Are you using a box with AES-NI instructions or just plain ZFS (without encryption)? That's one of the reasons I'm still undecided. With FreeBSD, I could set up swap on a dedicated slice/mirror without going through ZFS/GELI; which is important on older CPUs that don't have AES-NI instructions. I'm quite afraid of the performance hit if swap is on ZFS/GELI.

I just booted a server with a USB key containing the FreeNAS image, and it works like a charm. Maybe something similar would be possible with plain vanilla FreeBSD; will have to investigate. > So its more then just a GUI. > Indeed. > However they do not have a well defined or a defined for that matter, > roadmap. > Yup, that's the other concern I have with FreeNAS. The most important question would be: would FreeNAS ZFS/GELI volumes be importable into a regular FreeBSD system, should I decide to switch back to FreeBSD (e.g. if FreeNAS ceases to be supported/updated sometimes)? I suppose yes, provided the keys are properly backed up, but without testing, I wouldn't bet the farm on it. Thanks, -cpghost. -- Cordula's Web. http://www.cordula.ws/
