FhGFS

FraunhoferFS (abbreviation FhGFS ), the Fraunhofer Parallel File System, is a parallel file system, specifically optimized for use in the field of high performance computing. The data throughput is in the foreground. It is developed at the Fraunhofer Institute for Technical and Industrial Mathematics ( ITWM ). FhGFS is currently being used in several supercomputing facilities, including some of the fastest supercomputers in the world ( according to the Top 500 Classification ).

Access to user data is parallelized by the data are divided into so-called chunks. The chunks are stored independently of one another distributed on multiple servers. The management of the data and the assignment of a file to the corresponding chunks incorporate special metadata server. FhGFS supports distributed across multiple servers metadata, making file access should be very scalable. The connection of each server is done using either RDMA over Infiniband or TCP / IP connections (Ethernet, IPoIB ).

The developers put a priority emphasis on scalability, flexibility (eg, support for multiple network interfaces and dynamic failover ) and a simple usability (eg by integrating your own graphics utilities).

FhGFS can be downloaded and used free of charge. The Fraunhofer ITWM offers paid support.
