    摘要： A queue number acquiring unit acquires a command queuing number that is the upper limit of the number of process-waiting instructions that can be stored in each of storages that make up a virtual disk for each storage. A minimum queue number selecting unit selects the minimum value of the command queuing numbers of the storages that make up the virtual disk as a minimum queue number. A queue number setting unit sets the selected minimum queue number as the command queuing number of the virtual disk that includes the storage device of which the command queuing number is selected as the minimum queue number for each virtual disk.

    摘要： A apparatus for controlling a first storage and a second storage, has a controller for receiving a write command and a read command sent out from a host and for sending out the write command and the read command to the first storage and the second storage, a determining unit for sending out a request corresponding to the write command to the first storage and the second storage, for receiving a first response corresponding to the request from the first storage and a second response corresponding to the request from the second storage, and for determining one of the storages on the basis of each of response times, a first writing unit for writing data into the determined storage, and a second writing unit for writing the data written in the determined storage into the other storage after writing the data into the determined storage by the first writing unit.
