The Disk Performance Analyzer for Networks is a stand-alone utility that detects and reports fragmentation-related performance loss on networked systems. The Performance Analyzer provided never before available single-point analysis of systems requiring defragmentation attention to achieve optimal performance. With Disk Performance Analyzer for Networks you can zero in on the machines that need attention and handle them before they turn into a helpdesk problem.
After installing and launching the utility, you are presented with a list of computers on your domain(s) available for analysis. Once you have selected target computers, a small agent is temporarily copied to these computers to begin an analysis. The agent quickly and unobtrusively gathers disk fragmentation information from the remote computers and reports this data to the Disk Performance Analyzer for Networks main console. The agent then completely removes itself from remote client systems.
After collecting all the analysis data, Disk Performance Analyzer for Networks will create and present a comprehensive report showing the fragmentation related performance degradation on selected remote computers.
