Regarding this specifically:
Attached storage devices refer to the total number of storage devices you are allowed to have connected to the server before starting the array, not counting the USB Flash boot device.
What if I start my array with only 7 drives but plan on adding 5 more down the road, am I still covered?
Also, when I am at 12 drives and say I want to swap 1 or several out with larger capacity, am I still covered under the 12 limit since I’m not actually exceeding 12 drives?
