Yes. It works very well.
On amd64 you'll get a pretty reasonable setup out of the box (so to
speak) which will work fine for most purposes.
One other thing comes to mind. I want a very robus, fast rockl solid
*server*
It will be a file- email and webserver mostly.
Instead of using two ZFS mirrors I could also go for gmirror (I'm not
familiar with it, but it's been around for quite some time so it should
be
very stable). I don't get the data integrity that way, but my files would
be
safe, no?
Also, using gmirror I could use "normal" BSD UFS filesystems and normal
swap files devided across all disks?
Or am I wrong, thinking this way.
I'm not into fancy stuff; it has to be robust, fast and safe.
You do not *need* amd64, however it would the best choice. I wouldn't even
mess around with gmirror. It's great and I love it, but it has some
serious
drawback's compared to zfs mirroring. One is there is no integrity
checking, and two is a full resyc is required on an unclean disconnect.

you could add a gjournal layer in there as well for better data integratity.
I think you can do softupdates + journal as well now although I have never
used it
If you're after a rock solid server, then to be brutally honest it is less
important to decide what you run than it is to choose something that you know
well.
Since you have 4 years of Solaris/OpenSolaris experience recently, you are
likely to know ZFS better than gmirror.
So I ask you to ponder - at four o'clock in the morning, with mail down, web
servers down and all the disks holding your files failing to mount - which
file system or disk structure would you prefer to try to troubleshoot?
Dave.
