What is the best recommendation as far disk configuration is concerned by Microsoft for building exchange 2003 cluster (6+2) active\Passive. I read some whitepaper\technet documents in which it discusses different scenarios:- 1) Have log folder as mount point and exchange database as drive letters. 2) Have log folder assigned to individual SG as drive letter and then have exchange database as mount point. Concerns :- Considering i want to build 6+2 cluster i cannot have 4 drive letters assigned per node starting from E:\ or else i will run out of drive letters and the maximum nodes I can have is 5. Please advise for the best solution as the only solution i have in mind is to have single drive letter per node which will represent Log and Exchange databases as mount point.
