    • Provided is a priority control method for controlling a priority of data transmission in a computer system including a storage system that has a plurality of volumes, a host computer that uses the volumes, a management computer that sets a priority of data transmission between each volume and the host computer, and a network that is composed of a network device controls the priority of data transmission and provides a connection path between the storage system and the host computer. Executed in the method are a first step of obtaining from the storage system information on a first priority assigned to each volume in the storage system and a capacity of a cache memory allocated to each volume, a second step of determining a second priority of the volume on the connection path through the network by referring the obtained information, a third step of notifying the host computer of the determined second priority, a fourth step of obtaining identification of the connection path corresponding to the determined second priority of the volume, and a fifth step of setting the obtained identification to the network device.
    • 提供了一种用于控制包括具有多个卷的存储系统的计算机系统中的数据传输的优先级的优先级控制方法,使用该卷的主计算机,管理计算机,其设置每个卷之间的数据传输的优先级, 主机和由网络设备组成的网络控制数据传输的优先级,并提供存储系统与主机之间的连接路径。 在该方法中执行的第一步是从存储系统获得关于分配给存储系统中的每个卷的第一优先级和分配给每个卷的高速缓存的容量的信息,确定卷的第二优先级的第二步骤 在通过参考所获得的信息的通过网络的连接路径上,第三步骤,通知主计算机所确定的第二优先级;第四步骤,获得与所确定的第二优先级对应的连接路径的识别;以及第五步骤 将获得的标识设置到网络设备的步骤。
