Data centre forecasting is not for the faint hearted. Let’s say a company decides to increase its data centre capacity. Generally you have a lot of different inputs into the decision making process; IT, facilities, Data centre operations, procurement, CIO, CFO, executive board. Each of these roles has a different focus and nobody wants to get such a significant capital investment wrong. Rightly, they want to ensure the capital is wisely spent and will suit their needs long into the future, after all changing your mind after the fact is expensive and risky! So rather than forecasting the foreseeable future (2-5 years) they need to somehow forecast for 10-15 years.
