A system for performing operation management of a machine learning model includes a task-inference ID association unit configured to, on the basis of a system data stream for outputting content of a task performed by a system that calls a machine learning model and a recorded data stream for inputting/outputting data when inference of the machine learning model is processed, calculate, with regard to association between the system data stream and the recorded data stream, the association between the system data stream and the recorded data stream from configuration information representing dependency between the system and the machine learning model.

Machine learning model operation management system and method

A grouping unit, with the use of facility order priority information and facility order rule information, determines a group to which facility orders belong, stores the group in grouping information, performs grouping of facility orders, which do not include a sequential relation in a reverse direction among facility orders, into the same group, performs grouping of facility orders, which include a sequential relation in a reverse direction among facility orders, into a different group, integrates the facility orders grouped in the same group, and sets the integrate facility order as a display facility order of the group.

Information processing device and information processing method

A suitable Tier ratio is determined according to the I/O performance and I/O characteristic of a virtual volume. A storage apparatus which is connected via a network to a host computer which requests data writing comprises storage devices of a plurality of types of varying performance; and a controller which manages storage areas provided by each of the storage devices of a plurality of types by means of storage tiers of a plurality of different types, and which assigns the storage areas in page units to virtual volumes from any of the storage tiers among the storage tiers of the plurality of types according to the data write request from the host computer, wherein the controller monitors performance information which includes I/O characteristic information for each of the virtual volumes and determines the storage tiers corresponding to the performance information thus monitored, and assigns the storage areas in page units to the virtual volumes from the determined storage tiers.
