Agenda

  • Quick issues
    • EndpointCapability
    • Nordugrid example : Share-localID, why "LocalID" instead of "ID"
    • Architecture: multivalued ? open numeration ?(tape, disk, multidisk, DVD, ...)
    • Use case for scenario; tape system down, disk ok: are associated shares using both should be marked as down, too?

Examples :

  • GSSD

Participants

  • Flavia Donno (CERN)
  • Maarten Litmaath (CERN)
  • Paul Miller (DESY)
  • Felix Ehm (CERN)

Minutes

  • StorageCapacity - StorageEnvironment:
    • Environments should be homogenous and should NOT overlap in order to retrieve meaninful (no double counting) space usage information. Must be mentioned in the GLUE specification.
    • Action: Felix, clearify with other Grid Infrastructures if this collides with their requirements
    • SCHEMA: removed Aggregation of Resource and Capacity
  • Architecture attribute (StorageEnvironment):
    • not clear if this is the right place
    • Maarten : strong (non-operational) use case for WLCG
    • Paul: drop architecture in favour of having anyway a type in the assigned storage capacity which reflects this information
    • Paul: natural place is the 'Capacity' - but then it must be published with every capacity entity (redundant information)
    • SCHEMA: Architecture goes into Capacity as optional single valued attribute
  • Flavia : Use Case for having a status in the AccessProtocol entity
    • most suitable attribute type: ServingState_t
  • StorageCapacity - MappingPolicy relationship:
    • suggestion in order to have the possiblity for VO accounting info
    • does this make the schema overcomplex and does it lead to misunderstanding ?
    • not necessary a all if a Share is assigned to one VO (WLCG)
    • however, use case #3 for NorduGrid
    • Understand the impact of Sergios's suggestion for final decision
  • SCHEMA: Capacity size attributes all optional
