Thanks Richard.

I am using active riser to get all the HBAs I need. The passive riser only supports two or three PCI-e slots. In the interest of complete transparency I replaced the active mid plane with the passive mid plane for the drives.

This is actually a tricky wick. I forgot to mention those systems also have DDRdrive X1s. The current configuration is the only configuration that allowed all of the PCI-e cards to work together. The tipping point was adding the Intel 910.  I literally had to create a truth table for all the possible permutations  and test them to find one that worked. Other configurations resulted in missing HBA or other more erratic behavior.
