BUILD Need help with 20TB+ NAS system which can be expandable in need

Same price? First one all the way! It's newer, which is better.

Well, after a week I learned a lot of stuff.
I didn't want to open a new post so here is my hard choice:

Setup 1
Chasis = SC847E16-R1K28LPB
MoBo = X10SRI-F
CPU = E5-2620V3
RAM = 4x 8GB DDR4 2133Mhz 1.2V ECC REG
Controller = LSI SAS 9207-8i

Of the two choices I'd pick Setup 1, but I'd also consider something like the Supermicro E1CR36L. It's probably going to cost less than buying a separate chassis, motherboard and controller, and it will also have all the cable routing, motherboard installation, etc., already done. Just add CPU and memory.

The E1CR36L comes with an X10DRi motherboard, similar to the X10SRI but it also includes an onboard 12Gb/s LSI 3008 SAS/SATA controller. The 9207 is a 6Gb/s card.

One thing you would need to do is flash the 3008 to IT (HBA) mode. It's not that difficult--I've done it myself and there are lots of how-tos floating around. I believe by default the E1CR36L's controller is set to IR (RAID) mode, which you would not want to use with a ZFS filesystem.

The LSI 3008 is supported in FreeBSD 9.3 and newer so it ought to work out of the box on FreeNAS 9.3.

irreplaceable, irrecoverable and extremely important data.

Still I'm willing to take the risks for "1 in a Million" chance failures.

Even if it is a secure system when planned right, you could loose all the data at once. What about the case of fire, burglary, ...?

I think this one is the "1 in a Million chance" kind of thing :D

These two REALLY REALY REALLY don't go together. SERIOUSLY suggesting that you reconsider.

There is an important engineering principle that says that something very unlikely will happen if the outcome of it happening is particularly bad. Some Irish engineer discovered this law.

I remember it.. I can't remeber the name of it. This is gonna drive me crazy...

Murphy's law

Murphy's law.. LOL!

No, there is some real engineering law out there that says something about "the worse the result, the more likely it is statistically, despite all information that may be contrary". There's been a paper or two written about it in the last year or something. It has to do with the more you try to engineer out something, the more likely you are to accidentally cause it.

Sounds like the experiments with infinite improbability--the engineers didn't realize that anything that was infinitely improbable was in fact almost certain to happen nearly immediately. Except that that was a figment of Douglas Adams' imagination...

The chance of a falling piece of buttered toast landing buttered side down is directly proprotional to the cost of the carpet.
