Abstract: 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.

Abstract: 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.

Abstract: Provided is a resource allocation determination method for a VM/container, volume, and the like created as a new VM/container or volume without exceeding an upper limit of a computer resource of a node in an HCI environment. In order to determine allocation of at least one of a virtual machine, a container, and a volume in a system of the HCI environment, a use state of a computer resource shared by a virtual machine and a storage controller operating on each node is managed, and an allocation destination node of the new virtual machine, container, or volume is determined based on the use state without exceeding an upper limit of a computer resource of the allocation destination node.

Abstract: According to one embodiment, a storage system includes a representative node and a plurality of general nodes including a plurality of resources. Each of the general nodes stores resource status information indicating respective statuses of the plurality of resources in a first storage unit thereof. The representative node stores resource status information collected from the plurality of general nodes in a second storage unit thereof, decides whether to acquire the resource status information from the first storage unit of the general node or to acquire the resource status information from the second storage unit based on a received request, and transmits the resource status information acquired from a decided acquisition destination to an issuing source of the request.

Abstract: 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.

Abstract: The computer system includes a management unit that holds a service template in which a service provided by the host is described, and a necessary resource table in which a resource amount necessary for the node is described so as to execute the service with a predetermined parameter. The management unit receives input of the service template and the parameter, calculates a necessary resource amount based on a combination of the input service template and parameter with reference to the necessary resource table, selects a node that satisfies a condition for the calculated necessary resource amount, executes a service for the service template, and updates the necessary resource table based on a change in a load of the resource before and during the service is executed.
