FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, LCG Information System Levels Resource level: Grid Resource Information Server (GRIS) –One GRIS on top of each CE, SE, RB, MyProxy (no WNs). –Sensors and scripts get status of concrete resources statically (e.g. GlueCEUniqueID) or dynamically (e.g. GlueCEStateWaitingJobs) Site level: Grid Index Information Server (GIIS) –Compiles all the information of the different GRISs in a site. –LCG-2 recommends using a BDII instead of a GIIS  Improves robustness and stability.  Called the site BDII. Top level: Berkeley DB Information Index (BDII) –Keeps all Grid information about the VOs (generally only one). –Stores information from local BDIIs or GIISs in its database. –Only queries sites that are included in a configuration file.

FP6−2004−Infrastructures−6-SSA E-infrastructure shared between Europe and Latin America 6 th EELA Tutorial, Madrid, Each site can run a BDII. It collects the information coming from the BDIIs/GIISs At each site, a site GIIS collects the information given by the GRISs Local GRISs run on CE, SE, RB, MyProxy at each site and report dynamic and static information Abbreviations: BDII: Berkeley DataBase Information Index GIIS: Grid Index Information Server GRIS: Grid Resource Information Server From LCG2.3.0 site GIIS has been replaced by “site” BDII LCG Information System Hierarchy
