The cluster system including a generator that generates reference information in which an estimated consumption power and an estimated performance of a cluster including two or more candidate nodes among the plurality of nodes when the candidate nodes are assumed to be operated at respective load setting values are associated with each other for each of a plurality of combinations of the respective load setting values of the candidate nodes; a load setting value selector that selects a combination of the respective load setting values of the candidate nodes, the combination leading to the estimated performance satisfying a required performance for the cluster and having the lowest consumption power, by referring to the reference information; and an operation controller that operates the candidate nodes at the selected combination of the load setting values. This configuration satisfies the required performance and also reduce the consumption power.

Cluster system, controller, method for controlling, and computer-readable recording medium having stored therein controlling program that operate node at the combination of the respective load setting values that satisfy required performance and lowers power consumption

A testing server performs a test to check whether servers properly execute failover. The testing server includes a generation unit, a transmitting unit, a testing unit, a restoring unit, a judgment unit, and a power control unit. The generation unit generates an image file of an OS. The transmitting unit transmits the image file to to-be-tested servers. The testing unit injects a simulated fault into a server among the servers to which the image file is transmitted and performs a test. The restoring unit, each time the testing unit performs a test, restores a status of the to-be-tested server to a pre-failover status. The judgment unit judges whether the restoring unit properly restores the status. The power control unit, when the judgment unit judges that the status of the to-be-tested server is not properly restored, turns off power of the to-be-tested server and turns on the power again.

Testing server, information processing system, and testing method

An information processing apparatus includes a memory, and a processor coupled to the memory. The processor is configured to collect information including a diagnosis history regarding a plurality of components of the information processing apparatus in application processing by the information processing apparatus, determine priority level settings from among a plurality of offline diagnoses with regard to each of the components, prioritize offline diagnosis of the information processing apparatus based on the information and the priority level settings, and perform the plurality of offline diagnoses with regard to the components at a time of the offline diagnosis of the information processing apparatus based on the priority level settings.
