Abstract: A resource allocation system calculates a performance ratio and a cost for each of a plurality of service tiers. For each of the service tiers, the performance ratio is a ratio of the intended performance to an agreement performance, the agreement performance is a performance that serves as a reference performance of the service tier, the intended performance is a performance calculated for the service tier, and the cost is based on a used capacity of an allocated storage resource among the storage resources belonging to the service tier. The system displays a service tier map that has an axis corresponding to the performance ratio and a second axis orthogonal to the axis and corresponding to the cost. A display object is placed, for each service tier, at a position according to the calculated performance ratio and the calculated cost of the service tier on the service tier map.

Abstract: A performance analysis method of a computer system using a management computer. The management computer includes: a processor; and a memory device in which a program to be executed by the processor is stored. The computer system is constituted by a plurality of resources. The processor divides the plurality of resources into a plurality of resource groups based on a correlation of changes in performance data between the resources, and analyzes the performance data for each of the divided resource groups.

Abstract: With respect to each of one or more entities, a computer sets a sum of an upper-limit NW send quantity and an upper-limit write quantity to a level equal to or lower than an allocation send quantity that is a send quantity allocated for the entity concerned. With respect to each of the one or more entities, the upper-limit NW send quantity is an upper-limit value of the NW send quantity that is the quantity of data to be sent per unit time via an NW I/F of the computer. With respect to each of the one or more entities, an upper-limit write quantity is an upper-limit value of a write quantity that is the quantity of data to be written per unit time to a logical volume recognized by the entity concerned.

Abstract: A computer system according to the present invention is composed of a server 200 having a flash memory drive 204 for cache, a storage system 260 having storage tiers composed of an SSD 267 and an HDD 268, and a management server having a page tier determination program 503 for determining the storage tier to which data is to be stored. The page tier determination program 503 migrates data having a high read access rate out of the pages having a high cache rate to the flash memory drive 204 to a storage tier of the HDD 268, and confirms so that data is not stored in a duplicated manner to the flash memory drive 204 and the SSD 267. Further, the data having a relatively high write access rate is migrated to the storage tier of the SSD 267 so as to prevent deterioration of write process performance.

Abstract: A method of tier management of data comprises performing a tier migration log information setup process which includes selecting an area specified by a virtual volume address and a logical volume address; determining a destination tier for the area based on a number of accesses to the area; and updating a tier migration log information by inputting the determined destination tier and a time; and performing a process using the tier migration log information to determine whether to migrate a specific area which includes loading a tier migration log from the tier migration log information by selecting a specific time; checking if a current tier of the specific area equals a destination tier specified by the tier migration log; and if the current tier is not equal to the destination tier, migrating the specific area to the destination tier.
