An Analysis Of Multi-Grained Block Management To Enhance

Abstract

In this paper, we offer a multi-grained block management strategy to improve the space utilization of file systems over PCM-based storage systems. By utilizing the byte-addressability and fast read/write feature of PCM, a methodology is suggested to dynamically allocate multiple sizes of blocks to fit the size of each file, so as to resolve the space fragmentation issue with minimized space and management overheads. The space utilization of file systems is analyzed with consideration of block sizes
