IPv6 WLCG Site Survey

DRAFT

Questions:

  1. Is your site already offering connectivity, routing and naming services for IPv6 end systems (i.e. is your site already connected to the worldwide IPv6 network and ready to support IPv6 end systems)?
  2. If so, have you already enabled IPv6 on some of the services you manage? Please provide details on which services are enabled
  3. If your site is not yet IPv6-ready, are there plans for this? If so, what are the timelines?
  4. Does your site currently have problems with allocating a sufficient number of IPv4 addresses? Or foreseen in the near future?
  5. Are there other issues you are aware of? Or interesting work going on in this area?
  6. Any other comments?

Answers by Site

Site Name Date when entered IPv6 connectivity IPv6 enabled services ETA for IPv6 readiness IPv4 exhaustion issues Other issues and related work Comments
NDGF 12.5.2014 Yes, but not to all of site For limited services, not main storage yet About one year No. Storage has plenty, a lot of worker nodes use private networks 3 out of 8 subsites are fully IPv6 connected, the rest are partially or IPv4 only
praguelcg2 14.5.2014 Yes. Many services yes but not all Partially ready now, the rest depends on service providers Yes
UKI-LT2-IC-HEP 14.5.2014 Yes Most services enabled but not dCache storage element Essentially ready now. Storage element should be ready when when dCache v2.9.0 goes into production No
UKI-LT2-QMUL 14.5.2014 Yes Perfsonar, RIPE Atlas probe, test SE Waiting for confidence that middleware won't break No. Worker nodes behind NAT. Sufficient IPv4 for world facing services (and University sees no risk of running out in the immediate future).
UKI-LT2-UCL-HEP 14.5.2014 No No Waiting for central IT to announce service, and middleware to be thoroughly tested No immediate shortage Central IT network division has set up IPv6 working group. I'm not up to date with their plans.
UKI-LT2-Brunel 14.5.2014 Yes Perfsonar enabled. Experimental DPM storage enabled and passing Nagios tests. Only limitation to completely convert to dual-stack is DPM-xroot: No IPv6 version available. However, we have tested and jobs can run on dual stack nodes using IPv4 xroot. No
UKI-SOUTHGRID-CAM-HEP 14.5.2014 No No Service available from central IT, IPv6 addresses allocated. No immediate shortage Central IT enthusiastic about IPv6 deployment. Lack of manpower at site
UKI-NORTHGRID-LIV-HEP 15.5.2014 No No Planning in progress No immediate shortage
FNAL 14.5.2014 Yes, but limited web, email and services on IPv6 test network TBD No IPv4 exhaustion issues (yet) IPv6 and 100 Gb/s test networks are being combined
UKI-SCOTGRID-DURHAM 15.5.2014 No No No allocations have been finalised by Central IT None
