In the computer system, a storage system provides a storage level virtual volume based on thin provisioning technology, to a physical server on which a virtual machine is defined. The storage system releases the area of the logical volume corresponding to the storage level virtual volume accessed by a virtual machine which is specified to be deleted, on the basis of storage level virtual volume conversion information which is managed by the storage system.

Computer system, computer and method for performing thin provisioning capacity management in coordination with virtual machines

A management server includes a meta rule for identifying an event to be a root cause and a failure recovery method that corresponds to the meta rule for an event capable of occurring in a plurality of node apparatuses, and also displays a cause event to be a root cause of an event detected by the management server, and a method for recovering from this cause event.

Management system for outputting information denoting recovery method corresponding to root cause of failure

In a case where a master virtual machine, which is constructed on the basis of master information for configuring either part or all of a virtual machine, and an individual virtual machine, which is constructed on the basis of individual information that is configured partially or entirely in accordance with the master information, exist as the types of virtual machines that a physical client provides to a user terminal, a security check of a plurality of virtual machines is selectively executed, with respect to each check item, for a virtual machine of the type corresponding to the contents of the check item.

Security management device and method

The present invention achieves data relocation in accordance with a user's policies, in an environment where a plurality of storage devices coexist. The volumes belonging to storage devices A-D are managed virtually integrally. A host recognizes a plurality of storage devices A-D as a single virtual storage device. The user is able to group arbitrarily each volume belonging to the storage system, as a plurality of storage layers-. For example, storage layercan be defined as a high-reliability layer, storage layer, as a low-cost layer, and storage layer, as an archive layer. Each storage layer is constituted by a group of volumes corresponding to respective policies (high reliability, low cost, archiving). The user designates volumes Vand Vto be moved, in group units, and indicates a storage layer forming a movement destination, whereby the data is relocated.

Storage system and data relocation control device

An evaluation system evaluates the suitability of an application in a plurality of types of application execution environments based on the characteristics of this application and the usage of this application by a user. The evaluation system displays information denoting the result of this evaluation.

System and method for evaluating application suitability in execution environment

A management apparatus for managing a computer system stores configuration information of multiple management-target apparatuses based on multiple first information received from multiple management-target apparatuses. The management apparatus, based on the configuration information and multiple additional component application condition information, determines whether or not to use multiple additional component information to acquire multiple second information from the multiple management-target apparatuses. The management apparatus, in a case where a determination to carry out acquisition is made, uses the multiple additional component information to receive the multiple second information from the multiple management-target apparatuses, and based on the multiple second information, either creates or updates the management information of the multiple management-target apparatuses.

Management system and computer system management method

The virtual volume is a virtual logical volume that conforms to Thin Provisioning, and is a logical volume configured from a plurality of virtual areas and used by a plurality of applications. In a case where the storage apparatus receives a write request comprising write-destination information for identifying a write-destination virtual area in the virtual volume, and, in addition, the write-destination virtual area is an unallocated virtual area, the storage apparatus selects a medium, which corresponds to the write to the write-destination virtual area and/or the identification information of the source of this write, from a plurality of media, which have different performances and which are each configured from two or more real areas, and allocates a real area from the selected medium to the write-destination virtual area.

Method for controlling data write to virtual logical volume conforming to thin provisioning, and storage apparatus

According to the present invention, it is possible to rearrange an arrangement unit on an appropriate storage device at a more appropriate timing in a complex computer system. A computer system according to the present invention includes a plurality of storage devices of different performance, and provides a virtual volume, the storage devices allocating a segment of the plurality of storage areas to an arrangement unit, which constitutes the target of a virtual volume, in accordance with the arrival of a write request from the business server, and managing, on the business server, an execution time and a predicted execution time of a job to be executed, and a time at which the storage area segment was allocated to the arrangement unit, inferring the relationship of the arrangement unit and the job from the job execution time and the time at which the storage area segment was allocated, and changing the storage area segment allocated to this arrangement unit to another storage area segment at a time decided based on the specified relationship and the predicted execution time.

Storage management system, storage hierarchy management method, and management server capable of rearranging storage units at appropriate time

An operation management systemalleviates the burden on an administratorwho carries out reappearance monitoring of a failure that occurred in a computer system. The operation management systemdetects one or more detected events occurring in the computer system, and selects a first causal laws codeincluded in a causal laws informationbased on the causal laws informationand the detected event. The operation management system, in a case where the composition of the computer systemhas been changed to eliminate the cause of generation of the detected event, selects a second causal laws codeincluded in a post-change causal laws informationbased on the post-change causal laws informationand the first causal laws code, and notifies the administratorof information related to the selected second causal laws code

Management server and management system

The method comprises and executes constitutional information collection processing of collecting constitutional information of the apparatus, constitutional information of a logical unit which is a logical existence obtained by abstracting the apparatus, constitutional information of the application and constitutional information of the dependency relation of the performance established among the apparatus, the logical unit and the application; performance information collection processing of collecting each performance information of the apparatus, the logical unit and the application; and saturation indication detection processing of analyzing a correlation between a change value with time of the performance information of the apparatus and a change value with time of the performance information of the logical unit having the dependency relation of the performance with respect to the apparatus for a predetermined period, and detecting that the apparatus has the saturation indication, when a correlation coefficient obtained by the correlation analysis is a predetermined threshold value or more.

Method and system for managing apparatus performance

A management system detects a peak time period during which accesses are concentrated on a logical page included in a logical volume, and reallocates this logical page to an appropriate physical page. A management server detects an access variation of each logical volume, and selects a volume with a large access variation as a target volume. The management server measures the access status of each logical page in the target volume, and allocates a logical page to a more appropriate physical page.
