Device allocation utilizing job information, storage system with a spin control function, and computer thereof

A computer running a program to execute a data processing job and coupled to a storage system, the storage system having disk drives each of which includes a disk whose spinning can be controlled, the storage system providing logical volumes to the computer by allocating the storage areas to the logical volumes, comprising:

• an interface coupled to the storage system;
• a processor coupled to the interface;
• and
• a memory coupled to the processor,
• wherein the memory stores:
• logical volume information containing a use attribute which is defined to each of the logical volumes to indicate to which one of processing performance and power consumption the logical volume gives priority;
• and
• job information containing an execution order of the job and a load attribute of the job, wherein the load attribute includes either a first load attribute which indicates that load of computation processing by the computer has high priority in the job execution, or a second load attribute which indicates load of reading or writing data to the logical volumes has high priority in the job execution, and
• wherein the processor is configured to:
• select, before executing the job, a logical volume for storing a file that is used temporarily in the execution of the job based on the load attribute of the job and the use attribute of the logical volume;
• send to the storage system a request to allocate a storage area to the selected logical volume along with the use attribute of the selected logical volume;
• and
• notify the storage system of completion of the job when the execution of the job is finished.

A computer system comprising:

• a computer that executes a data processing job by running a program;
• and
• a storage system where data read or written by the computer is stored,
• wherein the computer has a first interface coupled to the storage system, a processor coupled to the first interface, and a memory coupled to the processor,
• wherein the storage system has a second interface coupled to the computer, a storage controller coupled to the second interface, and disk drives in which data read or written by the computer is stored,
• wherein the storage controller provides logical volumes to the computer by allocating the storage areas to the logical volumes,
• wherein the storage controller controls spinning of disks in the disk drives, wherein the memory stores:
• logical volume information containing a use attribute which is defined to each of the logical volumes to indicate to which one of processing performance and power consumption the logical volume gives priority;
• and
• job information containing an execution order of the job and a load attribute of the job, wherein the load attribute includes either a first load attribute which indicates that load of computation processing by the computer has high priority in the job execution, or a second load attribute which indicates load of reading or writing data to the logical volumes has high priority in the job execution,
• wherein, before executing the job, the processor selects a logical volume for storing a file that is used temporarily during the execution of the job based on the load attribute of the job and the use attribute of the logical volume,
• wherein the processor sends to the storage system a request to allocate a storage area to the selected logical volume along with the use attribute of the selected logical volume,
• wherein, upon reception of the request to allocate a storage area to the selected logical volume, the storage controller selects which storage area to allocate to the selected logical volume based on the use attribute of the selected logical volume,
• wherein the storage controller allocates the selected storage area to the selected logical volume,
• wherein the processor notifies the storage system of completion of the job when the execution of the job is finished, and
• wherein, when notified of the completion of the job, the storage controller releases the storage area that has been allocated to the selected logical volume.
