Abstract： |
Characters of the invention related to network memory technology area are that based on own developed FC-SAN system, synchronous remote mirrored image is realized in ScrverFree mode completely by using method of two stage double storage node cluster in two stage of memory; mirrored procedure is shielded from host system, does not use any resources of host cluster, and only tiddly write delay of mirrored image is introduced; the mechanism provides data service sequentially when a node is disabled, and provides resynchronization of background data after system reconstruction so as to meet guarantee of data security. The invention possesses extensibility and high compatibility, being suitable popularized networked mass storage system. The invented system is applied to networked mass storage system developed by Tsinghua Univ. own and passed test. |
