I would like to hear if anyone is using ZFS with this card and how you set
it up, and what, if any, issues you've had with that set up.
However I would expect that if you could present 8 raid0 luns to
the host then that should be at least a decent config to start
using for ZFS.
I can confirm that we are doing that here (with 3 drives) and it's
been fine for almost a year now.
I've accomplished that with a similar RAID card, set each drive to a 'JBOD' mode
in the RAID BIOS, this properly presents individual devices to the OS so ZFS can
do it's thing. One thing to note however is that if you remove a drive and
reboot without replacing it the names of devices may be shifted forward a number
causing havoc with a ZFS pool.
Additionally, depending on the OS be, careful with attaching removable storage
on bootup as this may also shift the names of the devices -- I've personally
experienced it on FreeBSD 7.1 with a USB stick attached during reboot. The
stick happened to take the name of my first drive on this RAID device.
