Patent number: 8307178Abstract: A copy source storage controller received write data added with a time and issued from a host computer transfers the write data with the time to a copy destination storage controller. If there are a plurality of copy destination storage controllers, a representative copy destination storage controller compares times of write data copied to the plurality of copy destination storage controllers, and writes the write data in copy destination logical volumes in the sequential order of time. The representative copy destination storage controller judges that integrity of the write data is established, if a communication procedure is established with the copy destination storage controller and if the statuses of the copy source/destination logical volumes are coincident. In remote copy which guarantees integrity of write data and traverses a plurality of storage controllers, it is possible to judge at an optional time point whether integrity of write data can be guaranteed.Type: GrantFiled: August 15, 2011Date of Patent: November 6, 2012Assignee: Hitachi, Ltd.Inventors: Nobuhiro Maki, Yuri Hiraiwa, Yoshiyuki Nishi, Katsuhisa Miyata, Akira Deguchi

Patent number: 8255649Abstract: The present invention causes an asynchronous remote copy to work together with storage clustering technology. A host computer program for controlling the asynchronous remote copy carries out an asynchronous remote copy pair operation by asynchronously working together with a switchover instruction of a storage clustering control program that performs a host write-destination volume switchover in a storage clustering environment.Type: GrantFiled: January 14, 2010Date of Patent: August 28, 2012Assignee: Hitachi, Ltd.Inventors: Yuri Hiraiwa, Yoshiyuki Nishi, Kenichi Oyamada, Yoshinori Matsui

Publication number: 20110161609Abstract: Proposed is an information processing apparatus and its control method capable of acquiring the operation results of the same point in time in a plurality of storage apparatuses in a highly reliable manner. With this information processing apparatus connected to a plurality of storage apparatuses and its control method, a time difference between an internal time of the storage apparatus and an internal time of the information processing apparatus is detected regarding each of the plurality of storage apparatuses, a time added with the time difference between the internal time of the storage apparatus and the internal time of the information processing apparatus as an execution time of a predetermined operation is set to the plurality of storage apparatuses at an arbitrary future time, and an execution result of the predetermined operation is collected from each of the plurality of storage apparatuses after the lapse of the future time.Type: ApplicationFiled: March 2, 2010Publication date: June 30, 2011Inventors: Kenichi OYAMADA, Yoshiyuki NISHI

Patent number: 7827367Abstract: A controller sets a specified time which is a time that specifies a time in the future relative to the current time for all of one or more secondary storage systems. The respective secondary storage systems have a logical volume for backup (BVOL), and set a backup preparation end state when a journal up to a specified time has been established, and report information showing a preparation end state to the controller. The controller issues a backup command to all of the one or more secondary storage systems when information showing a preparation end state is reported from all of the one or more secondary storage systems.Type: GrantFiled: January 8, 2008Date of Patent: November 2, 2010Assignee: Hitachi, Ltd.Inventors: Takeyuki Imazu, Yuri Hiraiwa, Nobuhiro Maki, Yoshiyuki Nishi, Kazuhiko Watanabe

Patent number: 7774567Abstract: In a copy control method, during a process for the acquisition of a data copy at a designated time, a recovery period of time can still be reduced when an input/output request is issued for copy source data at the designated time. For a system that includes a first storage device in which data are stored, a second storage device that obtains a data copy, and a host computer that writes data to the first storage device, the second storage device obtains blank input/output requests that are issued at predetermined time intervals if the host computer does not generate an input/output request for the first storage device, and the second storage device determines that a time closest to a predetermined data copy acquisition time, which is a target time for the acquisition of a data copy, is a copy execution time for the acquisition of a data copy.Type: GrantFiled: January 29, 2007Date of Patent: August 10, 2010Assignee: Hitachi, Ltd.Inventors: Yoshiyuki Nishi, Nobuhiro Maki, Kenichi Oyamada, Kazuhiko Watanabe, Hiroshi Yamamoto

Patent number: 4068339Abstract: A flexible matting for use at an entrance porch, corridor, veranda, pool-side, interior floor of automobiles, etc. This matting consists of a base on which tread bars and rows of ridges bearing piles are arranged in a definite direction with appropriate spacings between them so that the mud adhered to shoes can be removed by the piles and collected in the grooves formed between the ridges. Thus, the removal of mud from the present matting is very easy as compared with a conventional one.Type: GrantFiled: December 4, 1975Date of Patent: January 17, 1978Assignee: Sumitomo Bakelite Company LimitedInventors: Kenjiro Maruyama, Tsuyoshi Miki, Yoshiyuki Nishi, Masato Takao
