FTDSS：高容错分布式共享存储机制

Computerized data has become critical to the survival of an enterprise. Company must have a strategy for recovering their data should data lose. RAID is a popular mechanism to offer good fault-tolerance. But RAID can notwork well when one more disks fail. In this paper, we present an efficient Network-based high High-Tolerance Dis-tributed Shared Storage mechanism called FTDSS. FTDSS makes use of disk space of node in Network to build alarge pubhc shared storage space. Users can read/write their file from/to the public storage space from node of net-work. Physically File is stored in each node in form of data fragment or XOR verify fragment. Because of redundant XOR fragments, file is available even when two more nodes fail. FTDSS realize distant redundant srorage. At last,this paper use experiment to prove that FTDSS can offer high. fault-tolerance and advanced performance.

FTDSS:High Fault-Tolerance Distributed Shared Storage Mechanism

Computerized data has become critical to the survival of an enterprise. Company must have a strategy for recovering their data should data lose.

In this paper, we present an efficient Network-based high High-Tolerance Distributed Shared Storage mechanism called FTDSS. FTDSS makes use of disk space of node in Network to build a large public shared storage space. Users can read/write their file from/to the public storage space from node of network. Physically File is stored in each node in form of data fragment or XOR verify fragment. Because of redundant XOR fragments, file is available even when two more nodes fail. FTDSS realize distant redundant srorage. At last, this paper use experiment to prove that FTDSS can offer high fault-tolerance and advanced performance.
