Any idea about the FreeBSD support for Adaptec 1405 (ASC-1405)?
I doubt. It is more SAS then SATA card.
As far as I can say, SAS controler are SATA compliant.
In this particular case, the description from Adaptec reads "Cost-
effective I/O supporting SATA and SAS". That's fine, if I can upgrade
to SAS HDs later, it's a cool feature.
Any PCIe card suggestion is appreciated.
FreeBSD 6.x is already legacy. If you are building something new, you
should look forward.
I know, but 8 is not ready, and I don't see the point in upgrading to
7. And more importantly, I own a second server, hosted in a
datacenter: I try to keep OS version synchronised, so that I can test
buildkernel/buildworld/install on my local computer before trying the
update on the (very) distant server.
What I have tested:
- SiI3124-based - fast and functional. It is actually PCI-X one, but
there are many boards with built-in PCIe bridges.
- two SiI3132-based (Adaptec 1420SA and many others) - as cheap PCIe
x1
alternative (max 150MB/s per card). These two better supported with
new
siis(4) driver on 8.0, but should work on 7.x with ata(4), haven't
looked lower.
- First generation of SiI chips (SiI3114). They are quite old - SATA1
and PCI, but they are long-time supported and they take all possible
from PCI bus, and in 66MHz PCI-X slot can give even more. But I have
heard some negative comments about them.
- Supermicro SAT2-MV8 on Marvell - recently tested it on 8.0,
supported
in 7.x and probably before. Adaptec 1420SA is from the same series.
But
they are PCI-X (tested it in PCI).
- Adaptec 1430SA - PCIe, based on newer Marvell chip. Added basic
support recently to 8-STABLE. Not supported before.
- most of chipset-integrated controllers (Intel, NVidia) are really
not
bad when working in AHCI mode (they are not limited by bus speed).
- JMicron-based PCIe x1 adapters. They are cheap, AHCI-compatible and
not so bad, but limited by bus speed at about 180MB/s per card.
PCI-x and PCI are not an option for me.
In fact, everything comes from the fact my system behaves strangely
from time to time.
Long explanation here:
http://lists.freebsd.org/pipermail/freebsd-hardware/2007-June/004541.html
This problem disappeared for a long time, but came back just today. My
wifi card is PCI, and according to the motherboard setup, PCI bus is
on the same controller as on board SATA (with PCI-X too). The only
slots that sit on a different chip are the two PCIe. I think that if I
could move my HDs on the PCIe buses, it might resolve my problem. Even
if it does solve this issue, it'll give me SATA II, in replacement of
SATA I motherboard connectors. Either way, I win :)
