Abstract

Categorizing computing process output data streams for flash storage devices is disclosed. A first computing process characteristic of a first computing process that generates a first output data stream is determined. A structure that correlates the first computing process characteristic to a first stream identifier is accessed. A first filter driver is associated with the first computing process to configure the first filter driver to receive the first output data stream. The first filter driver is associated with a flash storage device. The first stream identifier is sent to the first filter driver.

Claims

1. A method for associating a stream identifier (ID) with an output data stream from a computing process, comprising:

determining, by a computing device comprising a processor device, a first computing process characteristic of a first computing process that generates a first output data stream;

accessing a structure that correlates the first computing process characteristic to a first stream ID;

associating a first filter driver with the first computing process to configure the first filter driver to receive the first output data stream, the first filter driver being associated with a flash storage device; and

sending the first stream ID to the first filter driver.

2. The method of claim 1 further comprising configuring the first filter driver to send the first output data stream to the flash storage device.

3. The method of claim 1 wherein the first computing process characteristic comprises a customer ID with which the first computing process is associated.

4. The method of claim 1 wherein the first computing process characteristic comprises a namespace with which the first computing process is associated.

5. The method of claim 1 further comprising:

determining a second computing process characteristic of a second computing process that generates a second output data stream;

accessing the structure;

determining that the structure correlates the second computing process characteristic to a second stream ID;

associating a second filter driver with the second computing process to configure the second filter driver to receive the second output data stream, the second filter driver being associated with the flash storage device; and

sending the second stream ID to the second filter driver.

6. The method of claim 5 wherein the second stream ID matches the first stream ID.

7. The method of claim 5 wherein the second stream ID is different from the first stream ID.

8. The method of claim 1 wherein the first computing process comprises a container process.

9. The method of claim 1 wherein the first computing process comprises a virtual machine.

10. A computing device for associating a stream identifier (ID) with an output data stream, comprising:

a communication interface to communicate with a network; and

a processor device coupled to the communication interface to;

access first information that correlates a first container process to a first stream ID;

associate a first filter driver with the first container process to configure the first filter driver to receive a first output data stream from the first container process, the first filter driver being associated with a flash storage device; and

send the first stream ID to the first filter driver.

11. The computing device of claim 10 wherein the processor device is further to configure the first filter driver to send the first output data stream to the flash storage device.

12. The computing device of claim 10 wherein the first information comprises a customer ID with which the first container process is associated.

13. The computing device of claim 10 wherein the first information comprises a namespace with which the first container process is associated.

14. The computing device of claim 10 wherein the processor device is further to:

determine second information that correlates a second container process to a second stream ID;

associate a second filter driver with the second container process to configure the second filter driver to receive a second output data stream from the second container process, the second filter driver being associated with the flash storage device; and

send the second stream ID to the second filter driver.

15. The computing device of claim 14 wherein the second stream ID matches the first stream ID.

16. The computing device of claim 14 wherein the second stream ID is different from the first stream ID.

17. A computer program product stored on a non-transitory computer-readable storage medium and including instructions to cause a processor device to:

determine, for each of a plurality of different computing processes associated with corresponding ones of a plurality of different tenants and executing on a same computing device, a corresponding stream identifier, each stream identifier being associated with a particular tenant;

associate a filter driver with each different computing process; and

associate each filter driver with a same flash storage device, each filter driver being configured to receive an output data stream from the computing process with which the respective filter driver is associated, and send the output data stream and the corresponding stream identifier to the same flash storage device.

18. The computer program product of claim 17 wherein the plurality of different computing processes comprise container processes.

19. The computer program product of claim 17 wherein the plurality of different computing processes comprise virtual machines.

20. The computer program product of claim 17 wherein to determine the corresponding stream identifiers the instructions further cause the processer device to, for each respective computing process of the plurality of different computing processes:

determine a computing process characteristic of the respective computing process; and

access a structure that correlates the computing process characteristic to the corresponding stream identifier.
