Power state adjustment

1. A system comprising:

at least one power controller for controlling power consumption of respective devices of a plurality of devices in a target system, wherein:

the at least one power controller receives a power setting request for the target system; and

the at least one power controller determines which devices of the plurality of devices can be slowed down, speeded up, turned off, turned on, or suspended, based on at least:

the received power setting request;

priority levels of respective applications that are running on the respective devices;

real-time load information including incoming requests to the plurality of devices; and

impact on performance of respective applications that are running on the respective devices.

2. The system of claim 1 , further comprising one or more controllers in communication with the at least one power controller to move workload from a first subset of devices in the target system to a second subset of devices in the target system.

3. The system of claim 2 , wherein the at least one power controller communicates with the one or more controllers to put selected devices in the target system in any one mode from: 1) available mode, 2) unavailable mode, 3) suspended mode, 4) maintenance mode, 5) partially available mode, and 6) any mode that is supported by the one or more controllers.

4. The system of claim 1 , wherein the at least one power controller analyzes and controls one or more of: 1) nature and importance of applications running on a respective device, 2) workloads in the target system at a given period of time, 3) business units that may be affected by changes in power adjustment of respective devices, 4) cost of power consumption at a given time of day or year, 5) amount of power available at a given time of day, 6) peak demand thresholds, 7) business goals at a given period of time, 8) environmental factors in the target system, 9) location of a respective device in the target system, 10) work load types, 11) physical location of a respective device in the target system, 12) logical location of a respective device in a power supply chain, 13) name of the respective application, 14) ID of device associated with a respective application, 15) ID of one or more uninterruptible power units, 16) power outlet IDs, 17) types of redundancies associated with the target system, 18) number of redundancies associated with the target system, 19) types power supply failures, 20) frequency of power supply failures, and 21) environmental factors.

5. The system of claim 1 , wherein the target system comprises one or more of: 1) virtual servers, 2) physical servers, 3) switches, 4) firewalls, 5) routers, 6) server pools, 7) application pools, 8) software defined networking solutions, 9) controllers, 10) management modules, and 11) environmental control device.

6. The system of claim 1 , wherein the at least one power controller is involved in identifying which applications, application pools, company departments or workloads would be impacted by non-operation of one or more devices in the target system.

7. The system of claim 1 , wherein the at least one power controller is involved in identifying which devices can be shut down or should be shut down, should be turned on or have their power state increased or have their mode of operation altered if there is a change in availability in supply of power to the target system.

8. The system of claim 1 , wherein the at least one power controller is involved in identifying which devices can have their power state reduced and/or have their mode of operation altered so as to redirect power to devices that are running critical applications.

9. The system of claim 1 , wherein the at least one power controller monitors and analyzes the target system to recommend power saving strategies to achieve power savings.
