Abstract： |
Through network, the method simulates local hard disk by using memory in remote machine in order to raise data processing efficiency and reliability of system data so that a distributed memory system in high performance is constructed as a short form LND. LND includes: a client end i.e. a computer in busy node; multiple servers, which are computers at more free node to provide memory for local use; the said client end and the said computers are connected through Ethernet. LND system constructs a virtual disk from memories at free nodes, and the client end maps the virtual disk to a local directory. Thus, reading/writing the directory is converted to reading/writing memory at remote side. The invention realizes communication between nodes through group communication protocol. Synchronization reading/writing performance of the invention is better than SCSI hard disk system. |
