Analysis of effect of transient events on temperature in a data center
First Claim
1. A computer-implemented method for evaluating cooling performance of equipment in a data center, the equipment including a plurality of equipment racks and at least one cooling provider, the method comprising:
- receiving data related to types of equipment and an arrangement of equipment in the data center;
determining first parameters related to airflow and parameters related to temperature in the data center at a first period in time, the first parameters related to airflow including a fraction of airflow from a rack which is captured by a cooling source and a fraction of the rack'"'"'s inlet airflow which originated from the cooling source;
receiving a description of a transient event affecting one of airflow and temperature in the data center and occurring at a second time subsequent to the first period in time, the transient event including failure of the at least one cooling provider;
breaking a second time period subsequent to the second time into a plurality of time intervals;
determining second parameters related to airflow in the data center during one of the plurality of time intervals, the second parameters related to airflow including the fraction of airflow from the rack which is captured by the cooling source and the fraction of the rack'"'"'s inlet airflow which originated from the cooling source;
determining the parameters related to temperature in the data center at each of the plurality of time intervals based on the second parameters related to airflow;
storing, on a storage device, a representation of the parameters related to temperature in the at least a portion of the data center during the second time period; and
one of controlling one or more computer room air conditioners (CRACs) to adjust airflow in the data center and controlling one or more equipment racks in the data center to reduce power based on the determined second parameters related to airflow if the airflow is not adequate to provide sufficient cooling.

Abstract
A computer-implemented method for evaluating cooling performance of equipment in a data center. In one aspect, the method comprises receiving data related to equipment in the data center, determining first parameters related to airflow and temperature in the data center at a first period in time, receiving a description of a transient event affecting one of airflow and temperature in the data center at a second time, breaking a second time period subsequent to the second time into a plurality of time intervals, determining second parameters related to airflow in the data center during one of the time intervals, determining the parameters related to temperature in the data center at each of the time intervals based on the second parameters related to airflow, and storing, on a storage device, a representation of the parameters related to temperature in the data center during the second time period.
