Partition at the MSA level. Not the OS level. Dynamic disks are not supported for clustering. How did you arrive at 16 drive letters? You'll need 2 for Data, 2 for Logs, and 1 for Quorum and 1 for Backup. Also, it's 4 primary partitions per disk.

Is it better to partition the drives at the MSA level into multiple small arrays, or should I create two arrays (1 for each cluster node) and partition with Disk Manager? In the end, I need 16 drive letters. If I go with Disk Manager, I can only have 4 primary partitions so I will have to create an extended partition and use volumes.
