Charter

Focus/Purpose

Data in a grid can be of any format and stored in any type of storage systems. There can be many hundreds of petabytes of data in grids, among which a very large percentage is stored in files. A standard mechanism to describe and organize file-based data is essential for facilitating access to this large amount of data. The Grid File System Working Group (GFS-WG) will provide specifications of Grid File System Directory Services and Architecture of Grid File System Services.

The specification of Grid File System Directory Services will describe and manage the namespace of federated and virtualized data from file system resources, access control mechanisms, and meta-data management.

The specification of Architecture of Grid File System Services will specify the hierarchical structure to facilitate federation and sharing of virtualized data from file systems in the grid environment by providing the virtual namespace that will allow association of access control mechanisms and meta-data of the underlying physical data sources.

Scope

The GFS-WG will first focus on the specification of the Grid File System Directory Services. The specification will provide features such as (a) virtualized hierarchical namespaces for files or potentially other type of data (such as live data feeds), (b) efficient and transparent file sharing, and (c) flexible management of inter-organizational data access controls, and (d) ability to describe and manage file-system and application-specific metadata.

Then the GFS WG will provide a specification of Architecture of Grid File System Service. The specification will focus on the organization and infrastructure of file systems in the grid environment. The architecture will make the implementation of upper or lower level Grid services defined by other GGF WGs to be easily applied to file system data sources.

In order to produce the specifications, the GFS-WG will create a quick survey of the state-of-art technologies to facilitate the discussion for the standardization.

Goals

  1. Recommendation Document: "File System Directory Services Specification"
    This document will describe a specification of a grid service to 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
  2. Recommendation Document: "Architecture for Grid File System Services"
    This document will describe a recommended architecture for a grid service to provide a functionality of the grid file system. This service will provide POSIX like I/O operations using the File System Directory Services and other common services.
    • Outline by GGF 11
    • Draft by GGF 12
    • Updated draft by GGF 13
    • Final by GGF 14
Two pre-study based information documents will be produced before the Recommendation Documents:
  • A Survey of the Major Grid File Systems
  • Requirements and use cases for Grid File Systems

BoF at GGF9

6pm to 7:30pm on Tuesday, October 7 (Mayfair room)
