Tranche is file storage and dissemination software. Designed and built with scientists and researchers in mind, Tranche can handle very large data sets, is secure and scalable, and all data sets are citable in scientific journals. Features include a fully decentralized architecture, support for very large files, very long-term file persistence/preservation, file immutability/integrity, provenance, encryption, licensing, versioning, and citability.
Plasma implements the map/reduce framework on a compute cluster. It has its own distributed filesystem, PlasmaFS, which is transactional (ACID), reliable, and fast, and which provides a complete set of file operations. PlasmaFS can be accessed via an RPC protocol or via NFS (i.e., it is mountable). Additionally, there is a key/value database on top of PlasmaFS.
