DTrace and ZFS are both available on FreeBSD.

Call me a BSD bigot (even though I use Linux/OS X at work) but I really fail to see any rational reason to use Solaris at this point.

We have a Solaris database + filestore at work, mostly for Z-raid, but now that FreeBSD has ZFS, when it gets EOL'd (with a vicious grin on my face) it's going to be a BSD box that replaces it.
