AM3+ ECC build

[Lord Crc]

Hi,

I'm new to the world of zfs, but I've done a bit of research and I can appreciate the value of ECC.

As such I'm looking to get an AMD FX 6300 CPU (cheapest one in stock) and put it on this Asus M5A97 R2.0 board. I asked Asus about ECC on that board and they say it's not tested, as such "it may work" but it's unsupported from them.

The manual lists the ECC option in BIOS, which from what I gather should mean the motherboard supports ECC. However does anyone have any experience with this or a similar board?

If it's fairly uncertain if it supports ECC or not, I'd rather shell out a bit more and get a Xeon with definite ECC support.

Any help is appreciated.

what about a good quality supermicro board + something like a pentium g620

G620 supports ecc according to this

or celeron G1620

If you think in ECC, you are thinking in a SOHO or medium enterprise, not a home NAS, so please consider professional boards like b0ssman suggest .

ASUS also have pro boards like some that have "WS" in the name: http://www.asus.com/Search/?SearchKey=%20ws

Supremicro boards are hard to come by here. If I go the Intel route I'll be an Asus WS board.

Thanks for the link confirming that the Ivy Bridge i3's can work with ECC, that's something at least.

where is here?

Norway. I see a couple of webshops have them, but not cheap. As such the Asus WS board looks much more competitive, ASUS P8C WS (C216 chipset) and i3 3220 comes out at about $90 more than the AMD solution.

In my research of zfs, I saw a lot of posts saying ECC was pretty much required to avoid silent corruption with zfs. Are you saying that this isn't so? The report from MS about the frequency of single bit errors in memory wasn't very encouraging.

I could live with a single file getting corrupted, but I'm more worried about the code segments in memory getting corrupted and ruining data over time.

NO.
You can of course buy ECCRAM for your Home NAS.

I say that home NAS are for store data that is not move from disk frequently ( you normally store photos or videos, play one time or two and store for months or for years, this mean that if you have silent data corruption this happens in your disk NOT in your RAM.

In SOHO or Enterprise, by other hands is normally to use DDBB that runs in RAM lots of time, so have much sense to have ECC to avoid corruption in RAM because have data in RAM more time.

Sorrry for my bad english.

Ok, I understand your point. Now that I found that the i3 3320 supports ECC as well, an ECC build looks very attractive anyway, as the price difference isn't very large over a non-ECC build, at least compared to the disks.

Just for the record, I understand silent corruption on disk can be prevented (as much as possible) by scheduling a scrub to run a few times a month, correct?

Thank you both for the replies, and your English is perfectly fine

correct.

one advantage of the supermicro board is IPMI.
Which is a remote desktop over ip but it you can even enter the bios with it.
which is a really nice feature to have for a headless server.

Ah, yes, I can see that being handy. I'll keep that in mind, this first build will be sitting right next to me
