• Common DAQ, HLT, Offline project • Online-offline computing after LS2 • Part of the Upgrade LoI of September 2012 and endorsed by

the LHCC • Present laboratories:

DAQo Labs after the transfer from 4-R and 53-R decided in April 2010 (and

delivered in December 2011)o 4-S-027: DAQ lab 45 m2

o 4-S-034: DDL lab 34 m2

HLT: none at CERN Offline:

o 13-R-018: staging room shared with PH-ESEo 13-R-020: 4 racks of servers: Grid central services, AliRoot build and test

systems; operation 24/7

ALICE O2 project

P. Vande Vyvre 3 DAQ PoW 2013-14

• Present DAQ lab (4-S-027) Dimensioned for 8 racks

Presently with 10 racks (2 from HLT during the work at P2)• Future O2 lab

ALICE upgrade started after DAQ lab decision O2 system currently estimated to ~200 racks R&D and prototyping: ~10% → 20 racks => Power: triphase 400 V, 3x160 A. Cooling: 100 kW mininmum. If possible close to bld. 3, 4, 53, 58 3 rooms of 4-R (054, 056, 060) not very much used at preset regrouped

together would be adequate

Laboratory space

P. Vande Vyvre 4 DAQ PoW 2013-14

• 4-R-054 (PH-ESE): used (2 month/year) by Markus Joos for the TDAQ school (standard infrastructure:needs only power and network, almost every room suits these needs)

• 4-R-056 (PH-ESE): kept in case a rack activity is restarted in ESE (high ceiling, mixed water available)-wasn’t it the purpose to group all ESE activitiesin Bldg 13?

• 4-R-060(Power and water pipes) . What used for?

• 2016: O2 lab in 4-R-054, 056, 060

Work to start Apr 2014 • 2019:

13-R-020: ALICE to PH-ESE after Run 2 Offline server infrastructure to be migrated to

present DAQ lab (4-S-027)
