A distributed file system integrates the storage devices on the network and stores files on remote file servers so that clients can access them through Internet anytime and anywhere. However, to ensure the reliability and security of critical data, the maintenance cost is usually high. Some researches propose solutions to use webspace as storage. These are efficient for individual users or small enterprises. However, these solutions have three drawbacks: 1) they support only single specific webspace, 2) they can not ensure data confidentiality, and 3) they can not ensure data reliability.This paper introduces a distributed file system, the General File System (GFS), which integrates the advantage of distributed file system and the convenience of webspace. GFS also integrates several heterogeneous spaces and promises the reliability and security. Besides, for users, it is easy to operate GFS through the interface provided by the virtual file system. At the end, the experiments result shows that GFS outperform than other solutions using webspace.

“…In Expand, fault tolerance is provided at file level [14,15], because not all files have the same requirements of fault tolerance degree and performance. In fact, the number of critical files for a user during a period of time is a small part of all files that belong to him, and this subset of files changes along the time.…”

Parallelism in file systems is obtained by using several independent server nodes supporting one or more secondary storage devices. This approach increases the performance and scalability of the system, but a fault in one single node can stop the whole system. To avoid this problem, data must be stored using some kind of redundant technique, so any data stored in a faulty element can be recovered. Fault tolerance can be provided in I/O systems by using replication or RAID based schemes. However, most of the current systems apply the same technique for all files in the system. This paper describes the fault tolerance support provided by Expand, a parallel file system based on standard servers. This support can be applied to other parallel file systems with many benefices: fault tolerance at file level, flexible definition of fault tolerance scheme to be used, possibility to change the fault tolerant support used for a file, etc.

However, most of the current systems apply the same technique for all files in the system. 1 This paper describes the fault tolerance support provided by Expand, a parallel file system based on standard servers. Expand allows to define different fault-tolerant mechanisms at file level. The evaluation compare the performance of Expand with different configurations with PVFS using the FLASH-I/O benchmark.
