1. Operational support for Tier1 P: Matteuzzi

2. Operational support for Tier1 Controls of: a) Infrastructural problems b) Sw problems a) Detected by the “alarm system” (http://alarm.cnaf.infn.it/webclient/accwebmgr.asp) It allows control on: Refrigerator, UTA, UPS, Electric Generator, Transformer, Temperature in T1 room, Accesses to room, Fire extinction system Alarms: minor alarms sent by Mail and SMS major alarms sent by telephone calls

3. Operational support for Tier1 b) Nagios system allows control on: switches, geographical links, Log servers, DNS, Mailing, Storage servers, Farming Alarms sent by Mail and SMS We are now organizing the service in this way: For item a): ~30 persons (from all services including Grid) on weekly shift during the year; 2 weeks/year for each person on-call 24h For minor alarms, action asap For major alarms, immediate action (in 30’)

4. Operational support for Tier1 For item b): ~ 20 persons (synergy required with Grid team) Direct control during work-time On-call out of work-time Action via Remote access with ADSL Problem solution as best effort

5. Tools for operational support for Tier1 Alarm system Monitoring system on Farm and LSF Queues Monitoring system on Storage and Castor (by Nagios) Monitoring system on Network (by Nagios)

6. Human resources for the infrastructure problems Now: 1 coordinator and 1 technician (Strongly insufficient. Big effort to mantain the actual system and study solutions to optimize the entire infrastructural system) Trend: 1 coordinator, 2 technicians + 2 temporary contracts (In future we must control more than 3.5 KW, 3 Transformers, 3 Electric Generator, 3 UPS, Refrigerator for 1.5 KW of refrigeration power)
