Content • Objectives • DB Design Methodology – Readout network dataflow – Use cases – Entity relationship models – Table design • Conf.DB & PVSS (JCOP) • C routine example : use case 3 & 4 • Test Tool • Conclusion & future works
Objectives • Storage of all controllable devices from all sub- systems (electronics...) – static data (geographical position, links,...) – dynamic data (recipes, code to download...) • Each device will be stored in the Conf.DB and linked to its connectivity counterpart. • Implement tools: to populate, to configure, to maintain, to communicate with other existing tool such as PVSS.
DB Design Methodology 1. Dataflow of the system 2. Define the use cases (scenarios) 3. Build Entity relationship models 4. Design tables
ReadOutNetwork Data Flow FE cards ( L1FE) Multiplexing layer: 2 types of switch • 4 outputs(DAQ)+1(Throttle) • 2 types of traffic TRM (1 module) HLT (16 I /2 O) •HLT(1link) Level 1(16I/2O) ( HLTMS ) •Level 1 (up to 3) ( L1MS ) Ex:HLTMS_10 •Ex: VELO_L1FE00_00_00 Ex:L1MS_05 . HLT traffic Sorter Readout Network Switch RNS_Slot_00 RNS_Slot_15 Level 1 traffic ( RNS_Slot ) mixed traffic HLT possible link Level 1 possible link TFC system (readout supervisor) SFC SFC SFC SFC Storage System Switch Switch Switch Switch SFC_Switch CPU CPU CPU CPU SFC_Node CPU CPU CPU CPU CPU CPU CPU CPU CPU Farm
Use cases 1. Define the properties of a switch A switch has a type (L1MS for example) and a name (L1MS_05) and a hostname. Each switch type is characterized by a number of input and output ports. 2. Define the properties of a port 3. Find the adjacent switches (links) up or down connected to a given switch 4. Find all the connection paths between 2 devices 5. Check that a path exists between 2 extreme nodes (ie L1FE and SFC_node) 6. Retrieve all the links belonging to a given band link number and vice versa.
Path concept Example: I want to know all the possible connexion paths from VELO_L1FE00_00_00 to RNS_Slot which carries HLT Traffic. path 1: [(VELO_L1FE00_00_00, 2), (HLTMS_10, 4), HLT ] [(HLTMS_10,0),(RNS_Slot_03, 2), HLT ] → Selected path 2 : [(VELO_L1FE00_00_00, 3), (HLTMS_10, 8), HLT ] [(HLTMS_10,0),(RNS_Slot_03, 2), HLT ] → Selected path 3: [(VELO_L1FE00_00_00, 1), (L1MS_05, 5), L1 ] [L1MS_05,0),(RNS_Slot_11, 5), L1 ] → Not Selected path 4: [(VELO_L1FE00_00_00, 0), (L1MS_05, 1), L1 ] [L1MS_05,1),(RNS_Slot_11, 5), L1 ] → Not Selected first link second link RNS_Slot_11 VELO_L1FE00_00_00 0 0 1 0 5 L1MS_05 RNS_Slot Switch from 1 5 2 4 0 HLTMS_10 RNS_Slot_03 3 2 8 L1 traffic HLT Traffic
