12. Operations – Updates: CHiPP Services Overview12

13. dCache Upgrades No upgrades since last F2F
Next minor upgrade will be in Feb. 2018
Next major upgrade to the gold release (3.2) will be in mid 2018

14. Ticket report

15. LHCb issue
About 40% of the jobs were failing for few weeks in December
We did several debug
No more input from LHCb
The Issue solved itself (from LHCb side)

16. Meltdown/Spectre
Kernel patch applied as for EGI requiements (Only Meltdown fixed)
Performance degradation due to the patch
No FW so no solution for Spectre

17. Singularity Phoenix all setup for CMS requirements
Daint under investigation
Working on Shifter to enable CMS workflow
NOT NICE TO GET IMPORTANT REQUIREMENTS LIKE THIS

18. VO Rep one-on-one followups
Propose schedule for meeting 1-2 times per year:
We propose 2 meetings in between the F2F
VC or in person up to the VO
We are still working on enabling VO Rep to access their own logs

19. Plans

20. IPv6 Deployment CSCS is IPv6 ready Present configuration
We are using IB network
IB Gateways do not support IPv6
IPv6 Implementation plan (dCache: ~20 hosts)
Use IB cards + adapters + 10G twinax-cables on current host (CHF 40.00)
10G switches are already deployed and available
Security needs to be managed

21. Daint outages Center-wide outage (Feb 21 ) In the near future we will:
move all LHConCRAY nodes to the same electrical group for increased performance and jitter reduction.
increase DVS nodes from 5 to 8 (same electrical group).
Deploy new nodes expected in April
In the near future we will:
Add an additional TEST ARC-CE to Dom (the TDS of DAINT) so we can evaluate updates and different utilization models (opportunistic?)

22. Future Operations Install next Phase on Cray & SAN (Phase M)
Work on Scratch replacement
Centre-wide outage Feb 21st, June 13th, Oct 10th
dCache latest minor version (v3 not yet)
Upgrade perf-sonar
Try to stay out of RH7.4 + OFED4 upgrade in Phoenix
ATLAS storage accounting
IPv6 (Evaluating how to migrate)
Access to CHIPP Monitoring
Trips:
dCache workshop
HEPIX
CVMFS workshop
Follow-up with GDB on HPC 22

23. Resource Planning Compute 2018 110 kHS06 Installed 99 kHS06 pledged
40:40:20
Storage 2018
4 PB installed and pledged
