Chapter 2. Planning and Architecture
Choosing the right RAID solution can be a daunting task. Buzzwords and marketing often cloud administrators’ understanding of RAID technology.

But unfortunately, deadlines and financial considerations can make any mistakes catastrophic. I hope that this book, and this chapter in particular, will leave you informed enough to make as few mistakes as possible, so you can maximize both your time and the resources you have at your disposal. This chapter will help you pick the best RAID solution by first selecting which RAID level to use and then focusing on the following areas:
Hardware costs
Scalability
