摘要： An administrator instructs creation of a volume to a virtual storage device and registration of a host port for providing access permission to the volume. The virtual storage device searches a candidate of a physical storage device capable of reaching the host port and a candidate of the target port based on the access permission information, and creates a distributed volume astride the candidate physical storage device. The distributed volume is composed of a plurality of partial volumes, and the partial volumes inherit the functions of the storage device and the access permission information set for the distributed volume. The virtual storage device distributes an access permission to the physical storage device, constitutes the access permission information of the host port and the volume with respect to the candidate target port, and registers the access permission information of the host port and the target port to the SAN switch.

摘要： Even when there is some degree of variation in the characteristics among components constituting a polyphase motor and a driving circuit therefor, current control signals of respective phases being input to the drive circuit have their amplitude finely adjusted by an amplitude control circuit, so that amplitude is uniform among armature currents of respective phases that are ultimately output from the drive circuit. The amplitude adjusting circuit is configured by gain variable amplifiers, for example. Thus, rotation fluctuation and vibration of the polyphase motor can be reduced.
