| 摘要 |
The present invention relates to a distributed file system of a cluster in a virtual cloud environment and a data replication method including a driver domain which exists in a physical node of each virtual machine of a cluster which includes at least one virtual machine, receives replication data from a node performing data replication of a distributed file system, and transmits the received replication data to the virtual machine on the basis of availability of a resource of the physical node having the virtual machine mounted thereon. According to this configuration, the distributed file system of a cluster in a virtual cloud environment and the data replication method of the present invention can constantly maintain fault tolerance of a physical level and improve performance of the distributed file system according to reduction of occurrences of replication overheads by having the driver domain receive replication data instead of the virtual machine and having the virtual machine transmit the received replication data to the virtual machine according to system resource availability of the physical node having the virtual machine mounted thereon. |
