There are only two channels so you can only have 2 drives in raid 1 or 0. Don't use 0 unless you don't care about your data.
You didn't specify the type of motherboard or SATA RAID chipset, but all of those onboard RAID controllers are not true hardware raid (Host raid) and require special software drivers in the OS. You are much better off purchasing a separate hardware raid controller such as the 3Ware 8006-2LP 2 port, 3Ware 9500S-4LP 4 port, Adaptec 2410SA 4-port controllers. They do true hardware raid and work with FreeBSD.
Hope that answers your question.
Unfortunately ... yup :) I was hoping to avoid the extra cost, but glad to have it confirmed ... thanks ...
BTW, the motherboard/chassis is the Intel SR1400/SE7520JR2 ... which, re-looking at the specs negates the original question anyway :) it only holds 3 drives ...
Thanks though ...
Wait, now I'm a bit nervous, as this is the first time I use SATA on anything but a desktop ... so my experiences are limited to 'single drive' systems ...
The 8006-2LP ... how many drives will that support? Just 2, right? And the 9500-4LP will support 4? So, is it one cable that goes from the controller card to the chassis SATA backplane?
From reading their web site, multiple "cable" would be the MI cards,
instead of the regular ones ... right?
