Minimizing airflow using preferential memory allocation by prioritizing memory workload allocation to memory banks according to the locations of memory banks within the enclosure

摘要

One embodiment provides a method of controlling memory in a computer system. Airflow is generated through an enclosure at a variable airflow rate to cool a plurality of memory banks at different locations within the enclosure. The airflow rate is controlled as a function of the temperature of one or more of the memory banks. Memory workload is selectively allocated to the memory banks according to expected differences in airflow, such as differences in airflow temperature, at each of the different locations.

1. A method of controlling memory in a computer system, comprising:
generating airflow through an enclosure at a variable airflow rate to cool a plurality of memory banks at different locations within the enclosure; controlling the airflow rate as a function of the temperature of one or more of the memory banks; selectively allocating memory workload to the memory banks according to expected differences in airflow at each of the different locations; and providing an electronic table to the operating system, the electronic table providing a prioritization by which to allocate the memory workload to the memory banks according to the locations of the memory banks within the enclosure; wherein the prioritization provided by the electronic table specifies a range of higher to lower prioritization levels, by which a memory bank at a higher prioritization level is designated to receive a greater volume or intensity of workload than a memory bank at a lower prioritization level.
