摘要： An allocation control apparatus allocates duplicate logical volume divided areas to virtual storage areas that do not have data storage area in the physical storage area. The apparatus associates identification information of the allocated virtual storage areas, of the duplicate logical volume divided areas, and of duplication source logical volume divided areas to be set in the management information. The apparatus detects, upon a data writing request, based on the management information, the unallocated real storage area in the logical volume divided area. The apparatus reallocates the real storage area to the duplicate logical volume divided area to update the management information. The apparatus identifies, based on the management information, the real storage area allocated to the duplication source logical volume divided area corresponding to the duplicate logical volume divided area. The apparatus copies data stored in the real storage area to the real storage area.

摘要： According to an aspect of the embodiment, a packet analyzing apparatus monitors a concentration level of input and output access from an access apparatus to a disk device, specifies a data area to which the concentration level of input and output access exceeds a first threshold, and instructs a storage server to cache the data area. The packet analyzing apparatus monitors a concentration level of input and output access to a data area to which the data area is cached, and, when the concentration level of input and output access is below a second threshold, instructs the storage server to release the caching.

摘要： A simultaneous failure occurrence degree calculation section calculates a simultaneous failure occurrence degree a value of which becomes smaller with an increase in a difference between numeric values indicative of manufacture date information on a computer which performs a process on the basis of a duplication combination management program. A combination pattern generation section then combines two of a plurality of storage apparatus and generates a plurality of combination patterns. A simultaneous failure occurrence degree adding section then calculates a total of simultaneous failure occurrence degrees corresponding to combinations of storage apparatus for each of the plurality of combination patterns. A duplication combination pattern determination section then determines that a combination pattern for which the total of simultaneous failure occurrence degrees is the smallest is a duplication combination pattern.

摘要： A data allocation control program manages data allocation when data is distributively stored in a plurality of disk nodes that are shifted to a power saving mode unless access is performed for a certain time. The program produces a plurality of allocation pattern candidates each indicating the disk nodes in which the respective data are to be stored. The program calculates a no-access period expectation that represents an expected value of occurrence of a no-access period during which access is not performed to some of the disk nodes. The program selects as an allocation pattern for data reallocation, one of the plurality of produced allocation pattern candidates with the largest calculated no-access period expectation. The program instructs the disk nodes to reallocate the respective data in accordance with the selected allocation pattern.

摘要： A storage control apparatus monitors whether or not one or more storage management apparatuses are properly operating. A recovery target extraction unit extracts a recovery target storage area when the existence of a malfunctioning storage management apparatus is detected, the recovery target storage area being a storage area that has been duplexed with a storage area of the malfunctioning storage management apparatus. A duplexing control unit performs control so that, if the recovery target storage area has no data stored therein, the recovery target storage area is duplexed with a storage area that has no data stored therein and that is unused. If the recovery target storage area has data stored therein, the recovery target storage area is duplexed with a non-duplexed storage area and the data stored in the recovery target storage area is copied into the non-duplexed storage area.

摘要： A wireless communication apparatus includes an RF front-end unit constituting reception and transmission systems, a digital baseband signal processor, and a bias current circuit. The digital baseband signal processor performs a process of a digital baseband receive signal received from a reception system and performs a process of a digital baseband transmit signal supplied to a transmission system. The bias current circuit supplies a reference current to at least a part of a circuit constituting the reception system within the RF front-end unit. The bias current circuit switches the reference current supplied to at least the part of the circuit constituting the reception system within the RF front-end unit, in response to a transmission-operation control signal outputted by the digital baseband signal processor to the transmission system within the RF front-end unit.

摘要： A storage management process and a storage management apparatus for managing first data stored in a storage area in a storage device in a first one of storage nodes constituting a distributed storage system. The first data is read out from the storage device and checked for normality in response to a request. When the first data is abnormal, a second one of the storage nodes paired with the first one is determined by reference to management information which is stored in advance, and second data which is identical to the first data and managed by the second one of the storage nodes is acquired. Then, the storage area is overwritten with the acquired second data when the first data is abnormal.

摘要： An interchangeable lens is disclosed which prevents the camera body and interchangeable lens from being damaged even if an attempt is made to erroneously mount therebetween. The interchangeable lens is a second interchangeable lens whose flange back is the same as that of a first interchangeable lens and includes a protruding portion protruding from a mount reference surface. The protruding amount of the protruding portion is set when the second interchangeable lens has a specific phase relationship with a first camera, so that the protruding portion contacts a first wall portion of the first camera, and is set when the second interchangeable lens has a phase relationship with the first camera other than the specific phase relationship and a bayonet lug of the second interchangeable lens contacts a bayonet lug of the first camera, so that the protruding portion is away from the first wall portion.
