A Taxonomy of Distributed Storage Systems

Revision : 1.148 This paper presents a taxonomy of key topi s e e ting resear h and development of distributed storage systems. The taxonomy nds distributed storage systems to o er a wide array of fun tionality, employ ar hite tures with varying degrees of entralisation and operate a ross environments with varying trust and s alability. Furthermore, taxonomies on autonomi management, federation, onsisten y and routing provide an insight into hallenges fa ed by distributed storage systems and the resear h to over ome them. The paper ontinues by providing a survey of distributed storage systems whi h exemplify topi s overed in the taxonomy. The sele tion of surveyed systems overs a variety of storage systems, exposing the reader to an array of di erent problems and solutions employed to over ome these hallenges. For ea h surveyed system we address the underlying operational behaviour, leading into the ar hite ture and algorithms employed in the design and development of the system. Our survey overs systems from the past and present on luding with a dis ussion on the evolution of distributed storage systems and possible future work.
