Remote Virtual the Data Storage

Almost all computer users know Windows Explorer. With the windows explorer, a user could do the operation file/directory, such as seeing the structure of the hierarchy from the directory, copied some files et cetera. In other words, a window explorer had file manager facilities. This research will discuss the development of the application of the data storage based on web that had file manager facilities (remote virtual the data storage) with the previleges. This research could be applied for the management of the lectures data in the class or in the computer laboratory of a institution

Improving the Throughput of Remote Storage Access Through Pipelining

Abstract. Data intensive applications constitute a large and increasing share of Grid computing. However there are relatively few results on how to improve the efficiency of the basic data transfer mechanisms used to move large data set in and out of Grid nodes. In this paper we describe a simple and general technique to improve the throughput of data transfer protocols and we demonstrate it on the SDSC Storage Resource Broker (SRB), a remote storage access middleware for supercomputer applications. We achieve a maximum performance improvement of 43%/52 % for remote reads/writes larger than 1MB with a few changes to the original SRB protocol. The protocol was restructured by introducing a notion of pipelining that enables the overlapping of the various stages of the data processing, such as network transfer and disk access. We present a detailed analysis of the pipelined SRB implementation and of the pipeline cost model we used to drive our design. 1
