Abstract
Various embodiments for improving tape drive efficiency using a processor device are provided. In one embodiment, a method comprises aggregating one of records and filemarks, the aggregating restricted to being performed only on read operations, from a plurality of data segments into at least one single data segment, including sequentially aggregating the one of the records and filemarks into the at least one single data segment.
Claims21
A method for improving tape drive efficiency using a processor device, the method comprising:
- aggregating one of records and filemarks, the aggregating restricted to being performed only on read operations, from a plurality of data segments into at least one single data segment, including sequentially aggregating the one of the records and filemarks into the at least one single data segment.
A system for improving tape drive efficiency, the system comprising:
- a tape,
- the tape drive, in communication with the tape head,
- a plurality of buffers in communication with the tape and the tape drive, and
- a processor device, controlling the plurality of buffers, the tape, and the tape drive, wherein the processor device:
- aggregates one of records and filemarks, the aggregating restricted to being performed only on read operations, from a plurality of data segments into at least one single data segment, including sequentially aggregating the one of the records and filemarks into the at least one single data segment.
A computer program product for improving tape drive efficiency by a processor device, the computer program product embodied on a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
- a first executable portion that aggregates one of records and filemarks, the aggregating restricted to being performed only on read operations, from a plurality of data segments into at least one single data segment, including sequentially aggregating the one of the records and filemarks into the at least one single data segment.
