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 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, by the computing device, a structure that correlates the first computing process characteristic to a first stream ID;

associating, by the computing device, 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 being configured to send the first output data stream received from the first computing process and the first stream ID to a device driver associated with the flash storage device; and

sending, by the computing device, the first stream ID to the first filter driver.
