The Client is a large-scale wireless communications network provider in the United States that serves more than 5 million customers. Their cellular network consists of Fourth Generation (4G), Long Term Evolution (LTE), and Code Division Multiple Access (CDMA) technologies. The Chicago, Illinois, location functions as the Client’s headquarters and the company also manages four customer care centers located throughout the United States. As an industry leading innovator, this particular Client contacted us due to an increased number of failures within the infrastructure supporting a customer-facing, mission critical application in their Illinois data center. The failures were becoming more noticeable and threatening application service levels.
The Client was reporting an “abnormal number” of hardware failures within a specific set of racks housed in their Data Center. Data regarding the number of failures, frequency, and time of occurrence was inconclusive leading our engineers to believe that environmental factors could be the cause of such an irregularity. Headwaters engineers evaluated two environmental aspects to determine the cause of these failures: Electrical Power System and Space Conditioning.
The electrical power system investigation involved a visual inspection, the recording of sample measurements, a review of the sample readings, and a comparison of the collected information to similar metrics collected during normal operations. For the space conditioning inspections, our engineers performed a visual survey of the air handling units and its settings, sampled temperatures, thermal recordings, temperatures, monitored humidity, and compared resulting data with data under normal conditions for a similar rack. Initial observations and recorded measurements supported excessive heat buildup from the electrical load within the rack as the main cause of the hardware failure issues experienced within this rack.
The Client was facing a complex problem, and their internal team could not pinpoint the root cause. Headwaters experience in this area of Data Center environmental analysis ensured the Client that our engineers had the track record to either diagnose or rule out this problem stemming from an environmental anomaly in this particular data center.
