Hi all.

I'm one of those people who search cost-effective storage solution.
Now we can buy a SATA enclusure kit(*1) only for $200 which can be a
400GBx4=1.6TB storage connecting with just a single eSATA cable. It's
very attractive for me.

     *1 http://www.kuroutoshikou.com/products/etc/gw3.5x4-s2_fsfset.html
     (written in Japanese)

But it uses SATA(II?) port multiplier capability and as a SATA
controller chips it requires Silicon Image 3124(PCI-X) or 3132(PCI
Express) support for OSes.

FreeBSD's ata(4) tells me that currently supported Silicon Image chips
are 3112/3114, and google and cvs repository say nothing about SATA
port multiplier capability support on FreeBSD.

Does anyone know current status and future plan about SiI 3124/3132
and SATA port multiplier capability support?  

Thanks.
