For a business whose mission is dependent on effective information and communications technology - such as data centers and call centers - expansion or relocation raises many questions with respect to a facility's electromechanical systems. As these businesses are keenly aware, a critical failure can significantly compromise financial performance. The most frequent cause of failure of critical systems is power disruption, followed by mechanical system problems and human error.
When assessing a site for expansion or relocation, owners must first understand the risk of a critical system failure and its potential cost to business performance. A risk assessment and feasibility study should be performed to identify these risks and costs, and compare them with the cost of effectively managing the risk at the required level of reliability at a particular site.
The feasibility study should analyze the business' anticipated growth over a period of time and determine whether the local utility structure can meet its needs. In many areas of the country, the power demand created by the exponential growth of data centers is exceeding the capacity of the infrastructure.
The study should also assess whether the site can be configured to meet current power and HVAC requirements, and whether it is flexible for future adaptations of the infrastructure to keep pace with business growth.
When critical systems fail, the cause is most often power disruption - either outright power loss or inadequate quality. Data and call centers use some combination of multiple power feeds, facility-wide generation systems and localized backup systems to provide a reliable power source in the event of loss.
For example, some owners demand two power feeds into the building from different sectors of the power grid to ensure continuation of base power. Others require a single power feed to the site, with building-wide backup generation capability to avoid a catastrophic failure. Localized UPS systems can provide additional protection to critical areas of the building.
Some developers are building business parks specifically for call and data centers, featuring higher reliability power grids in the development. In some cases they are offering an on-site co-generation plant to supply tenants.
Even if a building never loses power, unstable voltage levels or other distortions will cause disruptions or failures of critical elements of telecommunications and information systems. For example, a nearby industrial plant that drops off power causes fluctuations in the power grid, and those fluctuations will spread across the network.
Today's call and data centers also require far more complex mechanical systems to avoid the second most common cause of failures in critical telecommunications and information technology - inadequate cooling and/or humidity control.
Another major cause of failure in data centers is human error in the maintenance and operation of electromechanical systems. The more critical data centers require two plant operators there at all times to provide a check and balance.
The fact is, electromechanical systems for data and call centers today are not only mission-critical, but exceedingly complex. Owners must consider all the issues and seek out the right resources - those with the extensive risk and site assessment, design, installation and maintenance expertise to assure the levels of reliability business performance requires.
