Abstract

Devices, systems, and methods for managing data processing systems are disclosed. The data processing systems may include hardware components that generate heat. The heat may be managed using flows of gasses. Filters may be used to screen particulates entrained in the flows of gasses. The data processing systems may include a system for managing accumulations of particulates over time. The system may refresh the filters over time by reducing the particulate accumulations on the filters.

First claim

What is claimed is:

1 . A method of managing hardware components positioned in a chassis of a data processing system, the method comprising and by a hardware processor of the data processing system:
identifying an occurrence of a particulate accumulation elimination event, the hardware processor being coupled to a memory of the data processing system, the memory storing instructions that when executed by the hardware processor causes the hardware processor to perform the method, and the hardware processor and memory being ones of the hardware components; based on the identifying of the occurrence:
activating a field applicator to apply an electric field to a filtration media of a filter covering an opening in a chassis of the data processing system to charge at least a portion of particulates accumulated on the filtration media to a charge level to obtain charged particulates, the opening facilitating airflow through the chassis to dissipate heat from the hardware components;
while the particulates are being charged to the charge level, identifying an occurrence of a charged particulates discharge event;
based on the occurrence of the charged particulates discharge event:
grounding at least a frame of the filter to discharge the charged particulates;
while grounding the at least the frame of the filter, identifying that the particulate accumulation elimination event has ended; and
deactivating the field applicator and allow the at least the frame to electrically float based on the end of the particulate accumulation elimination event.

2 . The method of claim 1 , wherein identifying the occurrence of the particulate accumulation eliminate event comprises, by the hardware processor:
monitoring operation of a cooling system of the data processing system to obtain at least one metric; and comparing the metric to a threshold to identify the occurrence of the particulate accumulation elimination event.

3 . The method of claim 2 , wherein the metric comprises one selected from a group of metrics consisting of:
a rate of the airflow through the chassis; and a power consumption rate of the cooling system for a given rate of the airflow through the chassis.

4 . The method of claim 1 , wherein a schedule of when to clear the particulates from the filtration media is maintained by the data processing system, and the occurrence of the particulate accumulation elimination is a point in time defined by the schedule.

5 . The method of claim 1 , wherein the field applicator comprises an electromagnet positioned with the filtration media, and the electric field is oriented through opening which the filtration media covers.

6 . The method of claim 1 , wherein the particulates comprise dust, and the data processing system is positioned in an edge installation that does not provide filtered air to the data processing system for cooling.

7 . The method of claim 1 , wherein identifying the occurrence of the charged particulates discharge event comprises, by the hardware processor:
monitoring operation of a cooling system of the data processing system while the field applicator is active to obtain at least second metric; and comparing the second metric to a threshold to identify the occurrence of the charged particulates discharge event.

8 . The method of claim 7 , wherein the second metric comprises one selected from a group of metrics consisting of:
a change in a rate of the airflow through the chassis; and a change in power consumption rate of the cooling system for a given rate of the airflow through the chassis.

9 . The method of claim 1 , wherein identifying the occurrence of the charged particulates discharge event comprises, by the hardware processor:
monitoring a duration of time during which the field applicator is active, wherein the charged particulates discharge event is predetermined duration of time while the field applicator is active.

10 . The method of claim 1 , wherein the filtration media has a pore size selected to screen the particulates from entering and interior of the chassis where the hardware components are loaded, and accumulation of the particulates on the filtration media fills at least a portion of pores of the filtration media.

11 . A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor of a data processing system, cause the processor to perform operations for managing hardware components positioned in a chassis of the data processing system, the operations comprising:
identifying an occurrence of a particulate accumulation elimination event, the processor being coupled to a memory of the data processing system, the memory comprising the non-transitory machine-readable medium, and the processor and the memory being ones of the hardware components of the data processing system; based on the identifying of the occurrence:
activating a field applicator to apply an electric field to a filtration media of a filter covering an opening in a chassis of the data processing system to charge at least a portion of particulates accumulated on the filtration media to a charge level to obtain charged particulates, the opening facilitating airflow through the chassis to dissipate heat from the hardware components;
while the particulates are being charged to the charge level, identifying an occurrence of a charged particulates discharge event;
based on the occurrence of the charged particulates discharge event:
grounding at least a frame of the filter to discharge the charged particulates;
while grounding the at least the frame of the filter, identifying that the particulate accumulation elimination event has ended; and
deactivating the field applicator and allow the at least the frame to electrically float based on the end of the particulate accumulation elimination event.

12 . The non-transitory machine-readable medium of claim 11 , wherein identifying the occurrence of the particulate accumulation eliminate event comprises:
monitoring operation of a cooling system of the data processing system to obtain at least one metric; and comparing the metric to a threshold to identify the occurrence of the particulate accumulation elimination event.

13 . The non-transitory machine-readable medium of claim 12 , wherein the metric comprises one selected from a group of metrics consisting of:
a rate of the airflow through the chassis; and a power consumption rate of the cooling system for a given rate of the airflow through the chassis.

14 . The non-transitory machine-readable medium of claim 11 , wherein a schedule of when to clear the particulates from the filtration media is maintained by the data processing system, and the occurrence of the particulate accumulation elimination is a point in time defined by the schedule.

15 . The non-transitory machine-readable medium of claim 11 , wherein the field applicator comprises an electromagnet positioned with the filtration media, and the electric field is oriented through opening which the filtration media covers.

16 . A data processing system, comprising:
