  • Patent number: 10969985
    Abstract: In a case of exchanging a migration source storage controller and a migration destination storage controller sharing one storage medium during replacement of storage devices, when hardware configurations or data management forms of the storage controllers are different, data in the storage medium cannot be shared even when data management information can be copied. Accordingly, a storage system, having a storage control unit and a storage drive provided with a storage medium, includes data management information for accessing data in the storage drive. A first storage control unit copies data management information about the data in the storage drive to a second storage control unit. When a write request is received from a host after copying of the data management information begins, each of the first storage and second storage control units stores write data related to the write request in a separate storage area of the storage drive.

  • Patent number: 10908834
    Abstract: In some examples, a load on a first node of a plurality of nodes, over a period of time, may be determined based at least in part on comparing a load parameter with a load threshold. When the load parameter exceeds the load threshold, one or more nodes may be randomly selected from the plurality of nodes. Furthermore, an access load to move from the first node may be determined. The access load may correspond at least partially to data access requests received from user computing devices over the period of time. In addition, at least one node from the randomly selected one or more nodes may be determined that is able to receive the access load. A portion of data may be transferred from the first node to the at least one node. For instance, the portion of data transferred may be based on the access load.

  • Patent number: 10884924
    Abstract: 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.
