The DL380G5 comes with a "PCI riser" cage that has 3 PCIe slots. There
is an optional "PCI-X/PCI-E Riser" which has 2 PCIx slots and one PCIe.
This would be an option for us and it should work with the 320-2 cards
that we already have. The only problem with this would be that I have
three external arrays with two UW320 ports each therefore I would need
three controller cards.

I have done a search on the PCI-X/PCI-E Riser and, although it has been
discontinued, there does seem to be a reasonable supply available.

I will reconsider the need for all three arrays and see if I can go
with the PCI-X cards.

Thanks for your suggestion.

Regards, Hugh
