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： A method for application migrating from a first cluster to a second cluster. The method may include detecting application migration request from the first cluster to the second cluster for performing application migration; identifying first volumes associated with the first cluster that are used by the application; establishing data copying from the first volumes of a first storage device associated with the first cluster to second volumes of a second storage device associated with the second cluster; determining if a copy condition is met based on the data copying; for meeting the copy condition, stopping the application on the first cluster; flushing uncopied data from the first volumes to the second volumes; determining whether the flushing of the uncopied data is completed; and for the flushing of the uncopied data being completed, deploying the application on the second cluster.

摘要： 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.

摘要： The present invention is directed to realize a QoS function in the unit of a virtual volume group existing over a plurality of storage apparatuses. A management system of a storage system forms a virtual volume group by using a plurality of volumes provided by a plurality of storage apparatuses. In the virtual volume group, a QoS setting value including a data input/output amount is set. IO processing ability provided from each of the volumes to the virtual volume group is set so as to satisfy the QoS setting value. The management system sets the IC processing ability provided from each of the volumes to the virtual volume group on the basis of operation information of each of the volumes.

摘要： The computer system executes a storage program that operates on an OS to provide a logical volume to a host. The computer system includes volume management information including information on a storage function to be applied to the logical volume provided by the storage program. Upon receiving an I/O request for the logical volume from the host, the OS determines whether it is necessary for the storage program to perform an I/O process on the basis of the information on the storage function to be applied to the logical volume by referring to the volume management information. When it is determined that the I/O process is necessary, the OS communicates with the storage program and the storage program executes the I/O process. When it is determined that it is not necessary for the storage program to perform the I/O process, the OS outputs an I/O response to the host.

摘要： A storage system receives a write request which specifies a logical volume address associated with a RAID group, and makes a first determination whether write target data in accordance with the write request exists in a cache memory. When the first determination result is negative, the storage system makes a second determination whether at least one of one or more conditions is met, the condition being that random write throughput performance is expected to increase by asynchronous de-staging processing of storing the write target data in the RAID group asynchronously to write processing performed in response to the write request. When the second determination result is negative, the storage system selects, for the write request, synchronous storage processing, which is processing of storing the write target data in the RAID group in the write processing and for which a load on a processor is lower than the asynchronous de-staging processing.

摘要： 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.

摘要： By assigning a physically continuous memory area to a virtual storage apparatus operated on an OS, the performance of the virtual storage apparatus is secured. A processor operates an OS, and the processor executes a plurality of processes on the OS. The plurality of processes includes a first virtual storage apparatus. The first virtual storage apparatus executes an I/O process, and includes a cache for storing data that is subjected to the I/O process. The processor assigns a resource in a computer to the plurality of processes, and the processor creates area information that indicates physical addresses assigned to the processes in a memory. On the basis of the area information, the processor selects a continuous area, which is a physically continuous area from the memory and assigns the continuous area to the cache.
