Abstract
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.
Claims9
A tape management system comprising:
- a plurality of tape drives;
- and
- a processor coupled to said plurality of tape drives, wherein said processor is configured to:
- in response to said tape management system receiving a request to perform a secure data erase process, determine whether an allocation of an additional tape drive would improve secure data erase performance, said determination comprising an evaluation of a quantity of physical volumes to be secure data erased, a maximum queued threshold, an average tune to an erasure deadline, and a minimum expiration threshold;
- and
- in response to said determination that said allocation of an additional tape drive would improve said secure data erase performance, allocate an additional tape drive for said secure data erase process.
A tape management system comprising:
- a plurality of tape drives;
- and
- a processor coupled to said plurality of tape drives, wherein said processor is configured to:
- in response to said tape management system receiving a request to perform a secure data erase process, determine whether an allocation of an additional tape drive would improve secure data erase performance, said determination comprising an evaluation of 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;
- and
- in response to said determination that said allocation of an additional tape drive would improve said secure data erase performance, allocate an additional tape drive for said secure data erase process,
- wherein said quantity of physical volumes to be secure data erased is determined by a physical volume erase count, wherein said physical volume erase count is determined by incrementing a count for each physical volume that has a remaining time less than a time threshold.
A tape management system comprising:
- a plurality of tape drives;
- and
- a processor coupled to said plurality of tape drives, wherein said processor is configured to:
- in response to said tape management system receiving a request to perform a secure data erase process, determine whether an allocation of an additional tape drive would improve secure data erase performance, said determination comprising an evaluation of 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;
- and
- in response to said determination that said allocation of an additional tape drive would improve said secure data erase performance, allocate an additional tape drive for said secure data erase process,
- wherein said tape drives are configured to perform said secure data erase process by overwriting data of said physical volume.
