Hey guys,
I'm looking at changing the configuration I was planning on my new NAS setup due to some concerns with the way I was going to do it. One thing I want is for my NAS to be low powered, and produce little heat. The new c2550 and c2750 atom chips look very appealing for this. I'm looking in particular at this board: http://www.supermicro.com/products/motherboard/Atom/X10/A1SAM-2550F.cfm
It has a lot of nice features for a server board and can be gotten fairly cheap (saw one site with it for 250). I could also get it as a barebones system on newegg for 550, but not sure if I'd go that route because it's only a 4 bay chassis and I want at least 8 bays.
I'm concerned though with the compatibility of everything on this board. Especially the NICs, I'm not familiar with that NIC they are using on this model at all. It's listed on that page as:
So the first question is if anyone has any experience with this board or these NICs and know if FreeNAS will work on it? And is FreeNAS going to be able to do Link Aggregation on 4 NICs?
Next question is concerning memory. I obviously will get ECC memory, but I'm wondering if 8GB will be sufficient, or if I should go with 16 GB? My array will most likely be consisting of 8 x 4tb drives (I already have the drives I just am not sure if I will put all 8 toward the NAS or not). If 8GB is sufficient, is there any real advantage for free nas to use two sticks instead of 1? I was considering if I did 8 for now, I'd do it with just 1 stick so that if I did decide to upgrade later I could still potentially put it up to 32 GB without having to replace smaller sticks.
Next is about the performance if I'm planning to run just FreeNAS and a Plex media server on here. From all reports I've read these little atom chips actually perform really well. With a quad core 2.4 ghz for this model do you guys think performance is going to be adequate with potentially up to 8x 4TB encrypted disks?
The last question I have isn't relating directly to that board but a question on the best disk configuration. I've been doing a lot of reading today about potential problems and it seems like even raid 6 (raidz2) is somewhat risky with drives of this size. But I can't really think of any other raid configuration that would be any less risky. Raid 5 has the worries of a single drive failing during a rebuild, raid 6 of 2 drives failing (while a lower chance than a single drive it is still a somewhat significant number according to what I've read, in the neighborhood of a 6 to 10% chance). A raid10 type configuration could be equally risky and it really depends on where a 2nd drive failed if one were to fail in the rebuild. If it failed on the same mirror as the first then no big deal, but if it failed on the other mirror then you have a problem lol :) So what raid configuration is considered safest these days for higher capacity disks?
Thanks for any information you guys can give me :)
