All, very brief notes from my presentation at the E3D stakeholder meeting. Slides attached.

/Lars

• Presentation went well; E3D people understood the suggested change from routed network to point to point, with all traffic going through a data centre. I believe this was generally accepted as a better way.
• Led to good discussion of picking a data centre, and the important of doing so early. Craig asked relevant questions on what happens if they have to move from DC A to DC B
• Craig seem not uninterested in using a data centre on-ring and close to Tromsø that is becoming available
• Craig appear to be slowing moving away from 90’s style thinking about computing and network. The NeIC project has been good in this respect.
• Craig is also considering keeping all data in Skibotn for the first couple of years. We might like to think about a grow-as-you-go plan (i.e, from 100G from site to TB from sites, and Several participants were very interested in the TB/s options and how that changes long-term computing options.
• I suggested that we stop thinking about the network as a separate thing, but rather consider it an integral component in the computing - instrument, site network, site computing, WAN, DC network, DC computing, storage. The WAN can go anywhere in that picture, really.
• None of this was conclusive. It was a conversation starter. My immediate guess is that they will go for 2x100G per site now, moving to much more capacity in the future. Possibly, this will be linked with a model where they do all computing at Skibotn now, and move to a DC in 2-3 years.
