I just saw an interesting article on Computerworld.com "A tale of two U.S. government data center projects" where one project came in on-time and within budget and one went over budget and was late. The moral from the story is that the project that went over budget used the Design-Bid-Build (traditional bid/spec) approach and the one that came in on-time and within budget opted for a design/build approach – where you have a single point of contact and that contact is very familiar with the project from the start and can make any necessary changes fairly quick. Many times, as in the case of the over budget project, when a problem arises you have to negotiate with multiple teams to get things fixed which more often than not results in delays.
There are a few important questions that facility and data center managers need to ask themselves to make sure they are on the right track in terms of timely and proper computer room air conditioning (CRAC) equipment maintenance; these include: What maintenance needs to be done on the equipment? When? How often?
