Abstract

Storage is undoubtedly one of the main resources in data grids, and planning the capacity of storage nodes is an important step in any data-grid design. This paper focuses on storage-capacity planning for data grids. We have developed a tool to calculate, for a specific scenario, the minimum capacity required for each storage node in a grid, and we have used this tool to show that different strategies used for data replication may lead to different storage requirements, affecting the storage-capacity planning.
