But in the article http://www.sqlservercentral.com/articles/FCI/92196

the SQL FCI ( Node3 and Node4) does not have identical filepaths as the Node1 and Node2 which are standalone

The SQL FCI is installed on G:, H: and L:

How does this demonstrate the Microsoft recommendation of having identical filepath ?

I am looking at implementing this architecture but with both the SQL FCI and the standalone instances using the same drive letters .

Any pointers would be much appreciated?
