摘要:
When migrating a virtual server between a plurality of physical servers, a pre-migration connection relationship between the virtual server and a storage area used by the virtual server is maintained after the migration of the virtual server by using a cooperative mechanism between a plurality of storage apparatuses even if the storage area used by the virtual server is migrated between the plurality of storage apparatuses. A computer system and virtual server migration control method for the computer system is described.

Provided is a method of using a dynamic chunk allocation function to efficiently carry out data volume migration. A storage apparatus according to the present invention includes first and second storage units and divides a storage extent in the second storage unit into chunks to add the chunks to a chunk pool to dynamically allocate the chunks in the chunk pool to a newly created logical data volume (see FIG. 3).

摘要:
A management system outputs catalog data, which has been created based on catalog-source data comprising data showing at least an application of a relevant resource with respect to each of multiple providable resources, and which shows the respective applications of the multiple resources, and receives a selection of a resource to be provided from the multiple resources. The management system provides the selected resource as a provided resource, and determines, based on a performance threshold configured with respect to the application of the provided resource, whether or not a performance measurement value, which relates to the processing performance of a network service using the provided resource and which can be monitored by the management system, is normal.

It is an object of the present invention to provide a technique that can comprehensively manage plural kinds of network addresses allocated to virtual computers. In various embodiments, a MAC address, an IP address, and virtual communication interface identification information are allocated anew to a virtual computer to be created anew and the MAC address, the IP address, and the virtual communication interface identification information are set to be unable to be allocated anew.

摘要:
A computer system comprising a storage device including a copy pair of a copied volume and a host computer is provided. The management computer detects a change in the state obtained by monitoring the state of the copy pair, and according to the result of detection, changes the configuration of a cluster constituted by a virtual machine using data stored in the volume, and a host computer using the volume.
摘要:
A computer system in an embodiment of this invention comprises a plurality of host computers in which a plurality of host programs are executed, a plurality of storage systems including a plurality of volumes provided to the plurality of host programs, and a management system. Each of the plurality of host programs is located at a port of a host computer. Each of the plurality of volumes is located at a port of a storage system. The management system obtains information on bandwidths of a plurality of paths included in a data communication network among the plurality of storage systems and the plurality of host computers. The management system determines priority levels of individual candidate ports for new location of at least either one of a first host program and a first volume with reference to the information.
