (cont.) Disaster Recovery DC (@procurement stage) Container based solution ‘Louros’ river hydroelectric plant area Up to 320KW Low PUE (<1.3) Outdoor installation (close to hydroelectric plant facility) Water cooling per rack / Freecooling
