1 Dr. Ognjen Prnjat European and Regional eInfrastructure management Greek Research and Technology Network on behalf of GRNET Technical department Greek Research and Technology Network: Status and Updates eAge 2012, Dubai

2 GRNET mission GRNET is a state-owned company operating under the supervision of the Ministry of Education (General Secretariat of Research & Technology); non-profit Main mission is to provide high-quality electronic infrastructure services to the Greek academic and research institutions: National and international connectivity services Distributed Computing Infrastructure services (computing, storage, visualisation) Supporting activity is the promotion and dissemination of the use of ICT in the public and private sector towards an e-Government, e- Learning and e-Business environment Main sources of funding are the Operational Programme for the Information Society, Ministry of Economy and Finance and EC projects GRNET has been certified by ISO 9001:2000 in project management

3 Pan-EU e-Infrastructures vision The Research Network infrastructure provides fast interconnection and advanced services among Research and Education institutes of different countries The Research Distributed Computing Infrastructure provides a distributed environment for sharing computing power, storage, instruments and databases through the appropriate software (middleware) in order to solve complex application problems This integrated networking & DCI environment is called electronic infrastructure (eInfrastructure) allowing new methods of global collaborative research - often referred to as electronic science (eScience) GRNET was one of the first NRENs in Europe to expand its services to grid and computing in general; infrastructure-oriented and application-neutral Network Infrastructure e-Science Collaborations Distributed Computing Infrastructure

4 GRNET main networking tasks Interconnects universities, research centers, academic organizations (>150), primary and secondary schools (15000) end-users Continuously upgrades the national backbone (Dark fiber backbone (Nx10 Gbps), institutions access (1 || 10 Gbps per institution) and international backbone (currently at 4*10 Gbps) Operates the GR Internet Exchange (GR-IX), peering of Greek commercial Internet Service Providers at 10Gbps each Cooperates with Greek and international research and academic institutions for the development of innovative networking services

5 GRNET network evolution: from GRNET2 to GRNET3 GRNET2: 2,5Gbps leased lambdas, 20M, GRNET3: dark fibre based, 10Gbps capable, 30M,

6 6 >50 PoPs 9000km fibers (IRU) MANs Attiki & Thessaloniki DF loops 33 cities Single-mode fiber pair 15-years IRUs Availability > 99% 1GbE interconnection over DF to the closest IP router 10GbE links for the Power Users GRNET network evolution: GRNET3

7 GRNET network evolution: from GRNET3 to GRNET4 GRNET3: dark fibres, 10Gbps capable, 30M, GRNET4: Equipment upgrades, 8M, Service Oriented Design Optical Services Layer: physical layer connectivity Carrier Services Layer: Carrier Ethernet (MPLS) interconnection IP Services Layer: IP interconnection among GRNET customers and the rest of Internet 40/100Gbps wavelengths based on PM-QPSK modulation

8 HELLASGRID (HG) infrastructure HG-01 cluster (pilot - Athens 64 CPU, 10TB FC SAN, 12TB Tape Library, gLite middleware HG02-HG07 clusters (HG project): Athens (NDC/EKT,Min EDU, IASA), Thessaloniki (AUTH), Crete (ICS-FORTH).Patras (CTI) ~1200 Cores ~40 TBytes total raw SAN storage capacity ~80TBytes Tape Library 6 extra Sites offered by Greek Universities/Research institutes (FORTH-ICS, AUTH,IASA, UoA, UoI, UOI-HEPLAB, Upatras) ~600 Cores and 200 TB of Storage Total funding ~2Me 8

9 HELLASGRID applications HECTOR: Enabling Microarray Experiments over the Hellenic Grid Infrastructure GRISSOM Platform: Grids for In Silico Systems Biology and Medicine Evaluating the impact of climate change on European air quality Density Functional Theory Calculations on Atmospheric Degradation Reactions of Fluorinated Propenes Investigating the nature of explosive percolation transition First-principles studies on traditional and emerging materials 9

