Grid Environment, Data Storage Method

"Grid" computing has emerged as an important new field. The Storage Resource Management, a data grid infrastructure, are designed to dynamically optimize the use of storage resources to help unclog this bottleneck. Good resolution to data storage in grid is the basis of sharing the global data. However, ensuring efficient and fast access to such huge and widely distributed data is hindered by the high latencies of the Internet. Data transmission and replication are the main operating for data management system.To address these problems need to studying a set of replication management services and protocols that offer high data availability, low bandwidth consumption, increased fault tolerance, and improved scalability of the overall system.From the market economy point of view, the essay aims at the study of data storage and replicate management in grid in order to conform to the business development in the future. Applying the price model in economy to grid, the essay advances the mechanism of the acquisition in storage resources based on supply-and-demand balance, which tries to keep the balance between supply and demand through the interaction between demand and price. In contrast to the main concern of the service suppliers interests before, this strategy safeguards the interests of service suppliers and demanders so as to complete the distribution of storage resources and task transfer, on the other hand, having studied the buffer and duplication in grid, this essay raises the design on intelligent cache management for data...
