20080263271 | System for Selectively Performing a Secure Data Erase to Ensure Timely Erasure - A system is provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased. | 10-23-2008 |
20080263274 | System for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process - A system is provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance. | 10-23-2008 |
20080263293 | Method for Selectively Performing a Secure Data Erase to Ensure Timely Erasure - A method and computer program product are provided to ensure a timely secure data erase by determining an erasure deadline for each physical volume of a plurality of physical volumes and calculating a remaining time for each physical volume. The remaining time is calculated for each physical volume by comparing a current date to the erasure deadline of each physical volume respectively. The physical volumes may then be sorted based on the remaining time and the physical volume with a shortest calculated remaining time will be selectively secure data erased. | 10-23-2008 |
20080263294 | Method for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process - A method and computer program product are provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance. | 10-23-2008 |
20110225356 | Method for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process - A method and computer program product are provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance. | 09-15-2011 |
20110225357 | System for Determining Allocation of Tape Drive Resources for a Secure Data Erase Process - A system is provided to ensure a timely secure data erase by determining whether allocating an additional tape drive would improve secure data erase performance by evaluating a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average time to an erasure deadline and a minimum expiration threshold. An additional tape drive is allocated for the secure data erase process when it is determined that allocating an additional tape drive would improve secure data erase performance. | 09-15-2011 |
20110289347 | RECOVERY FROM MEDIUM ERROR ON TAPE ON WHICH DATA AND METADATA ARE TO BE STORED BY USING MEDIUM TO MEDIUM DATA COPY - A copy export application implemented in a computational device receives a request to perform a copy export operation of data and metadata to a selected tape in a tape library coupled to the computational device. The copy export application copies the data from the computational device to the selected tape. The copy export application determines a medium error on the selected tape while copying the metadata from the computational device to the selected tape, subsequent to completion of the copying of the data from the computational device to the selected tape. The copy export application sends a request to a tape control application to replace the selected tape by a new tape and copy the data from the selected tape to the new tape. The copy export application copies the metadata to the new tape. | 11-24-2011 |
20120311253 | Reallocation of Tape Drive Resources Associated With a Secure Data Erase Process - A method according to one embodiment includes determining whether to reallocate one or more of a plurality of tape drives that are presently allocated for a secure data erase process in response to an evaluation of a quantity of physical volumes to be secure data erased and a minimum queued threshold; and in response to said determination that one or more of said plurality of tape drives is to be reallocated, reallocating the one or more of said plurality of tape drives from the secure data erase process to another function. | 12-06-2012 |
