• A around 120 participants
• Many sites started using OpenStack
• CERN Migration from AFS (impacted various sites) Replacement options (CERN Box, BNL Box, IHEP Box, EOS, CVMFS, etc)
• Many sited reported consolidation and new facility
• Increasing adoption of CentOS /SL7
• Migration to Grafana for many sites
• Increasing adoption of IPv6 dual-stack at many sites
• Puppet migration from 3 to 4
  • mostly smooth
  • main issue Cron is now integrated in puppet (no more Cron moule is needed)
• Very nice presentation on elasticsearch at CERN
• Consolidation and unify CERN IT monitoring
• Old school logging at Blabit and IN2P3
  • syslog-ng

Systems:

• During the maintenance updated and cleaned all VM
• Some swapping issues, working to track all jobs memory and cpu usage live
• Working on a new node monitoring dashboard (CPU,Memeory,Swap,etc.. usage) with Grafana and Metricbeat

Storage:

dCache

• - update from 2.13.50 to 2.13.58 issue
• - migrated ~1.2PB and decommissioned the IBM DCS3700, deployed new ~1.6PB from NetApp E5600 systems
• - working with CMS support for spacemon deploy
• - working on pp dcache cluster (future upgrade)

GPFS

• - new GPFS servers ready, will be deployed online
• - GPFS new layout in place: Server-Cluster / WN-Cluster / Daint-Cluster

PSI

• We are currently in an emergency downtime (since 6.6.2017) due to a controller failure on our /home system server. The repair parts arrive this afternoon.
• Accounting numbers (from scheduler) from last month

UNIBE-LHEP

• New hardware, partially installed: 480 cores (E5-2630 v4 @ 2.20GHz) and 150 TB of storage

UNIBE-ID

• Deploying singularity un Ubelix. Use case for ATLAS, since the cluster will transition to Centos7 by end of year and this OS is still a bti problematic for ATLAS. They will start soon testing using the homegrown image also used by UNIBE-LHEP for running on SwitchEngines.

UNIGE

• Hardware: Upgraded 6 machines (in May 2017)
  • Old machines acquired in 2012, but upgraded in May 2017
  • Added 6x32 (192) cores and 6x96 (576) GB of RAM memory: 1 User Interface and 5 bacth nodes
  • It cooresponds to a ratio of 3 GB of RAM memory per core
• Operations: May 2017 (CPU effciency):
