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 |
20090083510 | METHOD, SYSTEM, AND ARTICLE OF MANUFACTURE FOR RETURNING PHYSICAL VOLUMES - Provided are a method, system and article of manufacture for return processing in storage pools. A plurality of physical volumes are allocated to a first storage pool. A determination is made whether the first storage pool has more than a threshold number of empty physical volumes. If the first storage pool has more than the threshold number of empty physical volumes, then at least one empty physical volume is returned to a second storage pool. | 03-26-2009 |
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 |
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 |
