BeeGFS 2015.03-r1 parallel file system — the new name for the parallel file system FhGFS — features high availability for storage servers as an enterprise feature. Based on data replication across different storage servers, automatic failovers will happen in case of storage server failures and self-healing will resynchronize the server when it comes back. It includes BeeOND (BeeGFS on demand), a stand-alone package that can create complete BeeGFS instances on-the-fly with a single command. Within BeeOND, users can not only find tools to create and destruct a file system, but also tools to perform a parallel copy of data between file systems (e.g. a global cluster storage and a per-job BeeOND instance). The system supports extended attributes, as well as access control lists (ACLs). In addition to the optional GUI-based setup of BeeGFS, setup tools allow command-line based setup of services without the need to edit configuration files. To optimize performance of multi-target storage servers under high load, storage server worker threads are grouped and dedicated to individual storage targets, resulting in better balance and fairness of parallel client request handling.
