I've seen the SYBA SY-PEX40008, but would prefer to have a PCI-e 4x
connector for the bandwidth and avoid a port multiplier if possible.
Since this will be in a ZFS pool, I'd prefer not to have 1 bad port take
out more than 1 disk. :) I have seen the Sil3124 chipset mentioned
before in my searches and wasn't sure of its level of support either so
it's nice to know that chipset is well supported. Does the siis driver
support offlining and swapping hard disks without rebooting?
The Adaptec 1430SA seems to use a Marvell chipset according to some
searching of the freebsd archives:
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2005-10/0389.html
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2005-11/0441.html
http://old.nabble.com/Adaptec-1405-on-FreeBSD-td26337538.html
But Adaptec's own site/documentation doesn't want to confirm it for me.
The best I've come up with is:
http://ask.adaptec.com/scripts/adaptec_tic.cfg/php.exe/enduser/std_adp.php?p_faqid=12177&p_created=1098385883&p_sid=1tiW_K3k&p_accessibility=0&p_redirect=&p_lva=438&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PWRmbHQ6MSZwX2dyaWRzb3J0PSZwX3Jvd19jbnQ9MjE5LDIxOSZwX3Byb2RzPTQ1JnBfY2F0cz0mcF9wdj0xLjQ1JnBfY3Y9JnBfc2VhcmNoX3R5cGU9YW5zd2Vycy5zZWFyY2hfbmwmcF9wYWdlPTE*&p_li=&p_topview=1
I've found a commit that mentions support for the 1430SA:
http://lists.freebsd.org/pipermail/svn-src-stable-8/2009-November/000565.html
But I'm not sure what the state of the support is or how stable it is
with that driver (looks to be ata?)
If the 1430SA uses the Marvell chipset (as it appears to), then I guess
the question comes down to the level of support for the Marvell 88SX6541
and 88SX7042 chipsets.
Anyone know the current state of functionality for the above Marvell
chipsets?

I've been trying to find a PCI-e SATA II (300MB/s) controller card for
a FreeBSD 8.0 system, but am having problems determining if FreeBSD
8.0 will support them. Ideally I'd like to find one that is not a HW
Raid controller, as I don't need that functionality since I place to
use ZFS and the HW Raid on the card just gets in the way. I know that
a HighPoint RocketRAID 23x0 (2310, 2320) will work with the htprr
driver, but those are HW RAID cards.
I've found 'Adaptec 2241000-R 1430SA' and 'Rosewill RC-218' cards, and
those are the ones I'm having a hard time telling if FreeBSD supports.
Searching of the e-mail archives has given me mixed results and
nothing definitive to say that they work.
I'm not sure what chipset the Adaptec 2241000-R 1430SA uses, but the
Rosewill uses the Marvell 88SX7042 chipset. I'd prefer to use Adaptec
if possible as in the past they produced good SCSI boards and used to
be well supported (in Linux anyway), but I'll use the Rosewill if it's
well supported in FreeBSD. It's also possible Adaptec has taken a hit
in support/quality since I last used one of their boards. :)
I think the Marvell SATA chipset work is still a work-in-progress. It
may still be supported by the ata(4) driver, but that driver typically
does not support any SATA-specific features, such as NCQ.
Does anyone know if the above boards are supported in FreeBSD? Anyone
have any recommendations for PCI-e 4x SATA controllers with a minimum
of 4 internal connectors?
We use a handful of the SYBA SY-PEX40008 cards
(http://www.newegg.com/Product/Product.aspx?Item=N82E16816124027) to
manage a handful of drives with ZFS. The cards have some RAID features,
but you can simply plug disks in and use them without involving the RAID
layer. If your motherboard supports it, you can even disable the Option
ROM from showing up on boot.
Overall, the performance has been pretty good. The siis(4) driver has
full support for the Sil3124 chipset that these use and supports all of
the bells & whistles like NCQ and FIS-based switching for port
multipliers. They have also been very stable. The only gripe for me is
that it's only 1x PCI-E, instead of 4x, so you won't get full
performance out of it once you have 4 fast drives attached.
