Abstract

A method, computer program product, and computing system for defining one or more user data portions and at least two reserved portions of a solid-state drive (SSD). An operating mode of the SSD may be determined. One or more of the at least two reserved portions of the SSD may be utilized based upon, at least in part, the operating mode of the SSD.

First claim

What is claimed is:

1. A computer-implemented method, executed on a computing device, comprising:
defining one or more user data portions and at least two reserved portions of a solid-state drive (SSD), wherein the at least two reserved portions of the SSD include a predefined over-provision portion and a predefined spare rebuild portion;
determining an operating mode of the SSD, wherein determining an operating mode of the SSD includes one or more of:
determining that the SSD is in normal mode;
determining that the SSD is in degraded mode; and
determining that the SSD is in recovery mode; and

utilizing one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD, wherein utilizing one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD includes one or more of:
utilizing one or more of the at least two reserved portions of the SSD for a file system consistency check (FSCK) tier; and
utilizing one or more of the at least two reserved portions of the SSD for a caching tier.

2. The computer-implemented method of claim 1 , wherein utilizing one or more of the at least two reserved portions of the SSD for the FSCK tier includes one or more of:
utilizing at least a portion of the predefined over-provision portion for the FSCK tier in response to determining that the SSD is in recovery mode; and
utilizing at least a portion of the predefined spare rebuild portion for the FSCK tier in response to determining that the SSD is in recovery mode.

3. The computer-implemented method of claim 1 , wherein utilizing one or more of the at least two reserved portions of the SSD for the caching tier includes:
utilizing at least a portion of the predefined spare rebuild portion for the caching tier in response to determining that the SSD is in normal mode.

4. The computer-implemented method of claim 1 , wherein utilizing one or more of the at least two reserved portions of the SSD for the caching tier includes:
utilizing at least a portion of the predefined over-provision portion for the caching tier in response to determining that the SSD is in degraded mode.

5. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
defining one or more user data portions and at least two reserved portions of a solid-state drive (SSD), wherein the at least two reserved portions of the SSD include a predefined over-provision portion and a predefined spare rebuild portion;
determining an operating mode of the SSD, wherein determining an operating mode of the SSD includes one or more of:
determining that the SSD is in normal mode;
determining that the SSD is in degraded mode; and
determining that the SSD is in recovery mode; and

utilizing one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD, wherein utilizing one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD includes one or more of:
utilizing one or more of the at least two reserved portions of the SSD for a file system consistency check (FSCK) tier; and
utilizing one or more of the at least two reserved portions of the SSD for a caching tier.

6. The computer program product of claim 5 , wherein utilizing one or more of the at least two reserved portions of the SSD for the FSCK tier includes one or more of:
utilizing at least a portion of the predefined over-provision portion for the FSCK tier in response to determining that the SSD is in recovery mode; and
utilizing at least a portion of the predefined spare rebuild portion for the FSCK tier in response to determining that the SSD is in recovery mode.

7. The computer program product of claim 5 , wherein utilizing one or more of the at least two reserved portions of the SSD for the caching tier includes:
utilizing at least a portion of the predefined spare rebuild portion for the caching tier in response to determining that the SSD is in normal mode.

8. The computer program product of claim 5 , wherein utilizing one or more of the at least two reserved portions of the SSD for the caching tier includes:
utilizing at least a portion of the predefined over-provision portion for the caching tier in response to determining that the SSD is in degraded mode.

9. A computing system comprising:
a memory; and
a processor configured to define one or more user data portions and at least two reserved portions of a solid-state drive (SSD), wherein the at least two reserved portions of the SSD include a predefined over-provision portion and a predefined spare rebuild portion, wherein the processor is further configured to determine an operating mode of the SSD, wherein determining an operating mode of the SSD includes one or more of: determining that the SSD is in normal mode, determining that the SSD is in degraded mode, and determining that the SSD is in recovery mode, and wherein the processor is further configured to utilize one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD, wherein utilizing one or more of the at least two reserved portions of the SSD based upon, at least in part, the operating mode of the SSD includes one or more of: utilizing one or more of the at least two reserved portions of the SSD for a file system consistency check (FSCK) tier, and utilizing one or more of the at least two reserved portions of the SSD for a caching tier.

10. The computing system of claim 9 , wherein utilizing one or more of the at least two reserved portions of the SSD for the FSCK tier includes one or more of:
utilizing at least a portion of the predefined over-provision portion for the FSCK tier in response to determining that the SSD is in recovery mode; and
utilizing at least a portion of the predefined spare rebuild portion for the FSCK tier in response to determining that the SSD is in recovery mode.

11. The computing system of claim 9 , wherein utilizing one or more of the at least two reserved portions of the SSD for the caching tier includes one or more of:
utilizing at least a portion of the predefined spare rebuild portion for the caching tier in response to determining that the SSD is in normal mode; and
utilizing at least a portion of the predefined over-provision portion for the caching tier in response to determining that the SSD is in degraded mode.
