A data center is an infrastructure in constant motion; it will always be necessary to remove, replace, or add new equipment, which implies changes in the network cabling infrastructure, power, changes in electrical consumption, heat generation, etc.
How do we keep the data center infrastructure operating at peak efficiency?
Measurements
What gets measured gets managed. It is essential to have data showing how the data processing center is operating, from power consumption and PUE to temperature measurements at strategic points, etc.
In recent years, we have seen how various DCIM software manufacturers have developed truly useful products for Data Center management. This allows for proper administration while maintaining high operational efficiency in the Data Center.
Simulations
CFD (Computational Fluid Dynamics) is a tool that allows modeling and simulating the behavior of the data processing center. In an early design phase, it enables the implementation of a more efficient solution. CFD software is also useful for optimizing the operation of a Data Center that is already in production, whether to resolve existing issues or to evaluate where and how new equipment should be installed.
Cabling System Documentation
The data cabling system is a vital part of a Data Center. We have often seen how an inappropriate design can cause cooling or airflow problems in the Data Center, especially when cooling and cabling share space under the Raised Floor. Maintaining an organized and documented Cabling System allows technicians to perform their tasks faster and more easily, without cabling growing out of control.
Keep Your Data Center as Clean as Possible
One of the worst enemies of computing equipment is dust; it has been proven to be an electrical conductor. If a layer of dust accumulates on an equipment’s electronic board, over time it can cause short circuits leading to total or partial damage.
Dust generally enters the Data Center on people’s shoes. It is useful to place a Contamination Control Mat or use disposable shoe covers.
Cleaning the Data Center at least every six months is of utmost importance, using the proper equipment to ensure dust removal.
Hot or Cold Aisle Containment
Hot and/or cold aisle containment is an excellent way to increase efficiency in the Data Center. This solution seeks to boost Data Center efficiency by ensuring an optimal Delta T between cold aisle and hot aisle air, as well as concentrating cold air only where needed. Using these techniques, we can also increase the AC Set Point up to 80.6°F [27°C], according to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), which results in a significant reduction in Data Center energy consumption.
Preventive Maintenance
Preventive maintenance of equipment is vital to ensure each unit operates optimally, minimizes the risk of failure, and anticipates future problems when performed periodically.
Each piece of equipment has a maintenance plan recommended by its manufacturer. It is necessary to maintain precise control to ensure that all maintenance is completed according to these recommendations.
Maintenance Contracts
For the peace of mind of Data Center managers, it is always recommended to have warranty extensions or technical support directly or indirectly from the manufacturer. A failure in a mission-critical environment must always be addressed urgently to restore normal operations; if failures are due to a defective part, it will be essential to replace it as quickly as possible without stopping Data Center operations.
Simulated Tests Under Controlled Environments for Power Outages
Power outages, regardless of their magnitude, frequency, and duration, are highly probable. By conducting controlled tests, the backup system—whether UPS, ATS, or electrical generator—can be evaluated. This guarantees or minimizes the risk of potential issues halting Data Center operations in the event of a power failure.
Fire Detection and Suppression System Testing
Although a fire affecting the Data Center is unlikely, the fire detection and suppression system is an essential solution, as a fire puts company information at risk. The system must be tested in controlled environments to guarantee optimal performance and ensure that, in the event of an incident, it responds correctly as designed.
