Abstract

For power management in a disaggregated computing system, upon detecting an electrical power reduction to the disaggregated computing system, respective workloads being performed by respective processors within a set of processors are prioritized according to a service level agreement (SLA) of the respective workloads. Backup electrical power is dynamically allocated to the respective processors performing the respective workloads based upon a priority of the SLA of the respective workloads.

First claim

1 . A method for power management in a disaggregated computing system, by a processor device, comprising:
upon detecting a reduction in electrical power supplied to the disaggregated computing system, prioritizing respective workloads being performed by respective processors within a set of processors according to a service level agreement (SLA) of the respective workloads; wherein backup electrical power is dynamically allocated to the respective processors performing the respective workloads based upon a priority of the SLA of the respective workloads.

2 . The method of claim 1 , wherein dynamically allocating the backup electrical power includes adjusting an allocated voltage and clock speed of the respective processors within the set of processors.

3 . The method of claim 2 , further including maintaining the allocated voltage and clock speed of the respective processors performing the respective workloads having a higher priority SLA while reducing the allocated voltage and clock speed of the respective processors performing the respective workloads having a lower priority SLA.

4 . The method of claim 3 , further including, upon the detection of the electrical power reduction, stopping or suspending the performing of the respective workloads having the lower priority SLA until normal utility power is restored.

5 . The method of claim 3 , further including systemically shutting down the respective processors within the set of processors performing the respective workloads having the lower priority SLA upon the expiration of a predetermined time period while being supplied with the backup electrical power.

6 . The method of claim 5 , wherein systemically shutting down the respective processors further includes shutting down respective processors corresponding to respective regions, the regions associated with the respective workloads having the lower priority SLA.

7 . The method of claim 1 , wherein the backup electrical power is provided by at least one of an Uninterruptible Power Supply (UPS) and a backup generator.

8 . A system for power management in a disaggregated computing system, the system comprising:
at least one processor device, wherein the at least one processor device:
upon detecting a reduction in electrical power supplied to the disaggregated computing system, prioritizes respective workloads being performed by respective processors within a set of processors according to a service level agreement (SLA) of the respective workloads; wherein backup electrical power is dynamically allocated to the respective processors performing the respective workloads based upon a priority of the SLA of the respective workloads.

9 . The system of claim 8 , wherein dynamically allocating the backup electrical power includes adjusting an allocated voltage and clock speed of the respective processors within the set of processors.

10 . The system of claim 9 , wherein the at least one processor device maintains the allocated voltage and clock speed of the respective processors performing the respective workloads having a higher priority SLA while reducing the allocated voltage and clock speed of the respective processors performing the respective workloads having a lower priority SLA.

11 . The system of claim 10 , wherein the at least one processor device, upon the detection of the electrical power reduction, stopping or suspending the performing of the respective workloads having the lower priority SLA until normal utility power is restored.

12 . The system of claim 10 , wherein the at least one processor device systemically shuts down the respective processors within the set of processors performing the respective workloads having the lower priority SLA upon the expiration of a predetermined time period while being supplied with the backup electrical power.

13 . The system of claim 12 , wherein systemically shutting down the respective processors further includes shutting down respective processors corresponding to respective regions, the regions associated with the respective workloads having the lower priority SLA.

14 . The system of claim 8 , wherein the backup electrical power is provided by at least one of an Uninterruptible Power Supply (UPS) and a backup generator.

15 . A computer program product for power management in a disaggregated computing system, by a processor device, the computer program product embodied on a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that, upon detecting a reduction in electrical power supplied to the disaggregated computing system, prioritizes respective workloads being performed by respective processors within a set of processors according to a service level agreement (SLA) of the respective workloads; wherein backup electrical power is dynamically allocated to the respective processors performing the respective workloads based upon a priority of the SLA of the respective workloads.

16 . The computer program product of claim 15 , wherein dynamically allocating the backup electrical power includes adjusting an allocated voltage and clock speed of the respective processors within the set of processors.

17 . The computer program product of claim 16 , further including an executable portion that maintains the allocated voltage and clock speed of the respective processors performing the respective workloads having a higher priority SLA while reducing the allocated voltage and clock speed of the respective processors performing the respective workloads having a lower priority SLA.

18 . The computer program product of claim 17 , further including an executable portion that, upon the detection of the electrical power reduction, stopping or suspending the performing of the respective workloads having the lower priority SLA until normal utility power is restored.

19 . The computer program product of claim 17 , further including an executable portion that systemically shuts down the respective processors within the set of processors performing the respective workloads having the lower priority SLA upon the expiration of a predetermined time period while being supplied with the backup electrical power.

20 . The computer program product of claim 19 , wherein systemically shutting down the respective processors further includes shutting down respective processors corresponding to respective regions, the regions associated with the respective workloads having the lower priority SLA.

21 . The computer program product of claim 15 , wherein the backup electrical power is provided by at least one of an Uninterruptible Power Supply (UPS) and a backup generator.
