Data center design

The process of building a data-center facility appears to be simple on the inception, but there are several aspects that must be done correctly. Get started with these excerpts from Chapter 4, 'Data Center Design,' of the book Administering Data Centers: Servers, Storage, and Voice over IP by Kailash Jayaswal.

Chapter 4 Introduction

"A coach is someone who tells you what you don't want to hear, who has you see what you don't want to see, so you can be who you have always known you could be." (Tom Landry)

This chapter discusses guidelines for building a data-center facility. The process appears to be simple on the inception but has several aspects that must be done correctly. "If you cannot get it right the first time, learn your lessons and aim again" is a great motivator, but data-center architecture and construction must be done right from the get-go. Modifications and retrofitting a data center would involve ripping up floors, walls, HVAC, and electricity, and that is very difficult, expensive, and cumbersome.

An important distinction must be made between the data center itself and contents within the data center. The data center is the physical site, facility, the raised floor, UPS (which kicks in if power from the utility company fails), power generators (if installed to provide power for extended blackouts), network infrastructure (Internet connection, routers, switches, terminal servers), and air-conditioning units. On the other hand, the contents include servers, data storage subsystems, and shared monitors (if required). Both the data center and the contents are important. Without the contents, the data center is a big, expensive, cold room. Without the data center, the servers have no power or connection and are nothing but expensive boat anchors.
