Eliminating external air infiltration in edge containers

A computer program product, the computer program product comprising a non-transitory tangible storage device having program code embodied therewith, the program code executable by a processor of a computer to perform a method, the method comprising:

• determining a fan speed for one or more air conditioning unit (ACU) fans and storing the fan speeds to a computer memory for later recall in response to detecting a request for authorized entrance to a modular data center;
• adjusting the one or more ACU fans in preparation to deploying one or more retractable baffles that, when deployed, form a temporary vestibule within a space of the modular data center;
• deploying the one or more retractable baffles to form the temporary vestibule within the space of the modular data center, thereby shielding computing resources in the modular data center from contaminant air that enters the temporary vestibule when the external door is open;
• unlocking the external door to allow entry to the temporary vestibule;
• detecting the entry into the temporary vestibule and closure of the external door;
• purging the contaminant air from the temporary vestibule;
• retracting the one or more retractable baffles, exposing computing resources in the modular data center to the space used for the temporary vestibule;
• and
• restoring the one or more ACU fans to the one or more fan speeds from the computer memory.

A computer system, comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
• determining a fan speed for one or more air conditioning unit (ACU) fans and storing the fan speeds to a computer memory for later recall in response to detecting a request for authorized entrance to a modular data center;
• adjusting the one or more ACU fans in preparation to deploying one or more retractable baffles that, when deployed, form a temporary vestibule within a space of the modular data center;
• deploying the one or more retractable baffles to form the temporary vestibule within the space of the modular data center, thereby shielding computing resources in the modular data center from contaminant air that enters the temporary vestibule when the external door is open;
• unlocking the external door to allow entry to the temporary vestibule;
• detecting the entry into the temporary vestibule and closure of the external door;
• purging the contaminant air from the temporary vestibule;
• retracting the one or more retractable baffles, exposing computing resources in the modular data center to the space used for the temporary vestibule;
• and
• restoring the one or more ACU fans to the one or more fan speeds from the computer memory.
