Configuration Database Lana Abadie, LHCb week, May 25

The configuration database Storage of all controllable devices with –their properties –the links between them –their hierarchy The control system can be bootstrapped from the configuration database.

DB Design Methodology (ex: the TFC system) –TFC dataflow

THOR_00 (TFC) 16*16 TTCtx_ X transmitter(16*14) TTCocX_Y Opt. couplers(1*32) TTCrxX_Y_W receiver (1*32) SubDet_L0FEX_Y_Z (?*1) SubDet_L1FEX_Y_Z (?*5) Munin0_X 32*2 DAQ (readout net) ODIN_X Readout s. MuninL0_00 16*16 MuninL1_00 16*16 Throttle set of links TFC set of links DAQ set of links TFC set of links sometimes possible X ≤16 used 1 X≤16 Y≤14 W≤32 X≤16 TTCrxX_Y receiver (1*32) SubDet can be (VELO, RICH, L0MUON,...)

DB Design Methodology (ex: the TFC system) –TFC dataflow –TFC system : use cases

TFC system : use cases List of possible scenarios (2 examples) –Find all the connection paths between 2 devicesFind all the connection paths between 2 devices –Define the routing table of the TFC switchDefine the routing table of the TFC switch

Path concept Example: I want to know all the possible paths from VELO_L0FE00_00_00 to TFC switch (THOR) Path : [(VELO_L0FE00_00_00,0), (TTCrx00_00_00, 0), TFC] → 1 st link [(TTCrx00_00_00,0), (TTCoc00_00,0),TFC] → 2 nd link [(TTCoc00_00,0),(TTCtx_00,0),TFC] → 3 rd link [(TTCtx_00,0),(THOR_00,0)] → 4 th link VELO_L0FE00_00_00 TTCrx00_00_00 0 TTCrx00_00_11 TTCoc00_00 TTCtx_00 T HOR_00 TFC link

System_L0FE00_00_00 TTCrx00_00_00 0 TTCoc00_00 TTCtx_00 T HOR_00 System_L0FE00_00_01

TFC switch routing table Identified by a number The way it is stored in the database (cf schema below): –input nbr : 5 –output THOR switch connection busy

DB Design Methodology (ex: the TFC system) –TFC dataflow –TFC system: use cases –Entity relation model & Table design

Entity relation model Device +Device Name +Device type +Active Thor Routing RoutingId switch name Output word Input nbr 1N Table design Device +Device Name (pk) +Device type (fk) ref SwitchType(Switch_type) + active Thor Routing RoutingId (pk) switch_name(fk) references device_list(devname) Output_ptnb Inp_ptnb unique(RoutingId, output_port_nb) 1 N

Presentation of the demo (2/2) Connection to the hardware (from the TFC system) via PVSS Creation of the different devices (TFC switch, read out supervisor...) in PVSS and storage in the fw_ tables Insert in other tables the different connectivities between devices Queries to the tables (tfc_path) to get the connectivities between the TFC switch and the subsystems. Links to other existing panels to configure the different components with possibile storage in the fw_ tables under different versions Make the updates in the other tables

–Design of TFC and Read Out Network system tables completed –First prototype built to show possible queries to the Conf.DB via PVSS Future work: –Design of other subsystem tables (connectivities) –Optimization of performance –Design of a generic API

Thank you for your attention QUESTIONS ?

Extract of the fw_device_properties How the datapoint called TFC:Odin/ODIN_00 is stored in the Conf.DB ? One attribute and its value per line are stored
