Method for computing cooling redundancy at the rack level

摘要

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.

1. 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.
