The Fujitsu distributed file system (DFS) provides the following features:
It can use ETERNUS, Fujitsu's external storage device that boasts high reliability and operability.
Using RAID, it is not necessary to produce data replicas with software such as HDFS, meaning much faster access.
Furthermore, you can add just the resources currently required, since it is possible to size slave servers and disks individually.
This product supports the standard Linux file access interface (POSIX).
Integration is easy and efficient, since data input and output are possible without having to change the application.
Memory caches in the slave servers can be allocated efficiently, leading to improved processing speeds.
The management data information (metadata) acquired on the various servers is maintained in caches, and this means that there is no need to constantly access the network to acquire this information.
