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? ---- Marc G.
