- MogileFS
MogileFS was created by
Danga Interactive for useClarifyme|date=March 2008 withLiveJournal . It is similar to the "Andrew File System " in its design goal. It is different from a traditional filesystem in that the user has to access files via an API. However, it is possible to implement the file system in user space using FUSE or a similar package.MogileFS enables horizontal scaling of storage across any number of machines. Files are replicated between machines according to customizable rules such that at any time a number of drives or machines could be lost without data becoming unavailable. It is designed for high volume applications, such as high traffic websites, to spread storage across cheaper machines without relying on technologies such as NFS.
A typical MogileFS cloud consists of a database, some number of trackers, and some number of storage units.
The name is an
anagram of " [http://en.wiktionary.org/wiki/OMG OMG] files".Notable Users

They chose this overHadoop as it was felt to be able to handle billions of small files better than HDFS, that only scales if files can be broken into blocks of 64MB or larger.
