    • In a packet transport network, to determine a path route in which a bottleneck does not occur with a small amount of calculation, provided is a network system, including data transfer devices and a management computer, each of the data transfer devices including IFs, in which the management computer is configured to: store remaining bandwidth information on the each of the IFs; select one of bandwidths; judge, based on the remaining bandwidth information and the selected bandwidth, whether or not the each of the IFs is usable; determine a route candidate though which data is transferred, bypassing the each of the IFs which has been judged to be unusable; judge, based on the remaining bandwidth information, whether or not continuity of the IF through which the route candidate passes is possible; and allocate the route candidate, the continuity of which is possible, to a new path.
    • 在分组传输网络中,为了确定在少量计算中不出现瓶颈的路径路径,提供了包括数据传输设备和管理计算机的网络系统,每个数据传输设备包括IF,其中 管理计算机被配置为:将剩余带宽信息存储在每个IF上; 选择一个带宽; 基于剩余带宽信息和所选择的带宽判断每个IF是否可用; 确定通过哪个数据被传送的路由候选,绕过被判断为不可用的每个IF; 基于剩余带宽信息判断路由候选者通过的IF的连续性是否可能; 并将其连续性的路由候选分配给新的路径。

    • In a cluster type NAS, it is necessary to copy file data between disk devices of servers upon migration of a file system or a part of the file system. A server includes a control table for managing a file system or a part of the file system, and a mapping table for managing a relation between a logical device of a disk subsystem and a logical unit recognized by a server, and in response to an instruction to execute migration of the file system from a first server to a second server, the mapping table is referenced to send an instruction to update the relation between the logical device and the logical unit to the second server, and the second server newly recognizes a logical unit and updates a management server identifier of the control table.
    • 在集群类型NAS中,有必要在文件系统或文件系统的一部分迁移时将文件数据复制到服务器的磁盘设备之间。 服务器包括用于管理文件系统或文件系统的一部分的控制表,以及用于管理磁盘子系统的逻辑设备与由服务器识别的逻辑单元之间的关系以及响应于指令的映射表 为了执行文件系统从第一服务器到第二服务器的迁移,参考映射表发送指令以将逻辑设备和逻辑单元之间的关系更新到第二服务器,并且第二服务器重新识别逻辑 单元并更新控制表的管理服务器标识符。
