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

- 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.
Thanks!
Any news regarding Kaiseniemi?

“We don’t know”.
There has been a meeting between EISCAT and members of the local council. The council people present heard what EISCAT had to say, but were not mandated to give an answer. They will bring the matter back to the council and let EISCAT know. There is hope the answer - good or bad - will come before the end of October.
