摘要： A multi-node storage system includes a plurality of nodes each configuring a node group having a hardware control unit that includes one or more drivers of a resource group of the node and a command control unit that, where the node receives an I/O (Input/Output) command, controls the hardware control unit in an I/O process in accordance with the I/O command. At least one node includes an allocation decision unit. The allocation decision unit decides resource allocation to the hardware control unit and the command control unit for one or more nodes on the basis of the I/O characteristics of the one or more nodes including the node. Of the resource quantity of the resource group of the node, a resource quantity allocated to each of the hardware control unit and the command control unit complies with the decided resource allocation in each of the one or more nodes.

摘要： To detect an abnormality of logical and physical addresses, a storage device includes: plural drives each having a storage medium configuring a logical volume provided to a host device; a front end I/F that receives an I/O request including a logical address for identifying a logical storage area of the logical volume, and user data from the host computer; a processor that controls conversion from the logical address into the physical address for identifying a physical storage area of the storage medium; and a back end I/F that controls write/read of user data with respect to the drives based on the physical address. In the drives, data where a first guarantee code obtained based on the physical address and the logical address corresponding to the physical address is added to the user data is stored in the physical storage area designated by the physical address of the storage medium.

摘要： Regardless of which of the multiple storage subsystems provided with the same identification information is accessed from a plurality of host computers, multiple volumes provided with the same identification information among the storage subsystems are subjected to extent exclusion sharing. Therefore, a multiplex volume provided with the same identification information among the plurality of storage subsystems and a first storage subsystem for processing input/output requests by the channel command to the multiplex volume are provided, wherein if the channel command received from the host computer or via a control unit of a second storage subsystem is an input/output request of the multiplex volume, a control unit of the first storage subsystem determines the access authority regarding an extent range of the multiplex volume designated by the channel command, based on information on whether an input/output processing regarding the extent range is already executed based on another request.

摘要： The computer system includes a node including a processor and a memory, and the processor and the memory serve as arithmetic operation resources. The computer system has an application program that operates using the arithmetic operation resources, and a storage controlling program that operates using the arithmetic operation resources for processing data to be inputted to and outputted from a storage device by the application program. The computer system has use resource amount information that associates operation states of the application program and the arithmetic operation resources that are to be used by the application program and the storage controlling program. The computer system changes allocation of the arithmetic operation resources to the application program and the storage controlling program used by the application program on the basis of an operation state of the application program and the use resource amount information.

摘要： A storage system includes: a storage device including a recording medium that stores data and a device controller that executes addition processing involving a change of state of the data with respect to the data; and a storage controller that controls input and output of data for the storage device. The storage controller transmits, to the storage device, determination information that can be utilized by the device controller for determining whether or not to execute the addition processing along with input-output processing relating to input-output target data. The device controller controls execution of the addition processing with respect to the input-output target data based on the determination information transmitted from the storage controller.

摘要： Improvement of read/write access performance with respect to a disk is proposed. A controller manages a first volume format LDEV, in which each distributed user data area and each distributed information area among a plurality of the distributed user data areas for storing a data part and a plurality of the distributed control information area for storing a control information part, are targets that capacity is changed. The controller also manages a second format LDEV, which include a plurality of groups each of which is formed from one distributed user data area and one distributed control information area, and in which each group is a unit that capacity is expanded in a real storage area. The controller converts a data address of the data part belonging to the first volume format LDEV into a data address of a data part of the second volume format LDEV in order to execute input/output processing with respect to the data part, when received an request for access to the data part belonging to the first volume format LDEV.
