File system performance

Storage Performance: Block vs. File System

File system performance is often a major component of overall HPC system performance, and is heavily dependent on the nature of the application(s) generating the load. To achieve optimal performance, the underlying file system configuration must be balanced to match the application characteristics. Hence the basis for Lustre. However, regardless of the style of file system (such as UFS, NTFS, ZFS, or any of the parallel file systems used today), the underlying disk structure dictates the performance capabilities of these file systems.
