I have a brand new DL380 G5 with both SATA (factory fit) and SAS
(add-on) controllers. The drive backplane is connected to the controller
with two data cables. How is it wired internally? Can I mix SAS and SATA
on the same backplane, connecting the left part of the backplane to the
SAS and the right part to the SATA controller?

If not: what is the purpose of the two data cables? They can't actually
run into the same bus on the backplane, can they?

cheers
Heimo
