THis mobo only has 3 SATA III ports. Do you have to purchase a raid controller? Too bad it doesnt have onboard video.

I built my own NAS for around 1000 USD (converting from JPY) and that INCLUDED four 3 TB WD Red drives. My case is slightly under 400 mm with seven hot swap bays and a 5" drive bay, plus some internals and the Synology is 340 mm with eight hot swaps, so there's not a huge difference in size either. If you don't mind doing it yourself and configuring things in FreeNAS, it's cost-effective.

SATA2 is more than enough for HDDs as only SSDs can utilize the bandwidth of a SATA3 interface. In my attempt to switch from 4x3TB Seagate Barracuda XT to 4x3TB WD Reds I managed to put them all onto my ASRock MB (with a little help of my desktop PSU and Molex->Sata power adapters) and managed to copy the whole volume over with 90MB/s. The Intel Pentium P2120 has integrated graphics, which works totally fine with the MB's video connections. In today's time no MB has integrated GPUs anymore, it's in the CPU now. Finding a proper case is probably the biggest part of building your custom NAS, as there is little variation in low cost internal parts to chose from. Plus all the joy unpacking and sticking things together ![]() yomisei fucked around with this message at 01:07 on Jan 15, 2013 |

Good cases: - Fractal Design R2/3/4: 8 hdd bays for $100. + 5-in-3 = 13 drives for $10.75 per drive. - Fractal Design XL: 10 hdd bays for $140. + 5-in-3 = 15 drives for $12 per drive - NZXT Source 210: 8 hdd bays for $40. + 5-in-3 = 13 drives for $6.15 per drive. - Rosewill RSV-L4500: 15 hdd bays for $130. No expansion. - Silverstone Kublai KL04: 9 hdd bays for $120. + 5-in-3 = 14 drives for $10.71 per drive. - Azza Helios 910: 4 hdd bays for $80. + 3x 5-in-3 = 15 drives for $13.33 per drive. - Xigmatek Elysium: 8 hdd bays for $165. + 4x 5-in-3 = 20 drives for $16.20 per drive. - Xigmatek Elysium: 8 hdd bays for $165. + 2x 5-in-3 = 18 drives for $13.55 per drive.

I dont care about putting the system together I build computers all the time. How much many should I get? What about CPU? Id like to go intel. I assume an i5 1155? I have access to any OS so its no cost to me. Should I still go with freenas or possibly windows server 2008?

FreeNAS does ZFS and runs off a USB drive, which is why I chose it over something Windows. I went with an i3 3220 for lower power. I've been using the NAS pretty steadily and it hardly ever pops over 60%.

Sorry. Typo. How much memory should i put in system?

I put in 16 GB because I found a nice sale but it's probably way too much given the load I'm seeing. I'd probably have been fine with 8 GB or even 4 GB, honestly.

My only concern is that I want to be streaming 3d Bluray ISOS which are 50gigs. This MB have a good nik card? http://www.newegg.com/Product/Produ...N82E16813157329 Its got 3x Sata 3 and 5x Sata 2. Can I raid all eight at once? any performance issues with controller on MB?

Yes, you can use all of the SATA ports for RAIDZ. Are you going to use any PCI cards or 5" drives? I thought you said you built computers all the time?

I dont plan on using any PCI cards or 5" drives. I wasnt sure if you needed to put an aftermarket nik card or raid card. I am hoping the performance of the onboard ones are fine?

Try with your onboard one, see how it works out. If it doesn't do so well, get an Intel NIC. 400W should be more than enough.

Any MB you know that have a good intel nik out of the box? Does freenas allow you put different size drives in like SHR on the synology or do they have to be the same size?

It's NIC, not nik. Look at motherboard specs. http://www.cod3r.com/2010/04/zfs-on...nt-sized-disks/

The RTL8111E chip on the ASRock board is fine, I get 95MB/s on FreeNAS with it, and I'm using an Intel 82579 NIC on my Win7 desktop. The F version does have some bandwidth problems though due to being connected only via PCI. As for the rest, I already gave you a recommendation of RAM size and PSUs to chose from. Depending on your frugality you can pick a Pentium P630T, P2120 or an i3 3*** CPU, but they're mostly the same in performance and more than enough (~15-25% cpu) to stream at 100MB/s over GBit-Lan. One thing to keep in mind is that this system will run at 25-50W, so a well rated low power PSU is always worth the investment. Efficiencies at 5-10% load tend to vary strongly between 65% and 80% in different models. There's also the PicoPSU option, but that doesn't work out well with scalability and a bunch of 3.5" HDDs.

