摘要： Database synchronization processing is completed within a reasonable time, using narrow-band network that connects a primary site to a secondary site, to reduce the running cost of a system. A primary DBMS has a transaction executing unit for reading a primary DB of a primary storage system to update data as requested in an update request, and a write unit for writing the updated data in the primary storage system. The primary storage system includes an unnecessary information removing unit for overwriting an unused area in the written data successively with one of a preset character and a preset value. The primary storage system is connected, via a network, to a second storage system which stores a copy of the primary DB. The primary storage system is connected to the network via a network device which has a data compression unit for compressing a succession of the same value.

摘要： The invention relates to a method of virtualizing a plurality of network storages into a single-view file system for a client and obtains information about an object's storage location without inquiring of a resource manager. The method determines a network storage that should store an object based on a hash value generated from a logical identifier for the object to be accessed. While accessing the object, the method computes the hash value for the object's logical identifier to determine a network storage that should process an access request. Consequently, the method eliminates the need to inquire the object's storage location when the access request is issued. Further, the method eliminates the need to maintain the object's storage location when the number of servers is increased or decreased, thus providing easy management.
摘要翻译：本发明涉及将多个网络存储器虚拟化为用于客户机的单视图文件系统的方法，并且在不查询资源管理器的情况下获取关于对象的存储位置的信息。该方法基于从要访问的对象的逻辑标识符生成的散列值来确定应存储对象的网络存储。在访问对象时，该方法计算对象的逻辑标识符的哈希值，以确定应处理访问请求的网络存储。因此，当发出访问请求时，该方法消除了查询对象的存储位置的需要。此外，当服务器的数量增加或减少时，该方法消除了维护对象的存储位置的需要，从而提供容易的管理。

摘要： Since no control of accesses made by a computer as accesses to a storage apparatus is executed, the computer can be used illegally to steal and improperly change data stored in the storage apparatus. Thus, an access-control mechanism external to the computer is constructed to solve this problem. That is to say, the control of accesses is executed in the storage apparatus and a network apparatus for each program executed by the computer. In order to enhance the implementability of such control of accesses, the control is executed without extending a variety of protocols of communications among the computer, the network apparatus and the storage apparatus. By implementing the control of accesses in this way, a program other than programs specified in advance is not capable of making an access to data stored in the storage apparatus. Thus, even if the computer is used illegally, data stored in the storage apparatus can be prevented from being stolen and changed improperly.
摘要翻译：由于不执行对计算机进行对存储装置的访问的访问控制，因此可以非法地使用计算机来窃取和不正确地改变存储在存储装置中的数据。因此，构造了计算机外部的访问控制机构来解决这个问题。也就是说，在由计算机执行的每个程序的存储装置和网络装置中执行访问的控制。为了提高这种访问控制的可实现性，在不扩展计算机，网络装置和存储装置之间的各种通信协议的情况下执行控制。通过以这种方式实现访问控制，预先指定的程序之外的程序不能访问存储在存储装置中的数据。因此，即使计算机被非法使用，也可以防止存储在存储装置中的数据被盗窃和不正确地改变。
