The smaller the physical space that a server occupies, the faster it will
overheat the environment and cause havoc. Today, building codes (at least in the United
States) define what qualifies as a true data center. There are specific rules about controlling
humidity, minimizing the risk of internal flooding, and maintaining a consistent
temperature. If you walk into a real data center today, you may want to even put on a
sweatshirt.
Even if you have only a handful of servers to manage, being able to maintain the
temperature is crucial to a successful disaster recovery plan.
Hardware and Disaster Categories
Do hardware considerations have an impact on how we look at disaster categories?
Absolutely. The following list shows how the specific hardware issues apply to each
category:
CHAPTER 10 n HARDWARE CONSIDERATIONS 266
??? Environmental:Much of what I??™ve mentioned involves controlling the environment.
Power and heat issues affect every device in your data center.
??? Hardware: This chapter is all about hardware. The question is: do you understand
your hardware components enough to help ensure that your SQL Server data is
insulated from hardware-related issues? This chapter offers a basic overview;
there??™s always more to learn.
