I'm just curious if anyone knows how the minimum usable capacity is calculated for an array. For example, on their website, a 72TB(12x6TB) raw disk capacity array's minimum usable capacity is 50TB. I know Nimble uses RAID-3P which is triple parity with no dedicated spare, I feel like this way the minimum capacity should be bigger than RAID6 with spare which has 72-(6x3)=54TB minimum capacity.
