Can anyone help me clear the below confusion:
When we model/size the capacity in STORM(Storage modeller Tool), the maximum available array grouping is 14+P+Q (Plus 1 x Hot Spare added by default). That is total no of drives will be 17.
There are 2 queries arise here in my mind:
(For Storage GUI)
If we size with 14+P+Q +1 x hot spare by default, the storage modeller shows the capacity as below:
But if we configure with 14+P+Q the storage modeller shows the capacity as below, how it calculated this capacity:
AN EARLY RESPONSE WILL HIGHLY APPRECIATED.. Thanks in advance

Thank you explaining the capacity concepts on DRAID. Actually I am aware of these facts that you have explained. What I am confused is totally on storage modeller capacity outputs wrt the number of drives when it is exceeded than 17 and available grouping in STORM is max 14+P+Q.
Take this as as a use case that if we need to configure 24 FCM drives then what array grouping we will use as best practices as we have max 14+P+Q. And if we take it then how the storage modeler calculate the capacity what is the formula behind.
The whole point is when the drives are below 18 we can explain the customer the grouping as depicted in storage modeler capacity out put but as it exceeds 17(i.e. 18 or greater ) then customer ask what is the disk distribution and how it is calculated. So we must have any solid formula to explain. Attached below is the screenshot of such example.
