20090171473 | STORAGE SYSTEM, STORAGE SYSTEM CONTROL METHOD AND STORAGE SYSTEM CONTROL APPARATUS - A storage system includes a housing, a cooling unit cooling the interior of the housing, and a plurality of control units adapted to control the cooling unit. The control units each include a mount state acquisition unit acquiring a mount state of the control unit in the housing, an operation state acquisition unit acquiring an operation state of the cooling unit, and a determining unit determining a provisional main control unit, from among the plurality of control units, that is operable to control the entire cooling unit based on information acquired from the mount state acquisition unit and the operation state acquisition unit. | 07-02-2009 |
20090198931 | INFORMATION PROCESSING APPARATUS AND DATA BACKUP METHOD - An information processing apparatus includes a battery for providing the interior of the information processing apparatus with power; a volatile memory for storing data; a nonvolatile memory for backupping the data stored in the volatile memory; a controller for controlling backup of the data in accordance with a process comprising the steps of: saving the data into the nonvolatile memory; upon recovery of the power from the external power source, writing back the data into the volatile memory; and deleting the data saved in the nonvolatile memory; wherein when the power from an external power source to the information processing apparatus is stopped during deleting data in the nonvolatile memory, the controller selectively writes back deleted data from the volatile memory into the nonvolatile memory. | 08-06-2009 |
20100318844 | BACKUP METHOD AND DISK ARRAY APPARATUS - A backup method makes a backup of cache data to a nonvolatile memory by using a controller, the cache data being stored in the volatile memory. The backup method includes writing the cache data stored in the volatility memory in a selected area of the nonvolatile memory, generating party data by operating the parity operations between each of the predetermined parts of the cache data in the volatile memory, verifying whether an error found in the part of the cache data in the nonvolatile memory can be recovered by using the parity data, and rewriting the part of the cache data when the error found in the part of the cache data in the nonvolatile memory cannot be recovered by using the parity data in an area of the nonvolatile memory different from the selected area. | 12-16-2010 |
20130283069 | STORAGE APPARATUS, CONTROL APPARATUS AND CONTROL METHOD - A storage apparatus that includes a power supply unit that supplies power to a controller when power supply from the outside to a storage apparatus stops, a surplus power determination unit that determines surplus power that is power, which is to be supplied by the power supply unit and by which power for the saving of data into a nonvolatile memory is exceeded, a target voltage determination unit that determines a first target voltage based on the surplus power, and a charging processing unit that carries out a charging process for the power supply unit with a first current value until the first target voltage reached and that carries out a charging process for the power supply unit with a second current value lower than the first current value until a second target voltage higher than the first target voltage is reached from the first target voltage. | 10-24-2013 |
