Disk Performance Analyzer for Networks (DPAN) is a free tool allowing you to monitor fragmentation across a network quickly and easily. With DPAN 2.0 you can identify performance bottlenecks, scan systems from one access point, and pinpoint system problems before they become help desk headaches. Now with DPAN 2.0 you no longer have to guess how much fragmentation is affecting the systems in your network. Zero in on performance-robbing fragmentation, without having to run painstaking manual analysis on each system.
