Just get something with the processor and memory you want and get an IBM M1015 off ebay or where ever to handle the drives.yomisei posted:The ability for ECC in Intel chips comes from their integrated memory controller and therefore only the Xeons (and new server based atoms like the S1200) can do this. I'm not really sure about what chipset the MB needs to be, but I think it is irrelevant as long as it mounts a Xeon. I *think* they all take ECC but some need unbuffered and some need registered.

There are extra signals that need to be routed to support ECC, but a board intended for the above CPUs will generally take care of this for you. There's also BIOS support required, but again if it's designed for a Xeon, it would be the utter epitome of  to leave it out of the BIOS. Old high-end eVGA boards I think would route the ECC signals regardless so whether you loaded a Xeon or a i7-9xx, you could have ECC.

crm posted:The reviews on NewEgg list a LOT of DOA/quick failures for Every Hard Drive Ever Made This isn't exactly a new thing, hard drives have a high rate of 'infant mortality' - if a drive is going to break in the warranty period, it's probably going to break very early on. All the more reason to make sure part of your process with a new build / new array is a burn-in period to try to identify any drives that will fail.

People who get duds tend to be the most vocal and brand polarized, you can't really trust Newegg reviews unless there is a clear pattern or consensus. The WD Red drives are excellent but pricey unless you get them on sale. I went with some Seagate 3TBs for my latest build and while they are a tad noisier the performance has been great. My fileserver is headless and sits in a closet anyways so it didn't really matter. If I could've gotten the WD Reds for $90 like the Seagates then I would've been all over that.

The Seagate Barracuda 3TB are consuming about twice the power of a WD Red, also getting quite a bit hotter by that account. If you run them constantly for a few years their price difference vanishes in the electric bill. Their more silent operation is also more reassuring than the occasional cirp by the Seagates.

Eh the reds were literally double the price up here in Canada and the 3W difference (only at load) isn't amortized in a year or two. In terms of temps mine are running at low 30s in a Fractal R4 with the default single 140mm intake. I have no doubt that the reds are better drives and they would have been my first choice but I have parity + backups and the differences were too minor for me to care. I'll see how their reliability is in the long term though, maybe that will make me change my mind later on.

Figure an average of 2W more from the Seagate, x 6 drives x 24 hours/day x 365 days/year = 105KWh/year @ $0.08/KWh = $8.40/year more for the Seagates. Even at current Amazon prices of $834 vs $894 it'll be 7.15 years before the Reds pull ahead. 4.77 years if the drives are fully loaded 24/7, at which point failure rates play into it a lot more than power costs. And if you got your Barracudas on black friday for $90... forget about it.

Replying to my own post because I discovered that this does exist. It's the Portwell WADE-8011. These are not sold through retail channels and are not sold individually. The only sales info I could find was a group buy by an Australian forum where the final price was around $200/ea. shipped. If there is some interest besides myself I wonder if a group buy on the US side could be started.

For 6 drives there's an adapter but I forget the name. The PSU isn't that powerful though, I don't know if I'd trust it to run 6 drives but people have reported success. You'll also want 8 or 16 gigs of memory (I bought Kingston ECC).

Can you run hardware RAID 5 on those N40L boxes? Or do you have to add in extra hardware? edit: ok apparently you need to add a card. It seems with all the extra stuff you have to do to fit those 6 drives in that it's a better idea to just build your own custom box. Am I wrong? crm fucked around with this message at 17:02 on Dec 15, 2012 |

Most people using a N36L or N40L are using software raid such as zfs. The extra work to use 6 drives instead of 4 is to spend a few bucks on an esata -> sata cable and a little bracket to fit two 3.5" drives in a 5.25" bay. This is significantly cheaper, albeit not as flexible, as a DIY NAS.

As to whether it's a good idea or not to run 6 drives on a N40L vice a DIY NAS, it really depends on what else you've got in your list of requirements. The N40L is effective, cheap, and small. However it doesn't have any room for future expansion, is limited on ports (wouldn't be great as a HTPC), and has mediocre performance compared to more full-fledged solutions. If you just want a box to store some stuff on, though, it's really hard to top.

You can run any of a variety of Solarix setups, FreeBSD, etc. By far the most popular are FreeNAS and NAS4Free, which both offer plug-and-play setup, built-in applications for the most popular tasks (BitTorrent, CFIS, FTP, etc), and a decent web-based GUI so you can run the entire thing headless.

Comradephate posted:I can't seem to find anything more recent than early 2011. I have nothing but utter, complete hatred for mdadm right now. mdadm silently switched my metatdata from 0.9 to 1.2, utterly loving my LVM groups. Tried to restore the LVM metadata, but seems like everything is still mis-aligned. I had to go into hexedit and manually hunt down superblocks and try to dd them to a different drive to recover files  That rant aside (my Friday  ), apparently thanks to LLNL ZFS on Linux is pretty slick; I don't know if I'll switch having gotten used to the in-kernel CIFS server + using NFSv4 ACLs for access control, but nice to see the option there.

Comradephate posted:I can't seem to find anything more recent than early 2011. I imagine ZFS is significantly slower at some tasks (since it performs checksuming of all (meta-)data) and faster at others (resilvering only allocated space). The fact that the filesystem, RAID, and volume management are all united would probably save you time, though.

I somehow had completely missed LLNL and was just looking at FUSE. Between that less-than-glowing anecdote about mdadm and my desire to gently caress around with ZFS, I think I'll give it a shot. Thanks!

Oh, mdadm usually doesn't cause that many problems and is generally a pretty good solution. I was just really angry because I blew a workday trying to unfuck the cesspool of mdadm + LVM + ext4 because it had about as much documentation as your average FOSS project and as a result fell behind on a customer release But more converts to the cult of ZFS is always good

Semi silly question. I'm buying an antec case and 8 drives to make a freeNAS RAIDZ3 array. Is it smarter to use 2 5in3 ICY Dock bays to fit these, or just put them in the case without the ICY DOck bays? I know people have mentioned the backplanes won't fail, but if they do they can wipe out 5 drives with them. Do people recommend docks over no docks? I've alluded to this concern before, the bays have gotten not so great reviews on newegg

The ONLY reason for you to be using a 5-in-3 with a backplane is because you HAVE TO in order to fit the drives in, or because that's the only way to get some other feature (like hot-swapping). If you can do it without any dock bays, do it that way--it's the easiest and the cheapest. If you can't, but could get by with a 4-in-3 without a backplane, do that, instead. Cheap backplanes are only asking for trouble.

I was planning on switching my N40L over from Ubuntu/ZFS to Windows 8/Storage Spaces, but if I can stick to Win7/Raid5 I'd probably be happier with that. I've got no plans to upgrade the capacity of the pool (it's 4x2tb ==6tb with redundancy at the moment), just hadn't realised you could do software RAID in Windows. I guess the performance is better than Storage Spaces too?

You can throw a bunch of different size disks at it, *magic* happens, and you get a storage pool that both offers redundancy makes the most efficient use of the disks. (It's not really magic, of course, but how it's carving things up behind the scenes is hidden from you. The BeyondRAID section in that wiki article I linked does a good job of explaining how a Drobo might handle different size disks. I'm assuming Storage Spaces works in a similar way.)
