File Server Builder's Guide
by Zach Throckmorton on September 4, 2011 3:30 PM ESTAs motherboard layout is important in ensuring that airflow is as unobstructed as possible, case design is also critical in facilitating excellent airflow. If you're building a system with one or two hard drives, most cases work fine for a home file server - just make sure there is a fan near the hard drive(s) so it is not sitting in stagnant air. However, if your server requires multiple disks, here are a few cases that work especially well for file servers.
Mini-ITX
Fractal's Array R2 is a nearly perfect home file server case. At less than 14" deep by 10" wide by 8" tall, it occupies little volume. It positions a removable hard drive cage immediately behind a quiet yet powerful 140mm intake fan. The hard drive cage accommodates up to six hard drives using vibration-dampening silicone mounts, and there is also room for a 2.5" drive (either an SSD or HDD). According to my testing, when stuffed with six low-rpm 2TB mass storage HDDs and one SSD (with an Intel Pentium G620 CPU installed), the temperatures of the HDDs hover around 40C even when all drives are under artificial sustained load (using Iometer). The PSU is a custom SFX form factor model, 80+ efficiency 300W unit with ample amps on the split 12V rail to power six HDDs. The PSU features seven SATA connectors and one legacy molex connector, so there are no extraneous molex plugs and enough SATA plugs. Furthermore, the cables are shorter than typical, so excessive cabling does not interfere with airflow. The case itself is constructed of aluminum so it is lightweight, and its overall build quality is very high. It does not have room for an optical drive, but I consider optical drives superfluous for a home file server. If necessary, you can always hook up a USB interface external optical drive. The only drawback of this case and its PSU is the price: at just under $200, it is not cheap. However, the subjective aesthetics, objective functionality of the case and the custom PSU are worth the cost if you want a small but capacious home file server case.
Micro-ATX
As I prefer home file servers that take up as little space as possible, Silverstone's TJ08B-E is a great, smaller micro-ATX minitower. It's less than 16" deep, 9" wide, 15" tall and weighs less than 12 pounds. It can accommodate up to five HDDs plus one SSD. As with the Fractal Array R2, the hard drives are placed immediately behind a front intake fan - though in this case, it's an even larger 180mm unit. The TJ08B-E is flexible in that it can hold a couple optical drives as well as a GPU in case you want to repurpose or multipurpose it. When stuffed with four low-rpm green drives, the temperatures under load don't exceed 45C during sustained transfers. Overall build quality is very good, like most Silverstone cases.
Silverstone makes a diminutive, fully modular PSU that makes working with smaller cases like the TJ08B-E, Lian Li PC-Q08, and others much easier. Silverstone also offers a short cable kit, making the ST50F-P PSU even better suited to SFF cases. Finally, it's clear that Silverstone had smaller multi-HDD systems in mind when designing the CP06 SATA power plug extension cable. This extender connects to a single SATA power plug and then has four SATA power plugs that are spaced closer than usual together, further reducing cable clutter. Though the cost of these accessories adds up, they make an ideal cabling solution very easy to implement. Regardless of whatever PSU you decide to go with, if you use a split 12V rail model, make sure you don't load up one rail with HDDs. If you go with a single 12V rail model, you'll want that rail to be beefy - for example, don't try to put ten HDDs and four case fans on a budget PSU with a 20A 12V rail.
Full Tower
Very few cases can accommodate ten HDDs at stock (without adding adapters), and such cases are not at all small. Full towers also typically offer excellent airflow, and cable management is not very difficult. Fractal's Define XL is one of the least expensive 10 HDD bay full tower cases available. It is well-built, and extra care has been paid to making the case quiet in the form of panel insulation. It is impossible to hear active HDDs inside this case even when you're sitting just a few feet from it (even the notoriously loud VelociRaptors). Further, there are plenty of integrated niceties like adjustable/flexible cable baffles that assist in cable management. Seven of the ten HDD slots are immediately behind fans, with three slots one cage removed from the front intake fans. Even still, the HDDs that aren't right behind the fans stay cool (between 35C and 40C). At around $150, it is an excellent value. Just make sure you don't pair it up with Silverstone's short cable kit!
We've saved the most important aspect of a home file server - the hard drives - for the next and last component page.

I work with this sort of hardware but have gradually come to the conclusion that this is overly complicated, expensive and utterly pointless at home. In a way it's a bit oldschool in it's thinking.I now use 2 extremely cheap Western digital "my book" live 3TB drives. These cost only $20 or so more than the drive itself and all are more or less full linux machines wrapped around your storage; shell access is easy. These 2 drives simply rsync to each other (or any other PC) for redundancy automatically - in fact they are in different rooms so offer better protection than a RAID array in case of theft, fire etc.. These give about 35MB/s on a gigabit network (that's megabytes) each and therefore cope easily with anything at home.
Best of all they spin down and only draw 2W each (even when operating top out at 12W). The whole system took maybe and hour and a half to set up and has run flawlessly for 6 months. If one fails I can swap it with the same or A.N Other Linux machine.
And what is it discussing RAID performance? What are you guys doing? This is a domestic guide not a datacenter primer. Just how many full-hd streams do you need? I really don't recommend RAID solutions for long term data storage in the home after a decade or so of using them. RAID is about uptime, not data security (OK and in some terms performance).
This was brought how to me when I had to recover some data on an NVRAID array. Basically the only way we could do it was find a secondhand mainboard and build up a whole new PC which was a major PITA. I'd stick to software RAID within the OS at home if you really must use it as it's far easier to recover. It's not like the professional environment with a service contract whereby a man turns up with a NOS new raid card that went out of production 15 years ago and saves the day.
Repeat: RAID is not backup. RAID at home is more often a weakness not a strength.

