Abstract: With the rapid development of networking, cloud computing and big data technology, more and more applications are changing to data-intensive, meanwhile, the number of small-ifles is growing exponentially, traditional ifle system has been unable to meet the demand for storage of massive small-ifles , storage technology of small-ifles obtains more and more attention in storage ifeld. This paper introduces the problems of massive small-ifle storage and the reasons, then introduces some optimization technology of small-ifle storage, and introduces three typical small-ifle storage systems, makes a summary and outlook for the issue of small-ifle storage ifnally.
