Abstract： |
Based on virtualized networked storage system of storing LAN, system kernel module maps operation address requested from I/O of file system to proper networked-disk so as to realize function of virtualized storage. Meanwhile, request of synchronous operation carried out for kernel metadata through Ethernet is submitted to other nodes in computer cluster system. Then, under integrating control of central control and management module in supervisor node machine, corresponding operations are carried out for metadata, operated result is added into metadata table in kernel module in order to make metadata of virtual storage in all nodes of cluster system keep consistent. Thus, the virtualized system provides a view of networked storage resources in consolidation form to realize distributed virtualized storage system. |
