Agenda

  • Check the revised storage schema entities and relationships
    • Service - Share relationship
      • Discuss : publish a Service (resource) containing all the Share(s) it manages ?
      • What is the search use case ?
    • Endpoint - Share relationship
      • Discuss : publish endpoints with the Shares they make accessible
  • Discuss main issues arised last time:
    • do we need to support Classic SE?
    • how is the information about a local available transfer protocol published?
  • Missing
    • CESEBind relation
      • Comment from ML: what about if rfio can be used from a UI? the CESEBind won't work - is this an major issue?
      • Suggestion: New Entity which keeps the ComputingShare and StorageShare Relation.

  • Attached : Storage schema UML diagram

Minutes

Check the revised storage schema entities and relationships

Sergio: can we say that a StShare is associated to at most one StorageEndpoint as manager? Answer: no, e.g. SRMv1 and SRMv2 managing same share

Summary:

Jens: we have lightpath between two sites; we may want to discover which endpoint has access to the fast link

Paul: Share: logical separation of storage space; two identified flavours:

  • as partitioning
  • as reservation
what do we model with share?

Maarten: we do not want to publish dymanically reserved space; we should publish only as partition/quotas

Main Entities::Share: A utilization target for a set of resources offered via related endpoints defined by policies and characterized by status information StorageShare: (? Specialize ?) A utilization target for a set of resources offered via related endpoints defined by policies and characterized by status information

StorageShare(0..*)---StorageShareEnvironment: discussion about if we should merge the attributes of shareenvironment in storageshare; if not, the share

  • in a storage system, we can have different storage share environments
  • a storage share belongs to one and only one type of share environment
dn: StorageShare=..., StorageEnvironment=...,StorageService=:...,AdminDomain=...,o=Grid
