Abstract
File systems form the foundation of modern computing, which have the responsibility with data retrieval management and data storage in a wide range of media, like HDDs, SSDs and hybrid architectures. File data is spatially fragmented when it is spatially fragmented dysfunctional, living in several non-contiguous blocks scattered all along the physical storage medium. On HDDs, this spatial scattering is a direct proportional one, translating to heightened latency to the need of additional mechanical seek operations. Although random access is fast, fragmentation is complicated by SSDs, garbage collection schedules and wear leveling code, eventually reducing the effectiveness of systems and lifespan of the hardware.
Fragmentation is directly a dynamic process, continually updated when files are created, changed and deleted. More importantly, the way in which fragmentation develops the specified workload of the file system is predetermined by the imposed file system. Gaining an exact interpretation of these changing trends is beyond doubt, required to optimize future file system performance efforts. Nevertheless, notwithstanding the large amount of empirical studies on file, it is still in the field of fragmentation and is not a comprehensive one, simulation systems that could analyse the systematic timeline of fragmentation observed in an evolutionary range of workload scenarios. This simulation based study will address this particular research gap.
