Abstract
The advanced management module services in a data processing system are configured to determine the system load and provide an input to the early power off warning detection logic that evaluates the power system state to detect a condition when power resources are insufficient to maintain the write caching storage system power within defined acceptable limits. The early power off warning detection logic generates a notification based on the system load and the available power supply resources to maintain maximum availability and reliability characteristics.
Claims20
An apparatus, comprising:
- a processor;
- and
- a memory coupled to the processor, wherein the memory comprises:
- first instructions to identify a power configuration for a data processing system;
- second instructions to determine a load condition for the identified power configuration;
- third instructions to determine whether the load condition and power configuration is likely to result in an unreliable power system configuration for a write caching storage system;
- and
- fourth instructions to send a notification, in response to the load condition and power configuration being likely to result in an unreliable power system configuration for the write caching storage system, to the write caching storage system indicating the unreliable power system configuration.
A computer program product comprising:
- a computer readable storage medium;
- first program instructions to identify a power configuration for a data processing system;
- second program instructions to determine a load condition for the identified power configuration;
- third program instructions to determine whether the load condition and power configuration is likely to result in an unreliable power system configuration for a write caching storage system;
- and
- fourth program instructions to send a notification, in response to the load condition and power configuration being likely to result in an unreliable power system configuration for the write caching storage system, to the write caching storage system indicating the unreliable power system configuration;
- and
- wherein the first, second, third, and fourth program instructions are stored on the computer readable storage medium.
A method, implemented in a hardware module, comprising:
- identifying, by the hardware module, by the a power configuration for a data processing system;
- determining, by the hardware module, a load condition for the identified power configuration;
- determining, by the hardware module, whether the load condition and power configuration is likely to result in an unreliable power system configuration for a write caching storage system;
- and
- sending, by the hardware module, a notification, in response to the load condition and power configuration being likely to result in an unreliable power system configuration for the write caching storage system, to the write caching storage system indicating the unreliable power system configuration.
