摘要： A method begins with a processing module of a dispersed storage network (DSN) maintaining, over time, a continuum of time-to-repair information regarding a plurality of storage units of the DSN and maintaining, over time, a continuum of time-to-failure information regarding the plurality of storage units. When the continuum of time-to-repair information and the continuum of time-to-failure information are each below undesired levels, the method continues with the processing module changing dispersed storage error encoding parameters of a logical storage vault of the DSN by lowering a decode threshold number with respect to a current decode threshold number and increasing a pillar width number with respect to a current pillar width number. The method continues with the processing module re-encoding stored encoded data of the logical storage vault based on the increased pillar width number and the decreased decode threshold number.

摘要： A method, system, and/or computer program product log at least one stream of records in a data-processing system. A stream of records is received in succession. Records from the stream of records are logged into a log structure. In response to fulfillment of a pre-defined purging condition: the logging of the records are diverted to a buffer structure; the log structure is purged according to a set of purging criteria in response to the diverting; the records logged in the buffer structure are moved to the log structure in response to a completion of the purging; and the logging to the log structure is restored in response to a completion of the moving.

摘要： A first control apparatus transmits, to a second control apparatus, a first error score based on an error detection situation at the time of accessing a first memory device through the second control apparatus, and transmits, to a third control apparatus, a second error score based on an error detection situation at the time of accessing a second memory device through the third control apparatus. The second control apparatus determines whether the first memory device malfunctions, based on a sum of a third error score based on the error detection situation at the time of accessing the first memory device and the received first error score. The third control apparatus determines whether the second memory device malfunctions, based on a sum of a fourth error score based on the error detection situation at the time of accessing the second memory device and the received second error score.

摘要： A mechanism is provided in a data processing system for data replication. The mechanism divides a set of data to be replicated into a plurality of slices. Each slice of the plurality of slices is to be copied from a primary site to a master secondary site within a plurality of secondary sites. The plurality of secondary sites comprises the master secondary site and at least one subsidiary peer site. The mechanism copies the plurality of slices from the primary site to the plurality of secondary sites such that the master secondary site stores a first slice of the set of data and each of the at least one subsidiary peer site stores a corresponding slice of the set of data. Responsive to completion of copying the plurality of slices to the plurality of secondary sites, for each of the at least one subsidiary peer site, the mechanism initiates copying of the corresponding slice of the set of data to the master secondary site.

摘要： A method includes, in a memory controller that controls a memory, evaluating an available memory space remaining in the memory to write data. A redundant storage configuration is selected in the memory controller depending on the available memory space. Redundancy information is calculated over the data using the selected redundant storage configuration. The data and the redundancy information are written to the available memory space in the memory.

摘要： A method for processing a data object access request in a storage system having storage devices can include receiving an access request for accessing a first data object, the request being received by a controller that stores at least two consecutive data objects received by the storage system in different storage devices. The method may then include detecting that the first data object is corrupted, and determining, in response to the detecting, that a second data object has identical data as the first data object. Determining that the second data object has identical information as the first data object can include determining that a first metadata tag corresponding with the first data object and a second metadata tag corresponding with the second data object are identical. The second data object can then be provided in a response to the access request.

摘要： An information processing system includes a storage unit storing application identification information of an application for executing a first process in association with information relating to the first process; a receiving unit that receives a request including the application identification information and information relating to electronic data from a device; a process execution unit that executes the first process on electronic data based on the information relating to the first process stored in association with the application identification information included in the request and the information relating to the electronic data included in the request; and a process generation unit that generates information relating to a second process for rolling back a processing result of the first process executed by the process execution unit. The process execution unit executes the second process based on the generated information relating to the second process when an error occurs in the first process.
