  • Universities and Green: example University of Groningen SURFnet Best Practices ~5 MWh usage annually PUE from 1.483 to 1.18 Annual savings over 150.000 euro Aim to increase savings to 300k Best Practice What did helpt RUG verduurzamen ICT-scan they do? Het IT-centrum van de Rijksuniversiteit Groningen (RUG) wordt steeds groener. Bij de verbouwing en vernieuwing in 2010 is aan duurzaamheid specifiek aan- Virtualization dacht besteed, onder andere met een ICT-scan. Hans Gankema, hoofd server- infrastructuur, was verantwoordelijk voor dit deelproject. ‘Er viel nog heel wat te winnen op het vlak van duurzaamheid’. Faster replacement of servers Rekenhallen duurzamer Het Donald Smits Centrum voor Informatie Technolo- Het CIT beschikt over twee fysiek gescheiden reken- hallen om de diensten te kunnen leveren. Deze reken- Raise temperature gie (CIT) biedt IT-diensten, met name aan de RUG en daarnaast aan (onderwijs)instellingen in de regio. Het CIT levert kantoorautomatisering, maar ook reken- hallen gebruiken uiteraard veel energie. Toen ze in 2010 vernieuwd werden omdat de capaciteit niet meer aan de vraag voldeed, was verduurzaming van kracht voor wetenschappelijke projecten. Voorbeel- de ICT een deelproject. Hoe zorgen we ervoor dat de Optimize cooling den daarvan zijn LOFAR, Target en BiG Grid. Voor dit soort projecten heeft het CIT een supercomputer en diverse grote Linux High Performance Computing rekenhallen zo weinig mogelijk energie verbruiken? Gankema: ‘Om erachter te komen op welke vlakken clusters in huis. energiebesparing mogelijk was, hebben we in 2009 Optimize configuration 12

Zo zijn bij het CIT nu honderden serversOpenDCME model: evaluate datacenter apparatuur) De ICT-scan leverde het CIT een schat aan informatie minder nodig. op. Dit radardiagram biedt daarvan een samenvatting: ‘De scan liet ons zien dat er veel te winnen was. Door de voorgestelde verbeteringen door te voeren, moest het mogelijk zijn om bijna 75% op de overheadkosten voor energie 14 te besparen’, aldus Gankema.
  • SURFnet & green, cloud• Taskforce cloud - Cloud landscape, strategy (and is cloud green?) - Community cloud - Various vendors/operators• Experience with own infrastructure, services, public cloud providers Where’s the glue for our community• Some institutions expect to phase out on-campus datacenter 15
  • the Cloud spectrum Traditional IT IaaS PaaS SaaS You manage Applications Applications Applications Applications Data You manage Data Data Data Runtime Runtime Runtime Runtime Managed by vendor Middleware Middleware Middleware MiddlewareYou manage Managed by vendor O/S O/S O/S O/S Managed by vendor Virtualization Virtualization Virtualization Virtualization Servers Servers Servers Servers Storage Storage Storage Storage Networking Networking Networking Networking © Microsoft 16
  • SURFnet & green, cloud• Experiments with community IaaS, try use-cases, find enablers for community - SURFnet provided - Commercial operator• Secure - Consider legal implications: European Economic Area• Stimulate Green IT 17
  • Cloud deployment modelsCommunity Cloud:external part (optimal, made available) for specific usergroup 18
  • Community cloud drivers• Demand for cloud services• Service improvement - Ease of use - Federated authentication - No vendor lock-in• Cost reduction efficiency, procurement• Legal aspects• Integration with network• Emphasis on Green computing• For full or hybrid use, disaster recovery, … 19
  • SURFnet institutions and continuity• This scared many in 2002:• It’s still a “hot topic” (How do we ensure continuity best?) 20
  • IaaS cloud use-cases tested• Failover primary website to Iceland for Royal Library, planned downtime, automated via GSLB• Full website failover with replicated data for University of Groningen• Integration of servers in campus network, Open University• Integrate in curriculum, final report = results in a VM DNA Genome research @Inholland hogeschool• Provide VMs to 160 CS students (deprovisioning anyone?)• Use for various lab-work @SURFnet: ADFS, Sharepoint, filesender, secure texting, unhosted, mail-scanning, DNS, DNS traffic analysis, optic fiber network modeling... (yes, too much text on this slide, that’s intentional... really!) 21
  • IaaS use-cases: student DNA research• Integrate in curriculum, final report = results in a VM DNA Genome research @Inholland hogeschool 22
  • Brokered model Institution A IaaS provider X IaaS Broker / Institution B Operator IaaS provider Y Institution C 23
  • Easier, federated authentication 24
  • GreenQloud, friendly portal 25
  • Network integration• Networking to commercial IaaS cloud - Via Netherlight, NORDUnet, … - Use NREN-network capabilities (lightpaths) - Start machines behind own firewall? - Use NREN IP-space?• Reduce networking cost• Investigate latency impact
  • Influence on applications • Applications run outside network, different firewall or behind own firewall • Latency VLE?graph from Equinix 27
  • Green IT (1)• Efficiency of cloud services (containers, pay-per-use stimulus)• Power source / mix is important, not only about PUE Consider the GreenPeace report on Clouds 28
  • Green IT (2)• GreenQloud’s focus on Green (not just energy source)• Use other countries strengths 29
  • Some countries get energy from water…In NL, water costs energy… better bringbits to the energy, than energy to bits?
  • Proportion renewable 100% (70% hydro, 30% geo) (and cheap) 54% http://bit.ly/GSR2010 figures for 2010 electro, not heating 62%
  • DC risk assessment Cushman & Wakefield researchEnergy security, bandwidth, tax, political stability, education, water, ...
  • GreenQloud (report on energy)
  • European Economic AreaPersonal data must stay inside Iceland = OK Important for Dutch privacy law! so… what about US suppliers…
  • AWS Glacier: archive in the cloudArchive in the cloud, but is it green? Legally OK?
  • Example: BMW’s HPC in Iceland
  • Conclusion• Easier access lowers the barrier• Setting an example - other IaaS providers - institutions - NRENs - This is just a start...!• Emphasis on green!• Where is your DC in ... years? 37
