12 Finally, the 'failure-finding' task may make it possible to test the item at a practical interval that reduces the probability of a "multiple failure" to a tolerable level. This involves a statistically proven methodology employing reliability data to establish a practical interval, particularly for failures involving safety and environmental consequences. For consequences with operational a n d n o n - o p e ra t i o n a l c o n s e q u e n c e s , t h e methodology employs cost criteria for optimizing the interval. This is particularly instrumental for informed decision making of intervals for standby generator systems, redundant cooling units and associated infrastructure components. For IT systems, consider analyzing critical path communication device MTBF (mean time between failures) and evaluate spare parts or replacement devices along with fail-over plans. All too often many systems designed to operate as standby (cold) redundant are actually operated as parallel (hot) redundant. Operation in this manner results in a reduced system reliability as it introduces excessive wear on redundant components. The RCM process demonstrates there can be proactive tasks identified to maximize system reliability where redundant components are treated as designed and maximum life-cycle management is realized. In short, RCM identifies the 'safe-minimum' work necessary to assure sustainable safe and economical operation of all data center assets. Moreover, in the era of demand for high availability and lower energy consumption it would benefit operators to review design drawings, validate operating context and ensure redundant systems are optimized regarding operation, testing and maintenance. These are completed under a RCM analysis. Failure-finding task interval analysis aids in eliminating legacy intervals which allows all stakeholders the opportunity to employ reliability data for particular equipment and make informed decisions on proactive maintenance task, as well as optimizing those tasks for greater maintenance cost effectiveness. Conclusion The time is now for a paradigm shift by senior managers to engage RCM. It is ideal, if not critical, given the demand for reliable data centers. The RCM paradigm is a distinct set of concepts and methods that constitutes legitimate contributions to the entire data center environment allowing, all stakeholders to realize a reliability-based culture and thought process. The 50+ years of airline industry implementation of RCM has demonstrated this method's rigor and success in reducing and eliminating failure consequences of complex systems. RCM is employed by few operators of MEP system within data centers, but those who have implemented it benefit f ro m i m p rove d ava i l a b i l i t y. Th e co m p l ex structure of IT systems will benefit from the rigorous analysis process of RCM for enhancing change management techniques. The support infrastructure of MEP systems will realize improved reliability and availability by nature of optimized maintenance procedures, accurate spares analysis and a thorough vetting of the operating context to ensure capabilities. A holistic engagement of IT and MEP system through an RCM analysis enhances site-wide reliability and high availability. The data center industry has experienced a substantive maturation process around design and commissioning; RCM implementation embraces the long term role of operating and maintaining assets. Finally, the RCM process will deliver documented operating and maintenance procedures around a detailed operating context for the operators of the asset, and is a transferrable body of knowledge for future operators, thereby demonstrating a sustainable business practice.
