Abstract

A computer-implemented method according to one embodiment includes receiving at a storage drive, from a host, a data request, implementing the data request at the storage drive, utilizing a streaming mode, and returning, by the storage drive, a confirmation to the host, in response to implementing the data request at the storage drive utilizing the streaming mode.

Claims (26)

1. A computer-implemented method, comprising:

receiving at a storage drive, from a host, a request for a data read;

implementing the data read at the storage drive, utilizing a streaming mode, including reading requested data in a single attempt at a specified speed without performing back-hitching; and

returning, by the storage drive, a confirmation to the host, in response to implementing the data read at the storage drive utilizing the streaming mode.

2. The computer-implemented method of claim 1 , wherein the data read is implemented utilizing the streaming mode in response to QoS information associated with the data request.

3. The computer-implemented method of claim 1 , wherein the data read is implemented utilizing the streaming mode in response to a selection of a setting for the storage drive.

4. The computer-implemented method of claim 1 , wherein implementing the data read further includes reading the data from a tape cartridge, utilizing the streaming mode.

5. The computer-implemented method of claim 1 , wherein implementing the data read at the storage drive utilizing the streaming mode further includes identifying a location on a data cartridge where requested data is located.

6. The computer-implemented method of claim 1 , wherein implementing the data read at the storage drive utilizing the streaming mode further includes continuing a reading of the data from a data cartridge at a predetermined speed in response to determining one or more errors during the reading of the data from the data cartridge.

7. The computer-implemented method of claim 1 , wherein implementing the data read at the storage drive utilizing the streaming mode further includes applying advanced data detection at a storage drive during a reading of the data.

8. The computer-implemented method of claim 1 , wherein implementing the data read at the storage drive utilizing the streaming mode further includes implementing iterative ECC decoding during a reading of the data, according to a predetermined latency threshold.

9. The computer-implemented method of claim 1 , wherein the confirmation includes a portion of data requested to be read, and one or more identifiers for portions of data that could not be read successfully.

10. The computer-implemented method of claim 1 , wherein the confirmation includes a summary of results of implementing the data read at the storage drive utilizing the streaming mode, and more detailed information is stored at the storage drive or another device, and is made available to the host in response to a request.

11. The computer-implemented method of claim 1 , wherein the confirmation includes an indication that one or more errors have been encountered by the storage drive, as well as data read after the one or more errors have been encountered.

12. The computer-implemented method of claim 1 , wherein the confirmation includes an indication that one or more errors have been encountered by the storage drive, as well as a confirmation of data written after the one or more errors have been encountered.

13. The computer-implemented method of claim 1 , wherein the confirmation includes only an indication that one or more errors have been encountered by the storage drive.

14. A computer program product for implementing a storage drive utilizing a streaming mode, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processor to cause the processor to perform a method comprising:

receiving, by the processor at a storage drive, from a host, a request for a data read;

implementing, by the processor, the data read at the storage drive, utilizing a streaming mode, including reading requested data by the processor in a single attempt at a specified speed without performing back-hitching; and

returning, by the processor at the storage drive, a confirmation to the host, in response to implementing the data read at the storage drive utilizing the streaming mode.

15. The computer program product of claim 14 , wherein the data read is implemented utilizing the streaming mode in response to QoS information associated with the request.

16. The computer program product of claim 14 , wherein the data read is implemented utilizing the streaming mode in response to a selection of a setting for the storage drive.

17. A computer-implemented method, comprising:

receiving at a storage drive, from a host, a request for a data write;

implementing the data write at the storage drive, utilizing a streaming mode, including writing the data to a data cartridge at the storage drive without stopping due to errors; and

returning, by the storage drive, a confirmation to the host, in response to implementing the data write at the storage drive utilizing the streaming mode.
