Abstract

Systems for managing resources for maintenance tasks in computing systems are provided. One system includes a controller and memory coupled to the controller, the memory configured to store a module. The controller, when executing the module, is configured to determine an amount of available resources for use by a plurality of maintenance tasks in a computing system and divide the available resources between the plurality of maintenance tasks based on a need for each maintenance task. One method includes determining, by a central controller, an amount of available resources for use by a plurality of maintenance tasks in a computing system and dividing the available resources between the plurality of maintenance tasks based on a need for each maintenance task. Computer storage mediums including a computer program product method for managing resources for maintenance tasks in computing systems are also provided.

Claims

1. A system for managing resources for maintenance tasks, comprising:

a controller; and

memory coupled to the controller, the memory configured to store a module, wherein, when executing the module, the controller is configured to;

determine an amount of available resources for use by a plurality of maintenance tasks in a computing system, and

divide the available resources between the plurality of maintenance tasks based on a need for each maintenance task and based on a type of rate limit for each respective maintenance task, wherein, when dividing the available resources, the controller is configured to;

assign a first percentage of the available resources to a first maintenance task,

assign a second percentage of the available resources to a second maintenance task,

translate the first percentage to a nominal rate for performing the first maintenance task, and

translate the second percentage to a physical rate for performing the second maintenance task.

2. The system of claim 1, wherein, when determining the amount of available resources, the controller is configured to determine a nominal throughput of the computing system.

3. The system of claim 1, wherein, when determining the amount of available resources, the controller is configured to determine a number of input/output operations performed by the computing system within a predetermined amount of time.

4. The system of claim 1,

wherein the first percentage and the second percentage are determined based on the maintenance needs of the computing system at a particular point in time.

5. A physical computer storage medium comprising a computer program product method for managing resources for maintenance tasks in computing systems, the physical computer storage medium comprising:

computer code for determining, by a central controller, an amount of available resources for use by a plurality of maintenance tasks in a computing system; and

computer code for dividing, by the central controller, the available resources between the plurality of maintenance tasks based on a need for each maintenance task and based on a type of rate limit for each respective maintenance task, wherein the computer coded for dividing the available resources comprises computer code for;

computer code for assigning a first percentage of the available resources to a first maintenance task,

computer code for assigning a second percentage of the available resources to a second maintenance task,

computer code for translating the first percentage to a nominal rate for performing the first maintenance task, and

computer code for translating the second percentage to a physical rate for performing the second maintenance task.

6. The physical computer storage medium of claim 5, wherein the computer code for determining the amount of available resources comprises computer code for determining a nominal throughput of the computing system.

7. The physical computer storage medium of claim 5, wherein the computer code for determining the amount of available resources comprises computer code for determining a number of input/output operations performed by the system within a predetermined amount of time.

8. The of physical computer storage medium claim 5,

wherein the first percentage and the second percentage are determined based on the maintenance needs of the computing system at a particular point in time.
