I have a Mac Pro with the Sonnet E4p card which gives me 4 esata ports. What it looks like I may need is 6 ports. Does anyone have experience with using a port multiplier and is there one that could be recommended for use with a Mac Pro. I cannot use up another pcie slot. I'm taking out a Sil3132 2 port raid controller so that I can install a video input card with hdmi. Again TIA.
