Abstract

A storage management server collects, stores and displays positions, temperatures and temperature threshold values of physical storage devices from a storage apparatus. It collects, stores and displays positions and power consumptions of variable factor generation sources which are factors that cause the physical storage devices to vary in operation environments, and also calculates the influenceability by variable factor generation sources against the physical storage devices and affected temperatures thereof. It compares the temperature of a given physical storage device to a temperature threshold value of this physical storage device or compares it to an affected temperature thereof due to the variable factor generation sources, thereby moving, for data transfer, an operation position of physical storage device based on a comparison result at such time.

Claims

1. A storage management server coupled to a storage apparatus having physical storage devices and dependent operational devices rendered operative depending on activation of said physical storage devices, comprising:

a storage unit storing an operation environment threshold value;

a control device; and

a display device,

wherein said control device controls to collect operation environment value of physical storage devices provided in said storage apparatus from said storage apparatus, and determines whether said operation environment value collected exceeds said operation environment threshold value,

wherein said control device controls to collect energy consumption amounts of physical storage devices and dependent operational devices from said storage apparatus, calculates a total energy consumption amount in said storage apparatus according to the collected energy consumption amounts of said physical storage devices and said dependent operational devices, and

wherein, when a result of the determination indicates that there is a certain physical storage device with its collected operation environment value exceeding said operation environment threshold value, said display device displays warning information indicating operation environment value being exceeded said operation environment threshold value, and displays said total energy consumption amount in said storage apparatus.

2. A storage management server according to claim 1,

wherein said display device displays a maximal value of said operation environment values stored in the storage unit.

3. A storage management server according to claim 2, further comprising:

a input device receiving a position range,

wherein said controller identifies at least one of said physical storage device or at least on of said dependent operational device belonging to said position range, and

wherein said display device displays with visual emphasis an image indicating said at least one of said physical storage devices or said at least one of said dependent operational devices.

4. The storage management server according to claim 2, further comprising:

a input device receiving a request designating a certain logical storage region, which is one of logical storage regions provided by said storage apparatus with said physical storage devices,

wherein said storage unit stores a correspondence between said logical storage regions and said physical storage devices,

wherein said controller identifies a part of said physical storage devices corresponding to said certain logical storage region, and

wherein said display device displays with visual emphasis an image indicating said part of said physical storage devices.

5. A storage management server according to claim 4,

wherein the storage unit stores positions of said physical storage device, operation environment influence value which indicates an influence of an operation environment when a first logical storage region which is one of said logical storage regions is transferred from a first physical storage device which is one of said physical storage devices to a second physical storage device which is another one of said physical storage device,

wherein said controller calculates an affected operation environment value, based on said positions of said physical storage device, said operation environment value, and said operation environment influence value,

wherein said controller calculates an total after-transfer energy consumption amount, based on said transfer of said first logical storage region, said energy consumption amounts,

wherein said display device displays warning information indicating which an operation environment value exceeds said operation environment threshold value after said transferring of said first logical storage region is executed, when said affected operation environment value exceeds said operation environment threshold value, and

wherein said display device displays said position of said physical storage devices and said total after-transfer energy consumption amount in said storage apparatus.
