There are edge cases where non-ecc ram is ok with zfs... like if you
aren't storing data there. My lab functional test system doesn't
have ecc, my systems with my company data all have ecc. Test
systems, or any place that has an entire copy of the exact same
data, possibly in HPC. I have a customer that has rows(8 systems) of
the exact same set of 100's of TB of data, but even then they use
ecc. Just a mess to clean up later. So lab, functional test system
to me is the only place it's ok. It is america though :)<br>
<br>
If non-ecc'ed ram passes zfs an inaccurate block.. It can be laid
into the pool as bad metadata and make the whole pool unreadable. A
couple bucks more for ecc ram and you have all your data!!<br>

<div>Thanks. My main box also has an AMD CPU, as it was the most
cost effective way to get ECC RAM. Hmmm -- speaking of which,
I'd be interested in your and Linda's thoughts on the necessity
of ECC when using ZFS. </div>

My FreeBSD box has an AMD CPU and support for AMD's SVM just
landed in the<br>
development branch a couple weeks ago, so I have not had a
chance to really use<br>
it. I will talk a bit about it, but I can't do a demo, sorry.
If the bhyve AMD<br>
patch gets MFC'd into 10-STABLE before the meeting, I will
upgrade to it and<br>
play with bhyve a bit after the presentation, but it will be
my first time<br>
really getting into it.<br>
