It doesn't look like there is one available yet. To use the same Marvell chip, there would have to be a PCIe to PCI-X bridge. Another option that I haven't seen discussed is to use a card based on the SiI3132 PCIe chip (1x to 2 Port SATA300) combined with a Sil3726 port multiplier. You could hang 10 drives off of the single card, though you'd have almost twice the total bandwidth (2000Mb/s vs. 1067 Mb/s), but potentially less per drive than an AOC-SAT2-MV8 in a PCI slot. For an inexpensive home NAS, this should be OK, but it depends on use patterns. Since ZFS does checksum calculations on the host, the PCI or PCIe interface should wind up being the bottleneck in both cases. -B _______________________________________________ opensolaris-discuss mailing list [email protected]
