An object of the invention is to quickly and appropriately adjust performance of a storage system. Provided is a storage management system including: a storage system including a plurality of storage nodes; and a management device. The storage node includes a storage device and an instance to which a resource is virtually allocated and that controls access to the storage device. The storage management system further includes an instance management node configured to manage the instance of the storage node. The management device is configured to determine whether a configuration of the resource allocated to the instance of the storage node needs to be changed, and cause the instance management node to change the configuration of the resource allocated to the instance when the configuration of the resource needs to be changed.

Storage management system and storage management method

A processor of each node of a storage system executes rebalancing to transfer a volume between pool volumes for the node in such a way as to equalize throughput of a data input/output process and/or data capacities between the pool volumes making up the pool. When a plurality of external volumes are transferred to a node in the storage system, the storage management apparatus determines a transfer destination node for the volumes and order of transferring the volumes and executes volume transfer in such a way as to equalize throughput of the data input/output process and/or data capacities between the pool volumes making up the pool after completion of or during the volume transfer.

Storage system and data transfer method that suppress a drop in the I/O performance of the storage device caused by a rebalancing

To quickly and appropriately adjust a performance of a storage system. A storage configuration optimization device for managing a storage system including one or more storages implemented by a plurality of SDS nodes includes a virtual CPU. The virtual CPU is configured to receive a request for an execution period and a necessary performance of a project using the storage system, and select, based on consumption information and performance information of a resource of the storage system, one or more change patterns satisfying the request for the execution period and the necessary performance from among a plurality of change patterns indicating configuration changes of the storage system.

System configuration management device, system configuration management method, and system configuration management program

In an information processing system, a plurality of control units (control software) implemented in different storage nodes are managed as a redundancy group, one or more first logical units (SLUs) are associated with the redundancy group, and the plurality of control units included in the redundancy group include an active control unit that processes an input/output (IO) request with respect to the first logical unit, and a standby control unit that takes over the processing when the active control unit fails. A processor (configuration management unit) arranges at least one second logical unit (ALU) in the storage node in which the active control unit exists, and associates the second logical unit with the first logical unit controlled by the active control unit.

Information processing system and configuration management method including storage nodes connected by network

The computer system includes one or more storage devices and a management computer, the management computer includes an information collection unit, an event detection unit, a plan generation unit, and a plan execution unit. The plan generation unit determines a target volume of a change process of a right of control in a plan, a processor of a change source of the right of control, and a processor of a change destination of the right of control, estimates an influence by a change process of the right of control in the plan, and the plan execution unit determines execution time of the plan based on the estimation of the influence and the operation information of the storage devices. As a result, in consideration of the influence by an ownership change process, while the influence applied to usage of a computer system is suppressed, the ownership change process is executed.

Computer system and computer system usage management method

A computer management apparatus including a plurality of nodes, each including a processor and a storage device, and stores a countermeasure result table including a plurality of combinations of an anomaly detection rule, a countermeasure rule which is a countermeasure against an anomaly, and an effect indicating effectiveness of these rules, and the management apparatus includes: an anomaly detection unit that detects an anomaly of the computer system based on information acquired from the computer system and the anomaly detection rule; an execution unit that decides a countermeasure, at which the anomaly has been detected by the anomaly detection unit, on the basis of the detected anomaly, the countermeasure rule, and the effect indicating the effectiveness, and executes the decided countermeasure; and a countermeasure result information setting unit that evaluates a result of the countermeasure and records the result in the effect indicating the effectiveness in the countermeasure result table.

Apparatus and method for anomaly countermeasure decision, execution and evaluation

In a computer system, in a case where a throughput upper limit value is set as upper limit value 1, a throughput limit notification program executed by a storage device gives a notification to a storage management device when a throughput of a logical volume reaches the upper limit value 1. In response to this notification, a throughput upper limit value setting program executed by the storage management device outputs, to the storage device, a command for switching the throughput upper limit value from the upper limit value 1 to upper limit value 2, such that the throughput upper limit value is switched.
