To support appropriate selection of a configuration of a cloud system. A computer system includes a processor, a storage apparatusand an input/output apparatus, the storage apparatusstores at least configuration condition informationindicating evaluation values for system configurations that can be constructed on cloud, the input/output apparatusaccepts a configuration request indicating a condition for a system configuration to be constructed on the cloud, the processorobtains an evaluation value corresponding to the configuration request, compares the evaluation value corresponding to the configuration request with the evaluation values of the configuration condition information and determines a candidate for a system configuration to be proposed on the basis of a result of the comparison, and the input/output apparatusoutputs the candidate for the system configuration to be proposed.

Recommendation of candidate system configuration to be constructed on a cloud based on configuration request

An arrangement combination of a backup repository satisfying an arrangement constraint rule is calculated based on business system configuration information related to a configuration of a business system server included in a management target, backup repository configuration information which is information related to a configuration of a repository server for storing the backup data, input backup setting information, and the arrangement constraint rule for determining an arrangement of backup data according to a backup purpose, Estimated are a processing time of predetermined backup for an arrangement of the backup repository and a processing time of predetermined restoration for an arrangement of the backup repository and a restoration purpose. The combination in which the processing times of the backup and the restoration satisfy a target backup completion time and a target restoration processing time included in the input backup setting information is derived among arrangement combinations of the backup repository.

Backup management system, management calculator, and non-temporary computer-readable recording medium

A computer system comprises: a server transmitted an input/output processing request; a storage apparatus comprising input/output processing units capable of processing the input/output processing request, and the logical volumes; a management computer managed the storage apparatus; and a particular processor managed a particular resource group, wherein the particular processor is configured to: calculate a load balancing plan when a load on a first resource comprised in the particular resource group is excessive, to distribute a part of the load on the first resource to a second resource comprised in the particular resource group; output the load balancing plan in a manner that allows the load balancing plan to be displayed; and distribute the load on the first resource to the second resource by following the load balancing plan, when an instruction to execute the load balancing plan is received as a result of outputting the load balancing plan.

Computer system and load leveling program

A system management method for a management computer coupled to a computer system, the computer system including a plurality of computers, an operations system being built thereon the computer system, the operations system including a plurality of task nodes each having allocated thereto computer resources, the system management method including: a step of analyzing a configuration of the computer system for specifying a important node, which is an important task node in the operations system; a step of changing an allocation amount of the computer resources allocated to the important node for measuring a load of the operations system; a step of calculating a first weighting representing a strength of associations among the plurality of task nodes based on a measurement result of the load; and a step of specifying a range impacted by a change in the load of the important node based on the calculated first weighting.

System management method, management computer, and non-transitory computer-readable storage medium

In performance estimation when the configuration of a computer system is changed, the influence, on performance, of a temporary increase in load to a computer system due to reallocation of a process request allocated to a degenerated server to another server as a result of server degeneration is taken into consideration. In an embodiment, an information processing device which evaluates the performance of the computer system estimates the performance of the computer system when operation of a server included in the computer system is stopped based on the throughput required for the server at the time of operation stop and outputs the estimated performance of the computer system.

Performance evaluation method and information processing device

A plurality of process content is retained, said process content including identifiers of a plurality of part content included in each process and information which denotes dependencies among the plurality of part content. When information is inputted which designates a first process and the part content of a problem portion which is included in the first process, a process similar to the first process is retrieved. On the basis of whether there is a change in any of the plurality of part content which is included in the retrieved process, an evaluation value of the retrieved process is either incremented or decremented, and the information relating to the plurality of processes is outputted on the basis of the evaluation value.
