Which, to me is great news. Up till now I have been using the excellent Xilinx XUP board however it has one real failing: the ports labelled SATA on the XUP are not capable of talking to SATA devices. They don't support Out Of Band signalling.
The Virtex-5 LXT based ML505 however does support the full SATA specification, as well as a lot of others besides. The reason is more advanced Rocket IO ports.
