Thank you Barry:
Here’s another topic I often get asked about. Things used to be quite simple and I covered this for many years in my Configuring for Optimal Performance series of technical university presentations (also here on the blog – parts 1, 2, 3) – and the basics are still the same when configuring RAID arrays, but now with DRAID, people are asking if this still applies. In general the same rules and concepts apply, but you may have to adjust some of the thinking, particularly when you are configuring large DRAID arrays behind an SVC system.
Enjoy your reading.
