摘要： In the storage-based snapshot creation, a block-selection specifying unit provided on a NAS processing unit specifies a block, which becomes necessary for the generation of snapshot data, to a specified-block analyzing unit within a disk apparatus. Moreover, a disk controller generates the snapshot data on the block specified as the snapshot target, while making an inquiry to the specified-block analyzing unit. This makes it possible to create the snapshot in a storage-capacity reduced manner, and to specify the snapshot creation in a partition, file, or directory unit.

摘要： In a distributed file system, when a user requests a computer to create a distributed file, a management computer acquires a list of computers complying with an allocation rule selected by the user from allocation rules taking the performance, security level, reliability level and utility rate into consideration. When the user requests the computer to access the distributed file, on the other hand, the partial files and the server information are collected from each computer. Each computer evaluates the allocation of the partial files based on the selected allocation rule and the server information from each computer, and if required, selects a destination computer and instructs the partial files to be moved to the destination computer.

摘要： The object of the present invention is to improve an access efficiency in a distributed environment. When a user “foo” access a file “file_1a” stored in a storage node SN1 under the control of a control node CN1 from a client CLN3 via a control node CN3 as shown by the solid lien arrow in the figure, a record of the access is accumulated in an access history of the control node CN1. If the control node CN1 refers to the access history and detects the frequent accesses from the control node CN3, it replicates or migrates the file “file_1a” to a storage node SN3 controlled by the control node CN3 as shown by the bold line arrow. The replication is performed if another device has accessed the file. Otherwise the migration is performed.
摘要翻译：本发明的目的是提高分布式环境中的访问效率。当用户“foo”通过控制节点CN 3从客户端CLN 3访问在控制节点CN 1的控制下存储在存储节点SN 1中的文件“file_1a”，如图中的固态留置箭头所示，在控制节点CN 1的访问历史中累积访问记录。如果控制节点CN 1参考访问历史并且检测到来自控制节点CN 3的频繁访问，则它将文件“file_1a”复制或迁移到由控制节点CN 3控制的存储节点SN 3，如粗体线箭头。如果另一个设备已访问该文件，则执行复制。否则执行迁移。
