发明名称 Storage control device and storage control method
摘要 A first processor is configured to acquire measurement values of plural types of processing index values each indicating a state of processing loads on a storage control device, and plural types of access index values each indicating a state of loads of an access process performed for each of plural pieces of data stored in a first storage device. The first processor is configured to select a first access index value corresponding to a first processing index value when the acquired measurement value of the first processing index value exceeds a threshold value. The first processor is configured to move a first piece of data from the first storage device to a second storage device. The acquired measurement value of the first access index value for the first piece of data is higher than the acquired measurement value of the first access index value for any other piece of data.

主权项 1. A storage control device that controls access to a first storage device of a plurality of storage devices, the storage control device comprising: a first processor configured to: acquire measurement values of plural types of processing index values each indicating a state of processing loads on the storage control device, and plural types of access index values each indicating a state of loads of an access process performed for each of plural pieces of data stored in the first storage device, the plural types of access index values including a processing time during access to each of the plural pieces of data, the processing time corresponding to an amount of time from reception of an access request to a response of access completion;specify a first access index value corresponding to the processing time when the acquired measurement value of the first processing index value exceeds a threshold value set for the first processing index value, the first processing index value being one of the plural types of processing index values, the processing time being one of the plural types of access index values; andmove a first piece of data from the first storage device to a second storage device of the plurality of storage devices, access to the second storage device being controlled by a first control device different from the storage control device, the acquired measurement value of the processing time for the first piece of data, among the plural pieces of data, being higher than the acquired measurement value of the processing time for the plural pieces of data other than the first piece of data.
