Abstract:
1. A power estimating method in a computer system including a management computer and a storage system connected to the management computer and a host computer, wherein the management computer includes a first interface connected to the storage system, a first processor connected to the first interface, and a first memory connected to the first processor, wherein the host computer includes a second interface connected to the storage system, a second processor connected to the second interface, and a second memory connected to the second processor, wherein the storage system includes at least one third processor controlling read and write of data to and from a plurality of disk drives, a control memory connected to the third processor, a management interface connected to the management computer, a host interface connected to the host computer, a disk interface connected to the disk drives, and a cache memory unit temporarily storing data, wherein the third processor, the management interface, the host interface, the disk interface, and the cache memory unit are connected to each other, wherein the cache memory unit includes a plurality of third memories and a memory controller controlling the plurality of third memories, wherein the control memory stores a storage control program for controlling the storage system and control data used to control the storage system, wherein the storage control program includes a power estimating program for estimating power, wherein the control data includes incremental power consumption information indicating power consumption increments of the disk drives, the cache memory unit, and the third processor when the storage system is operating, wherein the storage system wherein the incremental power consumption information includes information on power consumption increments of the disk drives according to access types which include random access and sequential access to the logical storage-volumes, wherein the method comprises: allowing the third processor to calculate operating times in the each access type based on access time in which at least one access corresponding to the access type is issued to the logical storage-volume exists, allowing the third processor to calculate operation rates of the disk drives for the each access type to the logical storage-volumes from the operating times of the disk drives for access to the logical storage-volumes; allowing the third processor to calculate power consumption increments of the disk drives for the each access type to the logical storage-volumes by access directions from the incremental power consumption information in which each access type has each incremented power consumption and the calculated operation rates of the disk drives; and allowing the third processor to transmit the calculated power consumption increments of the disk drives for the each access type to the logical storage-volumes to the management computer.
