So the way this works is that the system has a 24-slot disk backplane. The disks plug into the backplane; you have to connect the backplane as a unit to something, which is where the HBA comes in. It doesn't look like there's a way to wire an individual drive to an onboard SATA port. (The boot drives are in a separate rear caddy and connect direct to the motherboard.) Aside from the drives, this is supposed to be a fairly standard Nexenta-compatible system. We're just running OmniOS rather than Nexenta on it. -- -Peter Tribble http://www.petertribble.co.uk/ - http://ptribble.blogspot.com/
