摘要： A plurality of command storage areas respectively corresponding to a plurality of priorities and storing I/O commands in a storage control apparatus are common to a plurality of ports and a plurality of processors. Here, regardless of which port receives an I/O command, the I/O command is stored in a command storage area corresponding to a priority which is given to the I/O command. The plurality of processors run the I/O commands in the plurality of command storage areas so that an I/O command with a higher priority is run more often within a given period of time.

摘要： To provide a storage system that can control both the number of commands activated per unit time and the response time of each command activated in accordance with the priority level of command. The storage system comprises a queue corresponding to each priority of command and an activation order control part. A command that the storage system receives from a host computer is accumulated in the queue corresponding to the priority specified from the command. The activation order control part decides, for each queue, the number of activation object commands that are the commands to be activated among a plurality of commands accumulated in the queue, based on the priority corresponding to the queue. And the activation order control part decides the activation order of the activation object commands, based on the activation object command number decided for each queue, so that the average value of logical response time of the activation object command may be shorter at the higher priority. The activation object command is activated in accordance with the decided activation order.

摘要： A computer system of the present invention can adjust the execution frequencies of a command issued from a host and a command issued from a storage. An external manager disposed in the host configures a priority for a host command issued from a command issuing module inside the host. An internal manager disposed in the storage configures a priority for an internal command issued from a command issuing module inside the storage. The internal manager adjusts the execution frequency of the host command and the execution frequency of the internal command based on the host command priority and the internal command priority.
