    • The present invention makes it possible to dynamically and optimally change QoS while taking the balance of a system as a whole into consideration. With the present invention, communications parameters comprising band allocation information with respect to a plurality of interfaces of communications paths are set at a management device, and a host device, a switch device, and a storage device communicate based on the communications parameters that have been set. Then, in the system operation stage, the management device or the switch device acquires statistical information comprising band usage amounts with respect to the communications paths among a port of the host device, a port of the storage device, and a port, of the switch device, changes, based on the statistical information, the band allocation that has been set with respect to the plurality of interfaces, and, further, determines whether or not the band allocation as changed is appropriate with respect to the system (see FIG. 9).
    • 本发明使得可以在考虑整个系统的平衡的同时动态地和最佳地改变QoS。 利用本发明,在管理设备处设置包括关于通信路径的多个接口的频带分配信息的通信参数,并且主机设备,交换机设备和存储设备基于已经被通信的通信参数进行通信 组。 然后,在系统运行阶段,管理装置或交换机装置获取关于主机装置的端口,存储装置的端口和端口之间的通信路径的频带使用量的统计信息 设备,基于统计信息,已经针对多个接口设置的频带分配进行改变,并且还确定相对于系统是否适合改变的频带分配(参见图9 )。

    • A motor controller is provided. The motor controller includes a motor drive unit that drives a plurality of motors; a thermal shutdown unit that is provided in the motor drive unit and that stops the plurality of motors in the case of an overload; a lock signal generation unit that generates a lock signal corresponding to a respective one of the plurality of motors when a rotational speed of the respective motor reaches a threshold speed set for the respective motor; and an operation determination unit which, when the lock signal generation unit interrupts lock signals for all of the plurality of motors, determines that thermal shutdown unit has operated.
    • 提供电机控制器。 马达控制器包括驱动多个马达的马达驱动单元; 热关断单元,设置在马达驱动单元中,并且在过载的情况下停止多个马达; 锁定信号产生单元,当各个电动机的转速达到为各个电动机设定的阈值速度时,产生与多个电动机中的相应电动机相对应的锁定信号; 以及操作确定单元,当锁定信号生成单元中断所有多个电动机的锁定信号时,确定热关闭单元已经操作。
