Scope
Introduction OVERVIEW OF THIS BOOK Today's datacom (data and communications) facility managers and operators understand the importance of protecting their business' critical data and information technology (IT) equipment (or datacom equipment)@ which includes servers as well as storage@ communications@ and networking equipment. Data center operators must therefore implement standards and practices for ensuring the integrity and functionality of the equipment within the datacom environment. High-performance data center facilities accommodate a variety of complex and sensitive datacom equipment that is vulnerable to internal and external sources of shock and vibration. Shock and vibration sources are unwanted forces found at some level in most datacom facilities that over time can degrade both facilities and equipment. The datacom equipment and infrastructure equipment can themselves be vibration sources within the data center. Datacom equipment manufacturers can control these vibration sources by reducing the internal vibrations that are transmitted to the surroundings. External sources such as airports@ trains@ nearby mining operations (quarry blasting)@ construction activities@ and earthquake and weather events are other sources of operational shock and vibration. These shock and vibration sources are transferred through the building structure to the data center and finally to any operating server and supporting infrastructure equipment. The effect of these disturbances on the function of the IT and telecommunications equipment depends on the design or the robustness of the equipment itself. The best practice to reduce and circumvent the potential disruptive effects of these shock and vibration sources is to eliminate@ minimize@ and control the input shock and vibration levels. The best place to manage shock and vibration is at the originating source@ which may not always be possible
