Hello.
In my search for a SAS controller, I've been offered an Adaptec ASR3405
or ASR3805. These are not supported in 6.2R, but it looks like they will
be in upcoming 6.3R by the aac driver.
I'd like to know about ground experiences with these cards. Do they work
well? Does aaccli allow for production-time online check and array rebuild?
Any trouble?
bye & Thanks

We use the Adaptec 3805 here at Juniper with great success. The 3805 and
15K SAS drives are damn fast. We are very happy with them, however there
are a few caveat.
* The Adaptec driver in FreeBSD 6.2 does not understand what a 3805 is.
Adaptec has released an update to the driver in source code. It is on
their web site. There are several people who work at Juniper who have
the commit bit so we are going to try and get the updated driver into
the tree before 6.3.
In the mean time, in order to install 6.2 with a 3805 one needs to
install the driver at install time off of a floppy or a USB driver. Then
either copy the kernel driver into /boot/kernel or recompile the kernel
with the new driver. It's a little bit of a pain but once it's you can
forget about it.
* The early versions of this card had a nasty bug in the firmware. When
the card was put under a heavy load the card would stall and timeout.
Adaptec has released an update to the firmware on their web site. The
update is a bootable ISO image. Updating the firmware requires one to
reboot the system with the bootable CD then updating the firmware using
the supplied program.
* Aaccli, which is in the ports tree, does not understand what a 3805
is. Adaptec has a replacement program on their web site but I have only
played around with it and not spent a lot of time with this tool. I
would guess that it has all the same functionality that aaccli had.
