3. TC 17-Nov-05 3 Vito Baggiolini AB/CO Background The SPS Faraday Cage will use new (PS-style) timing –New LTIM timing modules (FESA) –250 LTIM instances SPS controls are being migrated to LSA –mostly controlled by LSA already in 2006 Broader context: –New Console Manager does not yet have archives + references –Archiving of timings for SPS Faraday solves a similar need

4. TC 17-Nov-05 4 Vito Baggiolini AB/CO What are Archives/References Archive = Snapshot –Snapshot of a part or entire machine –Used to save and restore good settings –Many snapshots can be saved Reference = presently requested settings –Used to see whether an active setting is “at reference” –Monitored values are compared with references –Only one set of references exist Archives and References are related concepts –Maybe References are just a special Archive(?), at least at the DB level

7. TC 17-Nov-05 7 Vito Baggiolini AB/CO Requirements of Timing Crew “Same functionality as archives and references provided by X/Motif PS console manager” Requirements for operational usage –WorkingSets/Knobs to supervise and adjust timing parameters –Archives to save a snapshot of all timing devices for later restore –Possibility to compare values in equipment with archive values –PPM copy  copy archive from one user to another –Reliable persistence in FESA Requirements for initial configuration of timing devices –JC Bau gets list of timing settings as Excel sheet –He needs to download them into devices and save them as archive Currently, J.-C. Bau uses the Passerelle to download initial configuration to equipments, then copy to archive.

9. TC 17-Nov-05 9 Vito Baggiolini AB/CO Requirements from SPS people SPS-OP –Jorg W. and Mike L. would like to put all settings into LSA sooner or later –Paul C. advocates a solution for SPS that helps bringing SPS under LSA control –SPS people are willing to accept WorkingSets/Knobs… … but they don’t find them user friendly to change many timings –SPS responsibles want to forbid write access to equipment via Passerelle (in particular everything to do with Interlocks!) SPS-RF –Andy B. says that WorkingSets/Knobs are acceptable –With current RF timing application archives can be edited off-line

10. TC 17-Nov-05 10 Vito Baggiolini AB/CO Broader context: Archiving/References for non-LSA machines New Console Manager (responsible: Veronique) –Needs a solution for references/archives –X/Motif console manager stores these values in Directory Service –There must be a backward compatibility between X/Motif console manager and new console manager OP should not be forced to upgrade to new CMGR Same archives/references required from X/Motif and new CMGR CO/DM point of view –The Directory Service should not contain operational settings such as archives/references –DM is willing to provide scripts to convert data from old to new (and back if necessary) –Ronny and Chris actively participate in LSA DB design

17. TC 17-Nov-05 17 Vito Baggiolini AB/CO Analysis with Regard to Requirements PS-Style GUIs –Good for timing and PS-OP –Acceptable for SPS-OP and SPS-RF LSA-style storage  easier future integration with LSA –Good for SPS-OP (easier migration towards full LSA control) –Good for CO/DM (separates configuration data from operational settings) Simple server based on LSA approach, not full LSA system –Good for CO + LSA team (more time for more urgent LSA work) –Good for CO + PS: can be generalized to all non-LSA machines (PS complex) Possibility to avoid Passerelle with Excel  DB link –Good for SPS –Should be acceptable for Timing crew

25. TC 17-Nov-05 25 Vito Baggiolini AB/CO Assessment Assessment based on LEIR experience –Non-trivial mapping between LSA settings (SuperCycles, Cycles, BeamProcesses) and timing (users) –We’ve found a solution for LEIR which needs to be generalized  Premature  More complex  Bad compromise for SPS (Won’t make anyone happy)  Cannot be used as archive/reference for new Console Manager Recommendation: –Study how new (PS-style) timing and LSA settings can be seamlessly combined for all SuperCycle/Cycle configurations –To be pursued by LSA team…

26. TC 17-Nov-05 26 Vito Baggiolini AB/CO Conclusions Recommendation for now: PS-Style GUIs with simple archive/ reference server using small part of LSA code and DB tables –Best compromise for SPS Faraday Cage in 2006 –Can be used for generalized archive/reference solution for console manager In medium term, all SPS should be in LSA –Archives and References in LSA –Requirements of timing crew have to be further analyzed –More thoughts and experience are needed A hybrid solution will make nobody in SPS happy
