    摘要: An electrolysis of sodium chloride is carried out by using a cation exchange membrane obtained by the following treatment.The cation exchange membrane is prepared by treating one surface of a membrane of a perfluorocarbon polymer having sulfonyl halide groups with a diamine or a polyamine at a temperature of 170.degree. C. to a deterioration temperature of the membrane and immersing a diene derivative having a carboxyl group or a group which can be converted to carboxyl group into the membrane to polymerize the diene derivative and treating the membrane with a water miscible organic solvent having a boiling point of higher than 120.degree. C. in 760 mmHg between smooth plates at 80.degree. C. to 180.degree. C.

    摘要: A method for verifying data in a storage system is disclosed. A host computer transmits area management data to a storage controller. The area management data specifies a range of a storage area in a storage device to be used by an application program having a mechanism for verifying data suitability. Upon receipt of an input/output request transmitted from the host computer, the storage controller performs verification, which is usually performed by the application program, of the data that is to be processed according to the data input/output request and to be input/output to/from the storage area, which is specified in accordance with the received area management data.

    摘要: A method for managing data stored in a hierarchical storage unit of a storage apparatus is disclosed. The storage unit includes a first storage medium having a first access speed and a second storage medium having a second access speed. The first access speed is different from the second access speed. The method comprises determining a first access frequency for information of first type, the first access frequency being associated with a first period of past time. A second access frequency of the information of first type is determined. The second access frequency is associated with a second period of past time and is different than the first access frequency. At least a portion of the information of first type is transferred from the first storage medium to the second storage medium prior to a second period based on the second access frequency determined in the determining-a-second-access-frequency step, the second period corresponding to the second period of past time.

    摘要: The present invention provides a storage system and a method of controlling the storage system, in which a second site rapidly resumes system process when a first site is damaged. The storage system comprises a first site including a first storage device, a second site including a second storage device, and a third site including a third storage device, and the method of controlling the storage system comprises a step of making a logical volume of the second storage device consistent with a logical volume of the first storage device by remotely copying only the differential data between the logical volume of the first storage device and the logical volume of the second storage device from a logical volume of the third storage device to the logical volume of the second storage device when the first site is damaged.

    摘要: When plural copy groups including pairs exist, remote copying for pairs belonging to copy groups is suspended selectively on a copy group-to-copy group basis, instead of suspending remote copying in all the copy groups at once. A computer system has a host computer, plural first storage systems comprising plural first logical disks, and plural second storage systems comprising plural second logical disks. A first logical disk and a second logical disk paired with the first logical disk, and each pair belongs to either a first copy group or a second copy group. To selectively suspend remote copying on a copy group-to-copy group basis, one of the copy groups is specified first and then pairs belonging to this copy group are designated. The first storage systems comprising first logical disks of the designated pairs suspend remote copy processing for the designated pairs.

    摘要: A disk storage system has a control unit having a plurality of external ports connectable to a mirrored disk including two disks to which write data is written. When the control unit receives two read requests issued from a processor to the disk unit group, a first read operation is performed to read data requested by the first read request from one of the disks and a second read operation is performed to read data requested by the second read request from the other one of the disks. Also, a first transferring operation is performed to transfer data read by the first read operation to one external port of the control unit and a second transferring operation is performed to transfer data read by the second read operation to another external port of the control unit. Further, the data read by the two read operations is transferred to the processor via the external ports.
