Abstract

A method, computer program product, and computing system for identifying a first memory device source that includes first content; identifying a second memory device source that include second content; and initiating a first iteration of a memory device cleansing procedure wherein first content and at least a first portion of the second content are moved to a first unused memory device.

First claim

What is claimed is:

1. A computer-implemented method, executed on a computing device, comprising:
identifying a first memory device source that includes first content;
identifying a second memory device source that include second content; and
initiating a first iteration of a memory device cleansing procedure wherein the first content and at least a first portion of the second content are moved to a first unused memory device to generate an unutilized memory device source,
wherein the first and the second memory device sources are identified for processing if a utilization level of the first memory device source is compatible with a utilization level of the second memory device source,
wherein one or more of the identifying a first memory device source and a second memory device source includes identifying a backpointer utilization level fora backpointer associated with a respective memory device source based, at least in part, upon an estimated usage of the respective memory device source, and
wherein the backpointer associated with the respective memory device source is configured to map a physical memory space of the respective memory device source to a virtual memory space of the respective memory device source.

2. The computer-implemented method of claim 1 further comprising:
identifying a third memory device source that includes third content; and
initiating a second iteration of the memory device cleansing procedure wherein at least a second portion of the second content and at least a first portion of the third content are moved to a second unused memory device.

3. The computer-implemented method of claim 2 further comprising:
identifying additional memory device sources that include additional content; and
initiating additional iterations of the memory device cleansing procedure wherein portions of the additional content are moved from the additional memory device sources to additional unused memory devices.

4. The computer-implemented method of claim 1 wherein one or more of the identifying a first memory device source and a second memory device source includes:
identifying a utilization level of the respective memory device source.

5. The computer-implemented method of claim 1 wherein one or more of the identifying a first memory device source and a second memory device source includes:
identifying a backpointer utilization level fora backpointer associated with the memory device source based, at least in part, upon an actual usage of the respective memory device source.

6. The computer-implemented method of claim 1 wherein identifying a first or second memory device source includes:
identifying a backpointer utilization level fora backpointer associated with the respective memory device source based, at least in part, upon a mapped page count of the backpointer.

7. 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:
identifying a first memory device source that includes first content;
identifying a second memory device source that include second content; and
initiating a first iteration of a memory device cleansing procedure wherein first content and at least a first portion of the second content are moved to a first unused memory device to generate an unutilized memory device source,
wherein the first and the second memory device sources are identified for processing if a utilization level of the first memory device source is compatible with a utilization level of the second memory device source,
wherein one or more of the identifying a first memory device source and a second memory device source includes identifying a backpointer utilization level fora backpointer associated with a respective memory device source based, at least in part, upon an estimated usage of the respective memory device source, and
wherein the backpointer associated with the respective memory device source is configured to map a physical memory space of the respective memory device source to a virtual memory space of the respective memory device source.

8. The computer program product of claim 7 further comprising:
identifying a third memory device source that includes third content; and
initiating a second iteration of the memory device cleansing procedure wherein at least a second portion of the second content and at least a first portion of the third content are moved to a second unused memory device.

9. The computer program product of claim 8 further comprising:
identifying additional memory device sources that include additional content; and
initiating additional iterations of the memory device cleansing procedure wherein portions of the additional content are moved from the additional memory device sources to additional unused memory devices.

10. The computer program product of claim 7 wherein one or more of the identifying a first memory device source and a second memory device source includes:
identifying a utilization level of the respective memory device source.

11. The computer program product of claim 7 wherein one or more of the identifying first memory device source and a second memory device source includes:
identifying a backpointer utilization level fora backpointer associated with the respective memory device source based, at least in part, upon an actual usage of the one or more of the first memory device source and the second memory device source memory device source.

12. The computer program product of claim 7 wherein one or more of the identifying a first memory device source and a second memory device source includes:
identifying a backpointer utilization level fora backpointer associated with the respective memory device source based, at least in part, upon a mapped page count of the backpointer.

13. A computing system including a processor and memory configured to perform operations comprising:
identifying a first memory device source that includes first content;
identifying a second memory device source that include second content; and
initiating a first iteration of a memory device cleansing procedure wherein first content and at least a first portion of the second content are moved to a first unused memory device to generate an unutilized memory device source,
wherein the first and the second memory device sources are identified for processing if a utilization level of the first memory device source is compatible with a utilization level of the second memory device source,
wherein one or more of the identifying a first memory device source and a second memory device source includes identifying a backpointer utilization level fora backpointer associated with a respective memory device source based, at least in part, upon an estimated usage of the respective memory device source, and
wherein the backpointer associated with the respective memory device source is configured to map a physical memory space of the respective memory device source to a virtual memory space of the respective memory device source.

14. The computing system of claim 13 further comprising:
identifying a third memory device source that includes third content; and
initiating a second iteration of the memory device cleansing procedure wherein at least a second portion of the second content and at least a first portion of the third content are moved to a second unused memory device.

15. The computing system of claim 14 further comprising:
identifying additional memory device sources that include additional co
