  • Publication number: 20190095132
    Abstract: In a case where updated data using a first logical address as a write destination and existing data using a second logical address as a write destination duplicate with each other, a computer system writes predetermined data instead of updated data to a memory segment associated with a first physical address, and dynamically maps the first logical address to a second physical address. The computer system transmits a write command of the predetermined data or an unmapping command that designates a virtual address that complies with the first physical address, to a storage device that corresponds to the first physical address. The first and second logical addresses are logical addresses that belong to a logical address range which is at least a part of a logical address space. The first physical address is a physical address that belongs to a physical address range which is at least a part of a physical address space, and is a physical address statically mapped to the first logical address.

  • Publication number: 20180301122
    Abstract: A display control apparatus configured to be connected to an imaging apparatus is provided. The display control apparatus includes an obtaining unit configured to obtain image data captured by the imaging apparatus by capturing an image behind a vehicle; an edge image generation unit configured to generate edge image data that clearly indicates a peripheral portion of the image data to be viewed via an electric mirror that is placed at a rear-view mirror position inside the vehicle; a display image generation unit configured to generate display image data by superimposing the generated edge image data onto the obtained image data; and a control unit configured to control the generated display image data to be viewed via the electric mirror.

  • Patent number: 9977813
    Abstract: As a method for migrating data of a volume adopting a snapshot function to a new storage system, in order to perform migration without depending on a method for compressing snapshot data of a migration source storage system, and without stopping transmission and reception of data between the host computer and the storage system, at first, after migrating data of a volume being the source of snapshot (PVOL), migration is performed sequentially from newer generations. At this time, migration target data of each SVOL is all the data within the migration source storage system. The SVOL data copied to a migration destination storage is compared with one-generation-newer SVOL data within the migration destination storage system, and based on the comparison result, a difference management information is created. If there is difference, a VOL allocation management table is updated, and difference data is stored in the area allocated within the pool.

  • Publication number: 20180052772
    Abstract: The storage system includes a first partition which is associated with a first processor and in which the first processor temporarily stores data relating to I/O requests processed by the first processor; and a second partition which is associated with a second processor and in which the second processor temporarily stores data relating to I/O requests processed by the second processor. Each processor independently controls the size of the first partition of the first cache memory and the size of the first partition of the second cache memory, and also independently controls the size of the second partition of the first cache memory and the size of the second partition of the second cache memory.

  • Publication number: 20180032433
    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.

  • Publication number: 20170356066
    Abstract: The present invention is intended for effectively removing copper, iron, sulfur, which are impurities, from activated carbon on which gold is adsorbed before gold eluting in the point of view of gold recovery, and is related to a method for eluting gold from an activated carbon on which at least sulfur (S) and gold (Au) are adsorbed, whereas the activated carbon is washed with an alkali solution before eluting the gold, and then the gold is eluted from the activated carbon.

  • Publication number: 20130282998
    Abstract: A backup system and backup method with which the processing time can be shortened without increasing the overhead and burden on the system administrator in a two-stage backup. In a backup system which executes a two-stage backup, the storage apparatus searches for a secondary volume which can be paired with a primary volume on the basis of the pair create instruction, determines whether the volume size of the secondary volume obtained as a search result is greater than the volume size of the primary volume and, if the volume size of the secondary volume is greater than the volume size of the primary volume, sets the volume size of the secondary volume as the same size as the volume size of the primary volume without changing the substantial volume size of the secondary volume, and notifies the host of information on the set volume size of the secondary volume and information indicating that a pair has been created.
