    摘要： There is a journal area and one or more logical volumes comprising a first logical volume. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any storage area of a plurality of storage areas configuring a logical volume, or a data element that is written to the storage area. A controller has a size receiver that receives a write unit size, which is the size of a write data element received from a computer, and a size setting unit that sets the received write unit size in a memory for one or more logical volumes. The size of a journal data element stored in a journal area based on the set write unit size is the write unit size.

    摘要： A first storage system is connected to a second storage system, and an external device within the first storage system is provided to a host as a device of the second storage system. The second storage system includes a cache control section having cache adaptors, each controlling a disk and a cache, a protocol conversion section including protocol adaptors that switch requests from the host to appropriate ones of the cache adaptors, a management adaptor, and an internal network that mutually connects the cache adaptors, the protocol adaptors and the management adaptor. The first storage system being connected to any of the protocol adaptors is connected to the second storage system. The second storage system executes a processing for the external device by the cache control section, or connects to the first storage system through the protocol conversion section without the cache control section executing processing for the external device.

    摘要： An intermediate value derived from old and new data record values or old and new data themselves are sent from a control unit to a disk unit which stores a parity record as information necessary for updating parity. The disk unit reads an old parity record and generates a new value of parity record based on the read old parity and the information received from the control unit. The generated new value is stored in an empty record on the storage medium to which a read/write head is first positioned after the generation of the new value and in which effective data has not been stored. In a disk array system, a time required to update the parity record due to the updating of the data record is reduced and a performance of the storage unit subsystem is improved.

    摘要： A first storage system comprises a first logical volume, and a first controller that has a first memory. A second storage system comprises a second physical storage device that constitutes the basis of a second logical volume and a journal area, and a second controller that has a second memory. At least the first memory stores a write unit size, which is the size of a write data element. The journal area is a storage area in which is stored a journal data element, which is a data element that is stored in any block of a plurality of blocks configuring the first and/or second logical volume, or a data element that is written to this block. The size of the journal data element, and the size of the respective blocks that are managed as the respective components of the first and second logical volumes are the write unit size.
