Abstract
A system and method for designing aspects of a cooling system for a data center is provided. A method is provided including computing cooling redundancy at each rack position in a data center, in real time. The redundancy can be reported using the traditional N+1, N+2, etc. notation, where N is the number of coolers required to meet the primary cooling load type specification. The method substantially reduces the computational complexity of computing cooling redundancy.
Claims18
A computer-implemented method of determining cooling redundancy information, comprising:
- modeling in a computer a location having plural racks of equipment to be cooled by a plurality of coolers;
- for each rack:
- computing a fraction of the rack's airflow handled by a cooler;
- sorting by magnitude over the plurality of coolers one or more computed fractions including each computed fraction of the rack's airflow handled by a cooler;
- computing a surplus cooling factor;
- multiplying at least one of the one or more computed fractions by the surplus cooling factor to generate a modified computed fraction;
- computing a sum by adding the one or more modified computed fractions from smallest to largest until a cooling index for the rack is adequate, while keeping a count of coolers whose modified computed fractions are not included in the sum;
- and
- reporting redundancy as a value determined by the count.
A computer-implemented apparatus for determining cooling redundancy information, comprising:
- a computer storage system in which is held a numerical computer model representing a location having plural racks of equipment to be cooled by a plurality of coolers;
- and
- a computer processor executing a sequence of instructions directing:
- for each rack represented in the numerical computer model:
- computing a fraction of the rack's airflow handled by a cooler;
- sorting by magnitude over the plurality of coolers one or more computed fractions including each computed fraction of the rack's airflow handled by a cooler;
- computing a surplus cooling factor;
- multiplying at least one of the one or more computed fractions by the surplus cooling factor to generate a modified computed fraction;
- computing a sum by adding the one or more modified computed fractions from smallest to largest until a cooling index for the rack is adequate, while keeping a count of coolers whose modified computed fractions are not included in the sum;
- and
- reporting redundancy as a value determined by the count.
A non-transitory computer readable medium having stored thereon sequences of instruction including instructions that will cause a processor to:
- model in a computer a location having plural racks of equipment to be cooled by a plurality of coolers;
- for each rack:
- compute a fraction of the rack's airflow handled by a cooler;
- sort by magnitude over the plurality of coolers one or more computed fractions including each computed fraction of the rack's airflow handled by a cooler;
- compute a surplus cooling factor;
- multiply at least one of the one or more computed fractions by the surplus cooling factor to generate a modified computed fraction;
- compute a sum by adding the one or more modified computed fractions from smallest to largest until a cooling index for the rack is adequate, while keeping a count of coolers whose modified computed fractions are not included in the sum;
- and
- report redundancy as a value determined by the count.
