Fastdfs is a lightweight open source Distributed File systemFastdfs mainly solves the problem of large capacity file storage and high concurrency access, and realizes load balance in file access.FASTDFS implements a software-style raid that can be stored using a cheap IDE hard diskSupport Storage Server Online expansionFiles that support the same content save only one copy, saving disk spaceFastdfs can only be accessed through the client API and does not support the POSIX access methodFastdfs is

services. and distributed storage is to use these storage services, scattered data stored on multiple servers, so that data storage implementation of simple, intelligent operation, stable, reliable, easy to expand.II: MogileFS Software Introduction1.
