Hi Matt, Thanks for the suggestion about the RAM disk. I set up a 1GB ramdisk on the target machine today and mounted it from the initiator. Did a dd on it for roughly 900MB (The computer itself only has 2GB RAM, so I figured this *should* be an OK test size) and got over 300MB/sec to it. As I had rebooted, the frame size was only 1500, not 8000 (woops), so it was possibly slower than it should have been as well, but I guess that means it is probably the disks/controller.
Well, my question now is, "What does that mean now?" I'm upgrading the controller firmware this morning (burning an update CD right now), but what's the next step? I thought of putting a couple of drives on the motherboard controller for some testing to eliminate the SAS controller, what do you reckon? All thoughts/advice appreciated (and thanks so far!)
