A Modern Pantheon
A modern data center still shares many aspects with ancient architecture, structurally and in service. The form literally
These functional requirements of the data center are:
In the design philosophy of this book, these needs must be met and in the most efficient way possible. The efficiency of the data center system relies entirely on the efficiency of the design. The fundamental principles of a data center philosophy should be your guiding principles.
The phrase "design philosophy" could have many different meanings. For the purposes of this book we'll use the following definition: A design philosophy is the application of structure to the functional requirements of an object based on a reasoned set of values.
Fundamentals of the Philosophy
There are five
Design decisions should always be made with consideration to these values.
Keep the Design as Simple as Possible
A simple data center design is easier to understand and manage. A basic design makes it simple to do the best work and more difficult to do

Design for Flexibility
Part of flexibility is making the design cost-effective. Every design decision has an impact on the budget. Designing a cost effective data center is greatly dependent on the mission of the center. One company might be planning a data center for mission critical applications, another for testing large-scale configurations that will go into a mission critical data center. For the first company, full backup generators to drive the entire electrical load of the data center might be a
Design for Scalability
The design should work equally well for a 2,000, 20,000, or 2,000,000 square
Use a Modular Design
Data centers are highly complex things, and complex things can quickly become unmanageable. Modular design allows you to create highly complex systems from smaller, more manageable building blocks.
These smaller units are more easily defined and can be more easily replicated. They can also be defined by even smaller units, and you can take this to whatever level of granularity necessary to manage the design process. The use of this type of hierarchy has been present in design since antiquity.
Keep Your Sanity
Designing and building a data center can be very stressful. There are many things that can, and will, go wrong. Keep your sense of humor. Find ways to enjoy what you're doing. Using the other four values to evaluate design decisions should make the process easier as they give form, order, and ways to measure the value and sense of the design decisions you're making. Primarily, they help to eliminate as many unknowns as possible, and eliminating the unknowns will make the process much less stressful.
