摘要： In a path determination unit of a SAS expander connected to a SAS initiator and connected via first and second paths to a SAS target, an SSP controller receives an SSP command frame received from the SAS initiator; a requested-data-length manager stores a requested data length of the SSP command frame in a requested-data-length storage unit; and a data-transfer-amount manager selects one of the first and second paths having a smaller one of the data transfer amounts stored in a data-transfer-amount storage unit, and adds the requested data length to the data transfer amount of the selected path. The SSP command frame is transmitted to the SAS target via the selected path. Upon receipt of an SSP response frame responding thereto, the requested data length is deleted from the requested-data-length storage unit, and the requested data length is subtracted from the data transfer amount of the selected path.

摘要： Embodiments are disclosed for a method for a tape library in hierarchical storage. The method includes receiving a recall request for a recall file having two copies stored in two tape libraries that are performing two migrations of two sets of files. The method also includes determining two migration progress values corresponding to the two migrations. Additionally, the method includes assigning the recall request to one of the two tape libraries having a greater value of the two migration progress values.

摘要： A computer-implemented method can include obtaining tape data for one or more tapes. The tape data can include pointer data corresponding to a first file. The method can further include determining, based on the tape data, that the first file is stored on a first tape of the one or more tapes. The first tape can have an export status. The method can further include determining that the pointer data includes a pointer to the first tape and a pointer to a second tape. The second tape can have a non-export status. The method can further include storing at least a portion of the tape data. The method can further include initiating, based on the first tape having the export status, a deactivation of the pointer to the first tape.

摘要： The method includes identifying, by one or more computer processors, a live file. The method further includes identifying, by one or more computer processors, a snapshot that corresponds to the live file. The method further includes amending, by one or more computer processors, data corresponding to the identified live file to include tracking data for the identified snapshot. The method further includes amending, by one or more computer processors, data corresponding to the identified snapshot of the live file to include tracking data for the identified live file. The method further includes determining, by one or more computer processors, a difference in the data between the identified live file and the identified snapshot. The method further includes amending, by one or more computer processors, the identified snapshot to include only the determined difference in data between the identified live file and the identified snapshot.

摘要： A system and method for preventing inefficient recalls in a hierarchical storage management (HSM) system are presented. Difference data may be received for updating a target file stored in a first storage system having at least an upper storage layer and a lower tape layer. The difference data may be stored in a stub file located on the upper storage layer and corresponding to the target file in the first storage system located on the lower tape layer. A recall operation may be executed that copies the target file from the lower tape layer to the upper storage layer. The difference data stored in the stub file may be copied to the target file copied onto the upper storage layer from the lower tape layer according to one or more predetermined events.

摘要： An approach, for storing video data in a plurality of tape media via a ring buffer. A tape data splitter receives video data stored in a ring buffer. The tape data splitter writes the video data to a current tape media. The tape data splitter detects an end of tape media event. The tape data splitter responds to the end of tape media event, by switching the current tape media to a next tape media. The tape data splitter selects a resume point for the video data stored in the ring buffer and writes to the next tape media, the video data stored in the ring buffer that is subsequent to the resume point.

摘要： In a hierarchical storage management system (HSM), a scheduled-recall request is associated with a start-time. Prior to the scheduled-recall request start-time, if a first recall request is directed to the same storage medium as is the scheduled-recall request, the method performs some or all of the scheduled-recall request, with low priority processing, during times that the storage drive (performing the first recall request) is otherwise idle. After the scheduled-recall request start-time, the priority of the scheduled-recall request is increased and data targeted by the scheduled-recall request, that had not already been recalled during the low priority processing, are subsequently processed with high priority.

摘要： In an approach to encryption key management, a computing device, responsive to a key storage condition, stores, in a cache memory, a first e/d key. The computing device receives a request to read a first file. The computing device, responsive to the request, accesses the first file, with the accessing of the first file including: accessing, from the cache memory, the first e/d key, decrypting the first file using the first e/d key and a second e/d key, and accessing the decrypted version of the first file.

摘要： An apparatus, method, system, and program product are disclosed for data replication. One method includes determining a predicted match ratio. The predicted match ratio may predict a percentage of a current version of a file that matches a prior version of the file. The method may include performing a delta transfer if the predicted match ratio is greater than a predetermined threshold. The delta transfer may transfer a portion of the current version of the file that has changed relative to the prior version of the file. The method may include performing a transfer of the current version of the file if the predicted match ratio is less than the predetermined threshold.

摘要： In a hierarchical storage memory (HSM), a file recalled by a specific application is migrated as soon as possible after completion of the application process. Specifically, the effective UID of a specific process is preregistered on an HSM client. After a recall operation is performed on a certain file from the user ID, when there is no access from the UID to the file for a given length of time, the file is migrated. This prevents files premigrated by access from any application other than the specific one from being handled in the same way, resolving a disadvantageous problem caused when these (premigrated) files are not desired to be migrated preferentially.
