For Prologis, the growth of its server farm took off and caught them off guard.

After the CRAC failed, the airflow study revealed that the data center's 2,5000-square-feet of raised floor had problems such as holes around pipes coming in and out of the perimeter walls; poor distribution of power; holes in the floor under power distribution units (PDU), and misplaced perforated floor tiles, used to direct air around servers, that were causing a decrease in cool airflow where it was needed most. The study also revealed a hot spot at 95 degrees.

The remediation, which began in early 2008, included a model that showed where critical hot spots would occur if any one of the CRAC units failed. The company also installed blanking panels on their server racks and organized all cabling so heat could be more efficiently dissipated, which reduced rack temperatures 2 to 3 degrees.

Then the perforated floor tiles were removed from the dead spaces where installers had taken the initiative to place them randomly during construction. Holes were sealed around pipes and the holes were closed under PDUs.
