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?

SAS = good. SATA = ****e
SAS = server. SATA = PC
SAS = production SATA = test

The only reason for SATA is cost. AND you do not need the performance and
reliability of SCSI (now SAScsi)

I'd expect that the 'add-on' controller is a P400 or a P600. You can still
use both SAS and SATA disks with these (I think), and I reckon that
technically, you can mix them.

From experience, keep to what you're familiar with, set standards and keep
them, and stick to SAS.
