IP File system Arla is a free AFS client implementation. Other planned and implemented things are all the normal management tools and a server. Coda is a distributed file system. Among its features are disconnected operation, good security model, server replication and persistent client side caching. The Rio project is investigating how to implement and use reliable memory.
Reliable memory enables dramatic improvements in reliability and performance.
A Solution to the Metadata Update Problem in File Systems TCFS is a Transparent Cryptographic File System that is a suitable solution to the problem of privacy for distributed file system. By a deeper integration between the encryption service and the file system, it results in a complete trasparency of use to the user applications. Files are stored in encrypted form and are decrypted before they are read. Tertiary Disk is a storage system architecture to create large disk storage systems that avoid the disadvantages of custom built disk arrays. We use commodity, off the shelf components to develop a scalable, low cost, terabyte capacity disk system.
