Abstract

A method for processing requests, that includes receiving, by a volatile storage component, a request from a user space application, writing the request into a shared memory partition, generating instructions associated with the request, and processing the instructions, where the request is a data request and where generating the instructions associated with the request includes detecting, by the volatile storage component, the data request in the shared memory partition, where the data request is written in a data queue.

Claims (37)

1. A method for processing requests, comprising:

receiving, by a volatile storage component, a request from a user space application, wherein the request is a management request, and wherein the management request is an erase request to erase all data on the volatile storage component;

writing the request into a shared memory partition;

generating instructions associated with the request, wherein generating the instructions associated with the request comprises:

detecting, by the volatile storage component, the management request in the shared memory partition, wherein the management request is written in a management queue; and

processing the instructions.

2. The method of claim 1 , wherein the request is a data request and wherein generating the instructions associated with the request comprises:

detecting, by the volatile storage component, the data request in the shared memory partition, wherein the data request is written in a data queue.

3. The method of claim 1 , wherein the management request is a storage health query for a non-volatile storage device operatively connected to the volatile storage component.

4. The method of claim 3 , wherein in response to processing the instructions:

the volatile storage component receives health data from the non-volatile storage device.

5. The method of claim 1 , wherein the management request further specifies erasing all data on a non-volatile storage device operatively connected to the volatile storage component.

6. A non-transitory computer readable medium comprising computer code which, when executed by a computer processor, enables the computer processor to perform a method for processing requests, comprising:

receiving, by a volatile storage component, a request from a user space application, wherein the request is a management request, and wherein the management request is an erase request to erase all data on the volatile storage component;

writing the request into a shared memory partition;

generating instructions associated with the request, wherein generating the instructions associated with the request comprises:

detecting, by the volatile storage component, the management request in the shared memory partition, wherein the management request is written in a management queue; and

processing the instructions.

7. The non-transitory computer readable medium of claim 6 , wherein the request is a data request and wherein generating the instructions associated with the request comprises:

detecting, by the volatile storage component, the data request in the shared memory partition, wherein the data request is written in a data queue.

8. The non-transitory computer readable medium of claim 6 , wherein the management request is a storage health query for a non-volatile storage device operatively connected to the volatile storage component.

9. The non-transitory computer readable medium of claim 8 , wherein in response to processing the instructions:

the volatile storage component receives health data from the non-volatile storage device.

10. The non-transitory computer readable medium of claim 6 , wherein the management request further specifies erasing all data on a non-volatile storage device operatively connected to the volatile storage component.

11. A volatile storage component, comprising:

volatile storage device;

shared memory partition; and

a processor, wherein the processor is configured to perform a method for processing requests, comprising:

receiving a request from a user space application, wherein the request is a management request, and wherein the management request is an erase request to erase all data on the volatile storage component;

writing the request into the shared memory partition;

generating instructions associated with the request, wherein generating the instructions associated with the request comprises:

detecting, by the volatile storage component, the management request in the shared memory partition, wherein the management request is written in a management queue; and

processing the instructions.

12. The volatile storage component of claim 11 , wherein the request is a data request and wherein generating the instructions associated with the request comprises:

detecting the data request in the shared memory partition, wherein the data request is written in a data queue.

13. The volatile storage component of claim 11 , wherein the management request is a storage health query for a non-volatile storage device operatively connected to the volatile storage component.

14. The volatile storage component of claim 13 , wherein in response to processing the instructions: the volatile storage component receives health data from the non-volatile storage device.
