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

An SDS node adjusts a physical capacity included in a logical volume provided to a tenant and is to be allocated to the tenant, based on the size of data written from the tenant. An operation management system provides storage to the tenant and adjusts the provided storage to include a node and a capacity allocation and recovery system. The node provides the logical volume of the storage to the tenant, receives writing of data to the logical volume from the tenant, and writes the received data to a region included in the storage and having the physical capacity allocated to the tenant. The capacity allocation and recovery system determines a physical capacity to be interchanged based on the size of the logical volume, the size of the written data, and the physical capacity allocated to the tenant, and notifies information on the determined physical capacity to the node.

Operation management system and operation management method

A cloud computing system is provided in order to meet the requirement for efficiently processing a large amount of information, and to meet the requirement for stable performance. This is achieved by a computer system including a user terminal, a plurality of servers connected to the user terminal through a network to provide services to the user terminal, and a management device for managing a server for providing a service to the user terminal. In the computer system, the user terminal transmits the boot information indicating one boot mode among fix boot, first boot, and not-first boot, to the management device. The management device selects a server for providing a service to the user terminal based on the boot information. Then, the selected server provides the service to the user terminal.

System for selecting a server from a plurality of server groups to provide a service to a user terminal based on a boot mode indicated in a boot information from the user terminal

A computer in which functions of its resources are divided to realize a plurality of virtual computersand which includes a plurality of physical devices. A managing unit of the computer, when usage of a virtual device has changed, selects a physical device compatible with the virtual device from physical devices usable for a control scheme and makes the physical device be associated with the virtual device and changes the control scheme of the virtual device, thereby achieving the control of devices in the virtual computers, where a plurality of control schemes including a shared scheme and a dedicated scheme are switched.

Computer, control method for virtual device, and program thereof

A first computer stores a correspondence between a virtual channel and a physical channel (s) in physical channel information and transmits the correspondence between the virtual channel and the physical channel (s) to a second computer having a virtual network interface to which a data transmission instruction is addressed. Upon receiving the correspondence between the virtual channel and the physical channel(s), the second computer stores the received correspondence in the physical channel information. The first computer transmits data in accordance with the data transmission instruction, using one or more physical channels associated with the virtual channel, based on the correspondence stored.

Method for configuring virtual network and network system

A hypervisor prepares a guest region identifier (RID)-physical region identifier (RID) mapping table for dynamically registering and managing items and performs RID conversion using the guest RID-physical RID mapping table. When the mapping table is used, since it is unnecessary to provide a specific information area representing logical partitions (LPARs) corresponding to respective guests in an RID to be converted, there is no limitation concerning the number of LPARs and a problem in operation can be eliminated.

Computer virtualization apparatus and program and method therefor

The invention relates to a network management method wherein: a service management equipment holds the mapping of services and virtual networks as management information; a managed server sends an advice to a VLAN management equipment when its status changes; and the VLAN management equipment receives the advice and refers to the information contained in the advice to thereby identify the managed server and the connection port of a network switch, and configures a virtual network belonging to the identified port of the network switch. The method alleviates the task of reconfiguration associated with the adding or deleting of servers.