So I have a Freecom Silverstore set up as Raid1 with 2 2.5TB drives. Yesterday, after rebooting it, I noticed that I couldn't connect to it anymore via AFP and the config page shows it's entirely empty. There were several dozens of gigs of data on it, though (luckily nothing vital, we're using it mainly as a way to share family photo's and video's so everyone's still got their original files). I ran a filesystem check and a bad block check, but still nothing's showing up. What could've caused this, and is it possible to recoup the data?

You can use ZFS on different sized HDDs, but only the lowest capacity will be available to the pool. One thing to keep in mind is that ZFS can't be upgraded on the run by adding more drives, instead one common way is to replace one drive at a time with a higher capacity and resilver it. After replacing the last lowest capacity one you'll have a bigger pool available.

After replacing the last lowest capacity one you'll have a bigger pool available. So if I start off with three 3TB drives I cant just add another one to the array? That sucks. I was planning on starting with three drives and adding more when I got the $$$. I was planning on having 8 3TB drives total.

You can expand the pool, but not the individual array - if you bought another three 3TB drives, you could add a second 6TB RAIDZ device to the pool, with the downside being that you're effectively taking the space hit equivalent to RAIDZ2 but only RAIDZ levels of redundancy. Linux / mdadm supports growing arrays, but doesn't have a lot of the features that are pushing a lot of us over to ZFS (for me, it's the data scrubbing).

I've got a 20 bay Norco case, and I really like it. I'm in the process of beginning a rollout to a bit more storage. Currently I've got a 2 port sas raid card, I like it. I want to run more drives, and I'm happy with my current throughput. Will one of these work to expand out to more drives: http://www.newegg.ca/Product/Produc...E16816117207CVF sorry for the really stupid question, but I haven't really had any background with larger arrays or anything outside of the logical side of things..

I believe that is just an expansion card which essentially allows you to connect it to an actual raid controller card to increase the number of drives your raid card can access. Basically you still need some sort of hardware controller compatible with the expansion card for it to do anything.

What's the ZFS OS of choice at the moment? It will be virtualized, if that matters. Linux + ZFS-on-Linux v0.6.0rcxxx? BSD still? OpenSolaris/Indiana? All it has to do is expose shares over an internal VMnet.

What's different between traditional raid and ZFS/btrfs is that they do data integrity checks with every read which makes reads potentially slower than a "classic" raid5/6 implementation but you should never be returned invalid data, just potentially no data. I assume raid5 data scrubbing is basically useless because you can't tell if the error is in the XOR or the actual data, a part of the classic "write hole" problem for raid5. You can always just use raid6 to begin with and not have this issue. A UPS will solve the other major part of the write hole problem, stripe inconsistencies due to power failure, leaving only faulty disks/controllers which can honestly screw over a ZFS/btrfs file system just as much.

I am thinking of getting a HP N40L to set up my very first NAS. One problem that I have is that the location of the NAS will not be close to an Ethernet port so I will have to go wireless. Running wires is not an option unfortunatly. I am not really worried about speed as I will only use it to stream simple DVD and CD rips over DLNA to my TV. What are some options to add wireless to the HP N40L? Can I just get a USB Wireless adapter like this one http://dx.com/p/mini-portable-usb-8...er-black-103696 Is there a special trick to get Wireless adapters operating in Linux based OSes like Open Media Vault? Many thanks! Edit: I'll look into Powerline adapters; thanks everyone. JasH fucked around with this message at 07:45 on Jan 16, 2013 |

Since you will need to plug in the power somewhere, would lan over powerline adapters be an option?

JasH posted:I am thinking of getting a HP N40L to set up my very first NAS. Thought about trying powerline adapters ? A bit more expensive but generally a far better option for most people. If you can find somewhere to buy them with a decent return policy so you can try them out first (their performance can vary depending on wiring) I would definitely try that first (if the cost difference isn't a big deal).

Regarding powerline adapaters, in all my experiences with them, I'd recommend doing 200/500Mb versions or don't bother. Actual speeds are never what they advertise, and I typically see 10-20% of advertised speed with them. In theory 20Mb is plenty for anything except uncompressed BR streams.

I need a new internal hard drive, but for some reason it seems like external hard drives have some better deals at the moment. I'm guessing that I should be able to take apart one of these external enclosures and steal the HD out of it? I don't really have a problem destroying the enclosure if necessary.

I'm a complete newbie when it comes to stuff like this, so I'll probably sound dumb. Basically, my iTunes library is getting too big and I'd like to shunt it onto a NAS. First off, is that possible, i. e. will iTunes recognize a NAS as a legitimate music source? As for devices, I was thinking of the Synology DS112+ with a 1TB HDD. Is this a decent NAS?