10 High Performance Computing Goal is the development of a national HPC infrastructure that will join PRACE Tier-1 European infrastructure Budget 3.5MEuro Procurement and installation of HPC infrastructure Operation and provision of support services Aiming for at least a ~150 Tflops system Hosted in GRNETs existing Datacenter Support for a wide range of scientific disciplines: Biomedicince, Bioinformatics, Computational Engineering, Physics, Meteorology, Climatology, Seismology, Computational Chemistry etc. Based on the results of the HellasHPC feasibility study National survey among 29 academic and research institutes (2010) Collected requirements from 200 scientific applications developed by 162 research teams from various scientific domains

11 Cloud for R&E: the process Vision: flexible, production-quality cloud services for Greek R&E community Rationale: –Step beyond Grid in terms of flexibility and availability –Economies of scale for the community; solving understaffing problems, poor service, low maintenance –Minimizes the investment in equipment and support contracts –Know-how from NOC Service boxes (Vima service); as well as Grid Policy background: existing MoU in place for Grid computing, expanding for HPC as well Strategy: –Technical workshops and requirements capture meetings –Gradual offering of services, starting with storage, moving to VM on demand, IaaS, and then SaaS –Paving the way to public sector Funding: in the context of GRNET4 project, 2.2ME DCs; 4.5ME s/w and services)

12 Cloud for R&E: Why? STUDENT- It gives me the opportunity to test different kinds of software on a machine that I no longer need after my work is done PROFESSOR - It makes it possible for me to deploy PC labs without having to worry about specific hardware or physical space. It makes me capable of providing machines to my students for a scheduled amount of time. It gives me storage space to upload content and to share data with my students or access them through my virtual hardware RESEARCHER- It enables me to run experiments in many different environments and network topologies which I can provision easily, quickly and dynamically. I can have persistent or volatile machines according to my needs. I can also upload (besides my files) my own Images and launch Virtual Machines from them

13 okeanos service ~okeanos is set to deliver Infrastructure –Compute (Virtual Machines) –Network (Virtual Networks, private Ethernets (L2) or public IPv4/6) –and Storage (Virtual Disks) as a Service Alpha2: from March VMs – 1k alpha users Beta December 2012 Target group: GRNETs customers – direct: IT depts of connected institutions – indirect: university students, researchers in academia Users manage resources over – a simple, elegant UI, or – a REST API, for full programmatic control

14 Compute Network Storage Security Virtual Machines Virtual Ethernets Virtual Disks Virtual Firewalls okeanos service

15 1x 2x5x 8x okeanos service

16 Compute: Cyclades Files: Pithos+ Images: Plankton Identity: Astakos Volumes: Archipelago Accounting/Billing: Aquarium

17 Commercial IaaS vs own IaaS Commercial IaaS – Amazon EC2 not an end-user service – Need to develop custom UI, AAI layers – Vendor lock-in – Unsuitable for IT depts persistent, long-term servers, custom networking requirements Gain know-how, build on own IaaS reuse for own services okeanos: Design

18 okeanos: Software Stack Multiple users, multiple resources Multiple VMs on cluster Single VM Synnefo Ganeti KVM REST API

19 Web ClientCLI ClientWeb Client 2 GRNET datacenter Debian Virtual Hardware OpenStack Compute API v1.1 Direct Out of Band Access Synnefo cloud management software Google Ganeti KVM GRNET Proprietary okeanos: Platform design

20 cloud storage - Pithos Online storage for all Greek academic and research community 50 or 100 GB/user; files, groups Access by web browsers, native test apps, iPhone, Android Open source implementation and API (REST) v2 of the API, compatible with OpenStack object storage Also used in ~oceanos: – Stores custom and user-created images – Plankton provides image registry over pithos

21 ~oceanos: stats 1000 alpha users 2000VMs (windows, ubuntu, debian in order of usage) Storage: 20% disk usage. Average 20G/VM; 1 minute approx startup time for VM Scalable to thousands (Pithos to 10k) Per-VM or per-GB billing to be implemented
