摘要

In order to achieve high performance data access a typical technique used in the past was application data access pattern. In this paper we formulate a similar approach for Grids through the usage of I/O phases. Phases allow to define different DataGrids for different usages, but in order to adapt this to the huge and heterogeneous Grid infrastructure we need some way to select the storage resources. This is accomplished through the usage of grouping techniques based in locality and performance using three metrics distance, server I/O performance and network performance. Those metrics lead to the definition of three entities, I/O community, intragrid and intergrid. Those entities combined define several DataGrids that are assigned to different application I/O phases. An evaluation of those ideas is presented through GridExpand, a data access middleware for Grids.
