1. ACO & AD0 DCS Status report Mario Iván Martínez

2. LS1 from DCS point of view Roughly halfway through LS1 now – DCS available through all LS1, as much as conditions (EL, Cooling) allow. Major topics for DCS during LS1 are: – M igration to WinCC OA 3.11 (from PVSSII 3.8) – Upgrade to newer OS (WS2008, SLC6) – Validate all existing and new tools in new environment – Replace obsolete hardware (new severs, new DB, phase out PCI, …) – Rationalize our installations in CR3 – Preparation for RUN2 operation (issues from Consolidation Task Force, new shifter training, …) 35th ALICE DCS Workshop26 March 2014

3. LS1 highlights up to now DCS running virtually untouched until May (when DAQ switched off) – Many post-run1 activities that required DCS operational Migration ‘tests’ started summer 2013 – Many issues discovered, thorough preparation to ease the process as much as possible for detectors, at the same time profiting to do major cleanup Major maintenance on Point 2 cooling infrastructure (phase 1) – Essentially no cooling from June to October – Significant increase in cooling power at P2, complete update of cooling control systems Replacement of obsolete UPS infrastructure – Many power interruptions from June to September

4. Migration phases Phase I (detector expert): preparing the project for the migration Phase II (ALICE DCS support): install Windows Server 2008, WinCC OA 3.11, applications (on request) Phase III (detector expert): install project, Framework, test and commissioning Important: – Use the guide and checklist available in https://espace.cern.ch/alicecontrols/DCSDocuments/default.aspx https://espace.cern.ch/alicecontrols/DCSDocuments/default.aspx – Always communicate to alice-dcs-support@cern.ch (JIRA)alice-dcs-support@cern.ch

5. DCS Operating Systems All servers already updated to ORACLE 11.2.04 Windows Server 2003 (32 bit) Windows Server 2008 (64 bit) SLC 5 SLC 6 Etm PVSS 3.8 Siemens WINCC OA 3.11 24/03/2014 Vasco Barroso on behalf of DAQ, DCS and HLT 5

6. Migration status phase completed phase started Almost all the central systems are now running WinCC OA mixed environment no major problems Deadline for the migration: end of April

9. New Computing hardware New database service – Hardware ordered (DB servers and storage) – Installation in summer 2014 – Will completely replace the existing DB infrastructure in CR3 DCS Worker nodes – Purchasing procedure launched – Installation summer 2014 – 50 DELL PowerEdge R320 will replace HP Proliant servers

10. New UPS power Before: – 60+80 kVA UPS power for CRs (>90% loaded, regularly causing problems) CR1, CR2: only core of DAQ and HLT on UPS CR3: all DCS on UPS CR4: only critical systems (e.g. BCM, TPC drift HV) on UPS After: – 200+500 kVA UPS power for CRs CR1: all DAQ on UPS CR2: production part of HLT on UPS CR3: all DCS on UPS CR4: all racks (notably all detector HV power supplies) on UPS 35th ALICE DCS Workshop26 March 2014
