Abstract

Methods 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 method for managing resources for maintenance tasks in computing systems, the method comprising:

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

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 dividing the available resources comprises;

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

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

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

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

2. The method of claim 1, wherein determining the amount of available resources comprises determining a nominal throughput of the computing system.

3. The method of claim 1, wherein determining the amount of available resources comprises determining a number of input/output operations performed by the computing system within a predetermined amount of time.

4. The method 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.
