MogileFS is our open source distributed filesystem. Its properties and features include:
Application level -- no special kernel modules required.
No single point of failure -- all three components of a MogileFS setup (storage nodes, trackers, and the tracker's database(s)) can be run on multiple machines, so there's no single point of failure. (you can run trackers on the same machines as storage nodes, too, so you don't need 4 machines...) A minimum of 2 machines is recommended.Automatic file replication -- files, based on their "class", are automatically replicated between enough different storage nodes as to satisfy the minimum replica count as requested by their class. For instance, for a photo hosting site you can make original JPEGs have a minimum replica count of 3, but thumbnails and scaled versions only have a replica count of 1 or 2. If you lose the only copy of a thumbnail, the application can just rebuild it.

For the past six years Microsoft has sponsored the 15,000 member SUA Community forum hosted by Interop Systems. Interop has ported hundreds of additional open source tools to the SUA (and SFU / Interix) environment -- such that users now have a complete Unix/Linux environment available to them at no cost. In addition, Interop Systems was responsible (under contract from Microsoft) for updating the GNU and BSD utilities that are provided by Microsoft. Updates to the Microsoft set of utilities are maintained and posted in the SUA Community alongside Interop's set of open source tools.
