Arun Jagatheesan (SDSC)

2. Introduction Outline Follow up actions after GGF9 GFS-BOF WG Charter
GGF10 Objectives
Administration Staff

3. Actions after GGF9 BoF [GGF9 BoF] received great interests Post GGF9
Many participants (67 persons)
Received consensus on whether should form a RG or WG
Post GGF9
Chairs had meetings w/ Data Area directors
Narrowed scope
Modified charter
Approved by GGF to form a WG

4. Charter Focus on two areas Grid File System Directory Services
Describe and manage namespace for files, access control, and metadata management
Architecture for Grid File System Services
Provides architecture of virtual file system in grid environment
Facilitates federation and sharing of virtualized data
Uses Grid File System Directory Services and standard access protocols

5. Namespace for files = Virtual file system directory = OGSA Naming + a
Virtual “path” name -> GSH (or WS-Addressing Endpoint Reference)
= OGSA Naming + a
Virtual Directory
Tree
/grid
ggf jp
data
gfs
file1
file2
translation
GSH2
(could be file data, and others)
GSH1

6. Deliverable 1 Recommendation Document:
“Virtual File System Directory Services Specification”
manage virtual file system directories in association with access permission, and other application-specific metadata
Outline by GGF 10
Draft by GGF 11
Updated draft by GGF 12
Final by GGF 13
It is possible to deliver (as subset of the above document)
“OGSA Naming Specification”
manage Global namespace

7. Deliverable 2 Recommendation Document:
"Architecture for Grid File System Services”
provide a functionality of the grid file system using the File System Directory Services and other common services
Outline by GGF 11
Draft by GGF 11
Updated draft by GGF 13
Final by GGF 14

8. Relationship with Other WGs
OGSA WG
Provide input to and follow the architecture
OGSI WG
Follow the spec and develop WS-RF-compliant file system services
DAIS WG
Collaborate through providing input on Data Services from file system perspectives, especially on access methods
OREP WG
Provide input to and leverage proposed Replication Services in GFS
GridFTP WG
Include GridFTP as a possible transport mechanism
GSM BOF
GSM will provide management of the storage system but not the virtual directory structure

9. GGF10 Objectives Outline “Survey of Grid File Systems” Document
Receive more input on the existing draft
Reach an agreement of document outline
Assign authors of the document
Get ready for GGF 11 finalization
Outline “Virtual File System Directory Services Specification”
Proposal presentation
Provide a draft to GGF 11
