OrangeFS is easy to install, requiring only a few dependencies, which are often pre-installed on most Linux systems. Please see the Planning section of the Installation Guide for detailed information.

Related Software


MPI-IO is the recommended interface for interacting with OrangeFS from a parallel application. MPI-IO support for OrangeFS version 2 is provided through the ROMIO package. The latest versions of ROMIO as distributed with MPICH2 already contain OrangeFS version 2 support by default.

Please visit the MPICH2 web site to download this software or find out more information.

pNFS with OrangeFS

Collaborators at CITI have designed and implemented a prototype of pNFS that exports an OrangeFS filesystem providing high-performance over an NFS v4 protocol. See the CITI pNFS website for further information.

OrangeFS FUSE Interface

John Chandy at the University of Connecticut has written a FUSE interface for PVFS v.2. This allows OrangeFS clients to access OrangeFS volumes from non-Linux machines, such as Mac OS X and FreeBSD. More information is available from the pvfs2fuse website.
NOTE: FUSE support for OrangeFS is included in the release.


OrangeFS releases have been tested for stability. We provide fixes to bugs found in the most recent release as patch sets. Each patch set can be applied to the most recent release until that release is superseded.