I think this article falls short of the standard Anandtech level of professionalism I've come to expect. Maybe it wasn't meant to be that in depth. But for me, this is nothing more than a preview to a file server guide.No mention of ECC, no mention of RAID pros/cons, specific RAID hardware, no mention of UPSs and networking technology, no mention of back planes and subsequently no mention of all-5.25" tray cases, no WOL or 24/7 mentioned.
For my taste, this is an okay first look for people who have never put together a computer system. But for everyone else, you just stated what they already knew. Kinda disappointed now. :-( But I hope you will follow this up with more in depth reviews. :D

I thought so too. The content covered is mostly obvious and it seems written for, to put it nicely, a less technically-adept audience. The writing style also seems to be like those lower quality sites that fish for hits instead of providing quality insight.And it's not just this article. A lot of the newer authors don't seem to have the writing capability or insight that the main writers that Anandtech had before. I don't want to name names because most (none?) are clearly as bad as this one, but Anand should pick his writers more carefully. It makes the site's quality look like it's slipping.

maybe Buyer's Guide is better title instead of Builder's Guide.This Guide just tells you what components to buy/use.

The consensus view on the Debian and Ubuntu forums is that Atom is a great home server chip. In the rest of the world, few care because no one wants to learn Linux at home.I understand why you dismissed the overpriced office NAS devices but a heads up should be given regarding the coming deluge of affordable home NAS devices. A home NAS is an end run around the fact that nobody at home wants to learn Linux. It does everything you want using a browser: nobody has to know its Linux. From a software perspective, the overpriced but cute $140 SilverStone DC01 is a precursor of the coming deluge of affordable home NAS devices. ARM and Intel are about to go to war in the home server market and will do anything to be properly positioned to slit the other's throat in a gentlemanly way. Expect free bundled NAS functionality and a better selection of the ports you want as that is what happens in competitive markets. If ARM has it's act together, my expectation is that comparable functionality in a less attractive case will be available for half the money in your choice ARM or Atom platforms within a year. Life is about to get real good in the bottom third of the home server market.

Like he said, NAS is a great and easy way to get storage space for your home system. But they don't offer any good upgrade ability if you need more storage (4 HDD NAS systems are about the highest affordable options, after that, DIY storage becomes cheaper), they often don't offer the best performance (still mostly good enough for HD streaming) and they don't offer anything but storage space. Want to run an email server later? No can do. I have also heard a lot of people say that you shouldn't do RAID with NAS systems.Since this is a file _server_ guide, I think he made the right decision to not go in depth with regards to NAS. He did mention them and told the viewer to read up on them if they never heard about them. Good enough in my book.

Been buying these for a while and they run great. Nice package and surprisingly quiet.http://www.newegg.com/Product/Product.aspx?Item=N8...

One of the best operating systems for a file server is Linux. One of the best Linux distributions currently available is Ubuntu. However, one of the best and easiest to configure file server installations, is Turnkey Linux File Server Appliance http://www.turnkeylinux.org/fileserver.Based on a minimal installation of Ubuntu, Turnkey Linux File server can be up and going in a matter of minutes. Put it on just about any hardware you like and it will ready to serve files. I have seen it work on a virtual machine, an old desktop and server packed with disk drives. Setting up raid is a breeze using Webmin raid configuration and because it is Linux software raid, you are not dependent on a specific controller.
The files can be accessed via Samba, SSH, Web based file manager, or Webmin. Try it! You have nothing to lose.

Just as an example, I picked up a Dell PowerEdge 2900 with dual 4 core CPUs, 16 GB ECC RAM, Perc5i RAID Controller, 10 hot swap drive bays, dual server grade gigabit NICs, redundant PSUs, and Dell Remote Access Controller for remote screen control outside the OS. Total price on eBay was $790 with shipping. I even got 10 36gb 15,000 rpm SAS drives. 4 of those small drives make an OS drive similar in speed to a low end SSD, leaving space for adding 6 2TB drives for RAID5 data storage. I get 110MB/sec file copies, and 250MB/sec transfer speeds within the RAID volumes. Gigabit Ethernet is my bottleneck.It is loud, so you need a basement or place away from people, but you get a lot more for you money than with junky low power consumer parts.
Windows 2008 R2 is what I am using, but most Linux distros would be fully supported as well. I think this will last longer and perform a lot better for similar or lower cost new hardware.
Consumer hardware has always seemed to struggle with heavy disk and network load in my experience, regardless of it's stated specification. Mainboard disk controllers with 6 or 8 sata ports mostly behave like junk if you actually populate all their sata ports.

i thought it was the most widely used NAS raid platform for home users?also the choice of motherboards is quite narrow. what about some supermicro itx boards with 6 sata headers, to me that would be a perfect match for the fractal array r2 case with 6 hard drive slots :)
