I need to setup a NAS server to hold my family's pictures, movies, music, network shares etc.
Not only that it will also be used as a Owncloud jail, so I can synchronize school work, documents etc. Over multiple computers.
Specs: Intel Pentium G3220 ASRock E3C226D2I, ITX server board, 1150 socket with ECC support. 2x Kingson ValueRAM ECC, 4 GB sticks, 1600 Mhz. 4x WD Red, 3 TB disks. Fractal Design node 304 case. Cooler Master b500, 6 sata power ports for expansion.
I was planning on using RAID Z2, for more redundancy. Not only that It will backup every day at 2 AM to an external fireproof drive just in case of fire, and later off site.
Tell me what you think, can this fully utilize the 1 Gbit nic and allow in-home bluray streaming?
If you are going to have multiple people connected to the NAS at the same time using CIFS shares on windows then you'll need a CPU with more cores/threads or you could have some performance drops. The G3220 would be fine in most single use cases but it's only a dual core so having multiple users could slow the performance. More cores at a lower frequency and power draw would be optimal. Something like ASRock mini-ITX board with Intel Avoton C2750 Octa-Core. I swapped to a 35 w i3-4130t after using a G3220 for a few weeks. You'll also need to double the RAM. 8 GB is the minimum but you should have at least 1 GB of RAM for every TB of raw storage space for the best performance so 16 GB would be better with this storage configuration.
Edit: My FreeNAS config is in my profile description.
If you want to use RAIDZ2, they say you should have 1GB memory per 1TB of raw storage. While you have enough, I would still suggest doubling your RAM. get 16GB in there.
This will get you started. I don't know what back ground you have in networking, but be aware that you'll need a smart network switch that supports Link Aggregation Control Protocol in order to link multiple NIC's to increase bandwidth. The cheapest 8 ports run about $80. The 8 GB of RAM will be enough to get you up and running but you'll probably not be able to saturate a 1 Gib link. ZFS file system loves RAM, the more you can give it the better it will perform so plan on buying some more memory later.
I went through a few configurations before I settle on the one I have now. My 6 disc RaidZ2 array transfers at around 85 MB/s on windows share, while 4 disc array in Raid 1+0 consistently saturates the gigabit link at 110 MB/s. I also use a 60 gb SSD for jails. I took it out of my desktop when I upgrade it. I run Plex, transmission, subsonic, firefly, a murmur server for mumble, and Unbound DNS Naming service. Plex loads a little quicker running off the SSD than the main array but I do loose the redundancy if the SSD fails.
Build completed, temps are decent at about 50 idle. Personally I would like to see it lower, but only a fan inside the case pointing at the motherboard could fix that.
