System method for improving read command process times in solid-state drives (SSD) by having processor split-up background writes based on determined command size
Mechanisms for improving read command processing times in a solid-state drive (SSD) are provided, the mechanisms comprising: determining a workload type of an SSD; in response to determining that the workload type is a pure read workload type: determining at least one command size into which an original background write is to be split-up using at least one hardware processor; and splitting-up the background write into a plurality of split background writes, each having one of the determined at least one command size. In some embodiments, the at least one command size accounts for a page of the physical medium of the SSD. In some embodiments, the at least one command size includes at least two different sizes. In some embodiments, the mechanisms further comprise combining two or more split background writes. In some embodiments, the original background write is split-up before being placed in a channel queue.
1. A system for improving read command processing times in a solid-state drive (SSD), comprising:
memory; and
at least one hardware processor collectively configured to at least:
determine a workload type of an SSD;
in response to determining that the workload type is a pure read workload type:
determine at least one command size into which an existing background write is to be split-up; and
split-up the existing background write into a plurality of split background writes, each having one of the determined at least one command size; and
combine two or more split background writes.
2. The system of claim 1 , wherein the at least one command size accounts for a page of the physical medium of the SSD.
3. The system of claim 1 , wherein the at least one command size includes at least two different sizes.
4. The system of claim 1 , wherein the existing background write is split-up before being placed in a channel queue.
5. The system of claim 1 , wherein the existing background write is split-up after being placed in a channel queue.
6. A method for improving read command processing times in a solid-state drive (SSD), comprising:
determining a workload type of an SSD;
in response to determining that the workload type is a pure read workload type:
determining at least one command size into which an existing background write is to be split-up using at least one hardware processor;
splitting-up the existing background write into a plurality of split background writes, each having one of the determined at least one command size; and
combining two or more split background writes.
7. The method of claim 6 , wherein the at least one command size accounts for a page of the physical medium of the SSD.
8. The method of claim 6 , wherein the at least one command size includes at least two different sizes.
9. The method of claim 6 , wherein the existing background write is split-up before being placed in a channel queue.
10. The method of claim 6 , wherein the existing background write is split-up after being placed in a channel queue.
11. A non-transitory computer-readable medium containing computer executable instructions that, when executed by a processor, cause the processor to perform a method for improving read command processing times in a solid-state drive (SSD), the method comprising:
determining a workload type of an SSD;
in response to determining that the workload type is a pure read workload type:
determining at least one command size into which an existing background write is to be split-up; and
splitting-up the existing background write into a plurality of split background writes, each having one of the determined at least one command size; and
combining two or more split background writes.
12. The non-transitory computer-readable medium of claim 11 , wherein the at least one command size accounts for a page of the physical medium of the SSD.
13. The non-transitory computer-readable medium of claim 11 , wherein the at least one command size includes at least two different sizes.
14. The non-transitory computer-readable medium of claim 11 , wherein the existing background write is split-up before being placed in a channel queue.
15. The non-transitory computer-readable medium of claim 11 , wherein the existing background write is split-up after being placed in a channel queue.
