摘要:
A virtual system control apparatus includes a configuration information storage device that stores configuration information for operational systems of virtual systems; a first virtual machine image storage device that stores virtual machine images for the operational systems of the virtual systems; a configuration change information storage device that stores configuration change information that represents configuration information concerning difference between the operational system and a test system of the virtual system; a second virtual machine image storage device that stores virtual machine images for the virtual machine relating to the difference; and a controller. Thus, by adopting data configuration of the operational system and the test system, it becomes possible to easily and smoothly switch the virtual system between the operational system and the test system.
摘要:
A master calculator assigns a series of processing groups to a communicable worker calculator. The master receives information about an execution time and a waiting time from the worker calculator for the series of processing groups. The computer acquires the time elapsed between transmitting the processing group transmitted to the worker calculator and receiving the execution result of the processing group from the worker calculator. The master calculates the communication time required for communication with the worker calculator on the basis of the information received and the elapsed time acquired. The master calculates the number of processings to be assigned to the worker calculator on the basis of the communication time calculated. The master generates a processing group to be assigned to the worker calculator on the basis of the number of processings calculated, and transmits the processing group generated to the worker calculator.

A computer executes a distributed processing program. The computer is a master computer that uses communicable worker computers to execute distributed processing on plural jobs. The computer determines an allocation destination of the jobs from the worker computers. The computer calculates the number of jobs to be allocated to the allocation destination based on the processing performance and the communication time (delay time) taken for communications with a worker computer. The computer generates a job group to be allocated to the allocation destination on the basis of a calculation result obtained. The computer transmits a processing request of the generated job group to the allocation destination.
摘要:
In a resource brokering apparatus, a setting unit sets a value of each service, and a detecting unit detects whether resource nodes are insufficient when a request for one service is received by a receiving unit. When it is insufficient, a determining unit determines whether a first value of a resource node used for one service is higher than a second value of the resource node which is currently used for another service. If the first value is larger than the second value, the other service is switched to the one service.

A control method includes allocating a plurality of virtual disks to a virtual storage allocated to a physical storage, associating data with one of the plurality of virtual disks which has been instructed to store the data and storing the data in the physical storage, and selecting, by a processor, one of the plurality of virtual disks as a data movement target virtual disk from which data is to be moved in accordance with a network bandwidth of the physical storage corresponding to the virtual storage when free space in the virtual storage exceeds a threshold value.
摘要:
An apparatus for evaluating a change of an existing system to a modified system by using a test system including a subsystem having the same configuration with either of the existing subsystem and the modified system includes: a memory for storing configuration information of the test system and test information; and a processor for executing a process including: activating the test system to execute test on the subsystem, collecting test information from the test system, and storing the test result information while the subsystem has the same configuration as the existing system; confirming the test system has been modified; and activating the test system to execute test on the subsystem, collecting test result information from the test system, and storing the test result information while the subsystem has the same configuration as the modified system.
摘要:
An internet-protocol address assignment control apparatus obtains, via an interface provided in a first communication device, a first unique number for a first interface provided in a server apparatus connected to the interface provided in the first communication device and a second unique number for a second interface provided in the server apparatus connected to an interface provided in a second communication device. The apparatus stores, in a storage, the obtained second unique number for the second interface provided in the server apparatus on a basis of the first unique number for the first interface provided in the server apparatus.
摘要:
The I/O performance measurement unit of Hypervisor measures latencies of I/O process requests to virtual disks, and reports the average value of the latencies to the I/O performance information collection unit of the management server. The provision destination determination unit sets, as a storage unit to which a virtual disk is to be allocated, that is a storage unit having the smallest average value of the latencies among storage units to which virtual disks have been provided.
