Yeah i saw some build reviews on freenas, they recommend ecc but it is not mandatory (and actually after reading some tests i don't get all the fuss on ecc ram).
Saw that too and i don't get it, i mean, what the hell? You can replace disks with bigger one but you'll have all this trouble if you want to expand the array? That doesn't feel right. I'm a developper so i might get into a situation where some zfs expertise might come handy, i spend most of my time (10hours + daily even on weekends) on my computer so no problem. Thing is spending 600+$$ on a nas doesn't seem worth it compared to buying an high end raid card. Also it's either having a second case or buying a dual system case which cost more than 500$$, those guys... Spending much money on a raid card also seem like spending money for nothing too as it seems i'll have better performances with hba card + zfs that using a raid card. (did some research meanwhile) If only there was a list of compatibility that would solve my problem, i emailed lsi support but didn't get a response yet, the adaptec card seems a bit pricey for what it is. 2016-02-01 17:16 GMT+01:00 Chris Murphy <li...@colorremedies.com>: > > > On Mon, Feb 1, 2016, 12:32 AM thibaut noah <thibaut.n...@gmail.com> wrote: > >> I'm not gonna use lvm or mdadm. >> I choose zfs. >> I will probably end up buying a little server since i cannot find >> compatible hardware cheaper than an full server... >> > > > http://zfsonlinux.org/faq.html#BasicRequirements > > They recommend 8G RAM minimum, and ECC.
