发明名称	CONTROL FOR ACCESS IN STORAGE SYSTEM WHICH DISTRIBUTES REFERENCE LOAD BY DATA MIRRORING
摘要	PROBLEM TO BE SOLVED: To provide a technology for distributing a load to a plurality of servers in a file server or Network Attached Storage (NAS) connected through a network to a client for storing data to be used by a client. SOLUTION: In receiving an access request from a client, whether or not the client issues an update request is decided. When it is decided that the client issues the update request, a master as the mirror source is selected. When it is decided that the client does not issue any update request, the mirror is selected. Then, the selected master or mirror is accessed as requested. COPYRIGHT: (C)2007,JPO&INPIT
