Trying to relate an EMC paper (when it's referencing an Integrated Cache Disk Array) to a JBOD solution is difficult. I can understand your confusion.
If you are using a single controller, I would suggest striping (RAID-0) and using multiple RAID groups (RAID-3 or 5). Separate the RAID groups over the channels. A stripe size of 64K works well with SQL systems.
Note: Even though you have a RAID controller, you only have one, thus a single point of failure.
You can also look at my previous answers where I talk about the optimum way to layout a database.
