Attending: John H, Steve, Jens (chair+mins), John B, Ewan, Elena, Govind, MattD Apologies: Sam, Raul 0. Operational blog posts - we had seven last quarter! Green! Ish! Nearly! 1. Summary of last week's JANET^H^H^H^H^H JISC networkshop (storage and data management related stuff only) Jens gave a summary of the JANET/JISC Networkshop - the 43rd! - at Exeter last week. Most of the summary will appear as a blog post after the election. We also discussed the JISC data centre - Ewan says they are colocating in a commercial data centre in Slough - attractive for the London institutes because space for data in London is at a premium. Also security is pretty good, as with all proper commercial data centres. 2. Post DPM workshop summary? Any new training required? Any obvious things we could/should contribute to? Are we still doing (enough) testing? We're hoping Sam went but Sam had sent apols for today, so we need to do this some other time. No one else in the call today had attended the DPM workshop. 3. Post HEPiX summary (storage and data management related stuff only) Ewan gave a summary of the HEPiX meeting. * Everyone using ElasticSearch/Logstash/Kibana * Moving from torque/maui clusters to HTCondor * Interesting talks about tape libraries (for people with tape), CERN dust monitoring * USATLAS using Amazon spot price, transfer fees are waived if low enough. Processing is equivalent to BNL. * CEPH talked about a lot but not widely used for productiony stuff. EC pools have surprisingly high CPU and RAM requirements, require high end kit. * Ethernet attached hard drives - have enough processing power on the drive to run Linux, even dCache (but not CEPH) * Computing on alternative architectures [might be useful for compute located with the data?] * Presentation of BGFS (BeeGFS), yet/just another cluster file system Steve added: * Need to watch IPv6 * SCI DB 4. Did we do milestones for the coming quarter? (maybe postpone this till next week?) Also other opportunities and things we ought to do, like the HTTP stuff. We could do our reevaluation of the postwahidian contributions to DPM? Like a report or something. 5. AOB IPv6: As Jens had talked IPv6 with Lancastrian networkers, opportunity to do work with Oxford. Also recommend that people sign up to HEPiX IPv6 which is relatively low volumen and it's where it is happening. Or being talked about. Ewan Mac Mahon: (08/04/2015 10:11:00) This is the one in Slough? Ahit's run by 'Infiniti'; I'll see if I can find a link to stuff. you can get into it to poke you're own kit; it has 24x7 staff to let you in. The shiny website is here: http://infinitysdc.net/slough-2/ Vaguely coherent rambling anyway. Steve was there too. He was presenting. That was quite fun; we had people manually configuring IPv6 on their laptops when they'd not configured it on anything at all before. I think Sam's en route to CHEP. Matt Doidge: (10:32 AM) No dounds apparently - damn you Vidyo! *sound Ewan Mac Mahon: (10:32 AM) Zounds. Matt Doidge: (10:32 AM) But Lancaster in a bit behind, and the BBC keeps stealing our Network engineer
