Abstract

Claims (64)

1. A method comprising:

identifying a state associated with a first storage device;

based on identifying the state:

determining that a first region associated with the first storage device is associated with a first attribute, and that a second region associated with the first storage device is associated with a second attribute;

identifying, at a second storage device, a first read command for first data;

identifying, based on the first read command, that the first data is stored in the first storage device;

based on identifying that the first data is stored in the first storage device:

determining that the first data is stored in the first region or the second region;

based on determining that the first data is stored in the first region, returning a first response to the first read command; and

based on determining that the first data is stored in the second region, returning a second response to the first read command.

2. The method of claim 1 , wherein the method further comprises:

identifying a second read command;

identifying, based on the second read command, second data stored in the first region of the first storage device; and

returning a message based on the identifying of the second data in the first region.

3. The method of claim 1 , further comprising:

identifying a write command;

writing at least a portion of second data to a cache of a computing device;

determining that the portion of the second data is associated with a third attribute; and

writing the second data to a persistent memory of the second storage device based on the determining that the portion of the second data is associated with the third attribute.

4. The method of claim 3 , wherein the third attribute includes identification of an association of the second data with the first region of the first storage device.

5. The method of claim 1 further comprising:

transmitting the first data from the first storage device to the second storage device.

6. The method of claim 1 , wherein the first attribute includes identification of first accessibility of the first region by a computing device, and the second attribute includes identification of second accessibility of the second region by the computing device.

7. The method of claim 1 , wherein the first data is associated with at least one virtual machine of a computing device.

8. The method of claim 1 , wherein the state includes a mode of operation of the first storage device.

9. The method of claim 8 , wherein the mode of operation includes at least one of a read-only mode, or a partial read-only mode.

10. A device comprising:

at least one memory device that stores computer-executable instructions; and

at least one processor configured to access the at least one memory device, wherein the at least one processor is configured to execute the computer-executable instructions to:

identify a state associated with a first storage device;

based on the processor being configured to identify the state, the processor is further configured to:

determine that a first region associated with the first storage device is associated with a first attribute, and that a second region associated with the first storage device is associated with a second attribute;

identify, at a second storage device, a first read command for first data;

identify, based on the first read command, that the first data is stored in the first storage device;

based on the processor being configured to identify that the first data is stored in the first storage device:

determine that the first data is stored in the first region or the second region;

based on the processor being configured to determine that the first data is stored in the first region, return a first response to the first read command; and

based on the processor being configured to determine that the first data is stored in the second region, return a second response to the first read command.

11. The device of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to:

identify a second read command;

identify, based on the second read command, second data stored in the first region of the first storage device; and

return a message based on the processor being configured to identify the second data in the first region.

12. The device of claim 10 , wherein the at least one processor is further configured to execute the computer-executable instructions to:

identify a write command;

write at least a portion of second data to a cache of a computing device;

determine that the portion of the second data is associated with a third attribute; and

write the second data to a persistent memory of the second storage device based on the at least one processor being configured to execute the computer-executable instructions to determine that the portion of the second data is associated with the third attribute.

13. The device of claim 12 , wherein the third attribute includes identification of an association of the second data with the first region of the first storage device.

14. The device of claim 10 , wherein the at least one processor is configured to execute computer-executable instructions to transmit the first data from the first storage device to the second storage device.

15. The device of claim 10 , wherein the first attribute includes identification of first accessibility of the first region by a computing device, and the second attribute includes identification of second accessibility of the second region by the computing device.

16. The device of claim 10 , wherein the state includes a mode of operation of the first storage device.

17. The device of claim 16 , wherein the mode of operation includes at least one of a read-only mode, or a partial read-only mode.

18. A non-transitory computer-readable medium storing computer-executable instructions which, when executed by a processor, cause the processor to perform operations comprising:

identifying a state associated with a first storage device;

based on identifying the state:

determining that a first region associated with the first storage device is associated with a first attribute, and that a second region associated with the first storage device is associated with a second attribute;

identifying a first read command for first data at a second storage device;

identifying, based on the first read command, that the first data is stored in the first storage device;

based on identifying that the first data is stored in the first storage device:

determining that the first data is stored in the first region or the second region;

based on determining that the first data is stored in the first region, returning a first response to the first read command; and

based on determining that the first data is stored in the second region, returning a second response to the first read command.

19. The non-transitory computer-readable medium of claim 18 , wherein the state includes a mode of operation of the first storage device.

20. The non-transitory computer-readable medium of claim 18 , wherein the first attribute includes identification of first accessibility of the first region by a computing device, and the second attribute includes identification of second accessibility of the second region by the computing device.
