    • There is disclosed a high speed switching method for a disk image delivery system fail-over. A management server sends a disk image of an active server in advance to a standby server. When receiving a report that the active server has failed, the management server judges whether or not it is possible for the standby server to perform the service of the failed active server based on service provision management server information held by the management server and if possible, instructs the standby server to perform the service of the active server. Even if the disk image delivered in advance is different from the disk image of the failed active server, switching of is the service to the standby server can be performed more quickly through resetting the setting values of unique information and installing the additional pieces of software on the standby server by the management server than redelivering an appropriate disk image.
    • 公开了一种用于磁盘映像传送系统故障切换的高速切换方法。 管理服务器事先将活动服务器的磁盘映像发送到备用服务器。 当接收到活动服务器发生故障的报告时,管理服务器根据管理服务器所保持的服务提供管理服务器信息来判断备用服务器是否可以执行故障活动服务器的服务,如果可能, 指示备用服务器执行活动服务器的服务。 即使预先提供的磁盘映像与故障的主动服务器的磁盘映像不同,切换是通过重新设置唯一信息的设置值并将其他软件安装在 备用服务器由管理服务器重新提供适当的磁盘映像。

    • A method of controlling a virtual machine, including: detecting a predetermined trigger by a management server; acquiring a relationship between a virtualization unit and a virtual machine operated on a physical computer; specifying a virtual machine as a migration target based on preset trigger definition information; determining a physical computer of a migration destination based on a preset first control pattern to generate a first plan to migrate the virtual machine as the migration destination; transforming the first control pattern to a second control pattern; generating a second plan to migrate the virtual machine as the migration destination; performing arithmetic an evaluation value of the first plan and an evaluation value of the second plan; selecting one of the evaluation values meeting a predetermined condition as an execution plan; and migrating by the management server the virtual machine as the migration target based on the selected execution plan.
    • 一种控制虚拟机的方法,包括:通过管理服务器检测预定的触发; 获取虚拟化单元和在物理计算机上操作的虚拟机之间的关系; 基于预设触发器定义信息指定虚拟机作为迁移目标; 基于预设的第一控制模式确定迁移目的地的物理计算机,以生成迁移作为迁移目的地的虚拟机的第一计划; 将第一控制模式转换为第二控制模式; 生成迁移目的地迁移虚拟机的第二计划; 执行第一计划的评估值和第二计划的评估值的算术; 选择满足预定条件的评估值之一作为执行计划; 并基于所选择的执行计划,由管理服务器迁移虚拟机作为迁移目标。
