Abstract

A data storage device and method are provided for accommodating data of a third-party system. In one embodiment, a data storage device is provided comprising a memory and one or more processors. The one or more processors, individually or in combination, are configured to: receive data from a graphics processing unit (GPU) of a host; segregate the data; determine whether the host is pre-approved for a capacity condition; and in response to determining that the host is pre-approved for the capacity condition: associate the segregated data per a pre-approved destination; and consolidate logical-to-physical address entry updates into a logical-to-physical address data structure. Other embodiments are provided.

Claims (59)

1 . A data storage device comprising:

a memory; and

one or more processors, individually or in combination, configured to:

receive data and a logical address directly from a graphics processing unit (GPU) of a host as opposed to indirectly through a central processing unit (CPU) of the host;

store the data in a location of the memory configured to store only data received from the GPU as opposed to data received from the CPU;

store an entry in a secondary logical-to-physical address data structure to reflect that the data is stored in the location in the memory, wherein the secondary logical-to-physical address data structure stores only entries for the location in the memory as opposed to other locations in the memory that store data received from the CPU;

determine whether the data is pre-approved for a capacity condition;

in response to determining that the data is not pre-approved for the capacity condition:

discard the entry in the secondary logical-to-physical address data structure; and

perform garbage collection only in the location in the memory as opposed to the other locations in the memory; and

in response to determining that the data is pre-approved for the capacity condition: merge the secondary logical-to-physical address data structure into a primary logical-to-physical address data structure that stores entries for the other locations in the memory.

2 . The data storage device of claim 1 , wherein the data is received with a GPU identifier.

3 . The data storage device of claim 1 , wherein the logical address is part of a logical block address (LBA) range associated with the GPU.

4 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to:

move the data to capacity blocks.

5 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to:

monitor input-output data of the GPU and at least one additional GPU; and

route the input-output data based on an instruction from the host.

6 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to:

monitor input-output data of the GPU and at least one additional GPU; and

generate parity for the input-output data based on an instruction from the host.

7 . The data storage device of claim 1 , wherein the one or more processors, individually or in combination, are further configured to:

monitor input-output data of the GPU and at least one additional GPU; and

perform quality-of-service biasing of the input-output data based on an instruction from the host.

8 . The data storage device of claim 1 , wherein the memory comprises a three-dimensional memory.

9 . A method comprising:

performing in a data storage device comprising a memory:

receiving data and a logical address directly from a graphics processing unit (GPU) of a host as opposed to indirectly through a central processing unit (CPU) of the host;

storing the data in a location of the memory configured to store only data received from the GPU as opposed to data received from the CPU;

storing an entry in a secondary logical-to-physical address data structure to reflect that the data is stored in the location in the memory, wherein the secondary logical-to-physical address data structure stores only entries for the location in the memory as opposed to other locations in the memory that store data received from the CPU;

determining whether the host is pre-approved for a capacity condition;

in response to determining that the host is pre-approved for the capacity condition:

discarding the entry in the secondary logical-to-physical address data structure; and

performing garbage collection only in the location in the memory as opposed to the other locations in the memory; and

in response to determining that the data is pre-approved for the capacity condition: merging the secondary logical-to-physical address data structure into a primary logical-to-physical address data structure that stores entries for the other locations in the memory.

10 . The method of claim 9 , wherein the data is received with a GPU identifier.

11 . The method of claim 9 , wherein the logical address is part of a logical block address (LBA) range associated with the GPU.

12 . The method of claim 9 , further comprising:

moving the data to capacity blocks.

13 . The method of claim 9 , further comprising:

monitoring input-output data of the GPU and at least one additional GPU; and

routing the input-output data based on an instruction from the host.

14 . The method of claim 9 , further comprising:

monitoring input-output data of the GPU and at least one additional GPU; and

generating parity for the input-output data based on an instruction from the host.

15 . The method of claim 9 , further comprising:

monitoring input-output data of the GPU and at least one additional GPU; and

performing quality-of-service biasing of the input-output data based on an instruction from the host.

16 . A data storage device comprising:

a memory; and

means for:

receiving data and a logical address directly from a graphics processing unit (GPU) of a host as opposed to indirectly through a central processing unit (CPU) of the host;

storing the data in a location of the memory configured to store only data received from the GPU as opposed to data received from the CPU;

storing an entry in a secondary logical-to-physical address data structure to reflect that the data is stored in the location in the memory, wherein the secondary logical-to-physical address data structure stores only entries for the location in the memory as opposed to other locations in the memory that store data received from the CPU;

determining whether the host is pre-approved for a capacity condition;

in response to determining that the host is pre-approved for the capacity condition:

discarding the entry in the secondary logical-to-physical address data structure; and

performing garbage collection only in the location in the memory as opposed to the other locations in the memory; and

in response to determining that the host is pre-approved for the capacity condition: merging the secondary logical-to-physical address data structure into a primary logical-to-physical address data structure that stores entries for the other locations in the memory.
