Solid Resources Regarding RAID Technology and Performance
Posted on 2014-08-11
I am attempting to gain much more than a cursory understanding of the features, benefits, and drawbacks of all standard forms of RAID technology (hardware and software) with respect to performance, availability, and integrity. I would include in this an interest in the latest technologies available that provide innovations that look beyond traditional RAID.
I have done quite a bit of basic reading via Google (and some introductory storage text books), but with respect to online blogs in particular, it seems that some engineer will write a specific article stating one thing about RAID (RAID 1, 5, 6, 10, 50, or 60 for instance) and then the flame wars begin on the blog comments with one person claiming that the article is completely wrong, and another claiming that the first two people are completely wrong, and on and on. There seems to be somewhat of a lack of solid and consistent knowledge regarding this important topic in the blogosphere.
So I was hoping some of the experts here might be able to point me toward some excellent free online resources that delve into this topic in depth, even to the point of explaining concepts with mathematical formulas and equations if necessary. I would prefer to have as much information as possible available and then be able to sort out the most critical items and commit them to my knowledge and understanding. I am hoping to shatter some of the uninformed and even ignorant opinions I might have based on misinformation or misunderstandings on my part.
I am not asking for basic articles that explain what RAID is or how it helps by providing fault tolerance and increased performance. I was really hoping there might be some detailed white papers (or even a library of such information) available that dig in deep at a conceptual and technical level and demand the full attention and comprehension on the part of the reader.
I am by no means a storage engineer, but even in more generalized IT, I believe that this is too significant and important a topic for IT professionals to base their decisions on rules of thumb they might have developed 15-20 years ago.
Thanks in advance for any information.
