Some how I can not edit my original post - to insert the images that I promise.

So I have to post in a new post (sorry for the confusing, if any).

Here they are:
32TB in 4U 20Bay rack mount NAS consumes less the 200W
Front

Back


430W Power Supply - More than 100% overrated


Raid controllers connect connect direct to Motherboard SATA ports


WD Green HDD - consume only 6W during R/W


Currently use for streaming BD.ISO multiple TV

This is the 1st time i post of how to build, i may missing lots of info
if you have question PM me of post here

Hmm! Strange I can not edit the old post

Well here is the transfer result with my 40TB raw FreeNAS runs with 4x SPM394 + SuperMicro ITX Board+2Gb DD2+ 20x WD Green 2.0TB - Using single Gb E port



Update 8/2012
Here is the transfer speed of Teaming 2x Gb E to SSD

Hi guys!

I've started this thread because i wanted a cheap solution for my data storage problem, but i didn't found a cheap solution with an easy setup-function AND easy administration. So i went to some low cost NAS but sold them some days after getting them, they didn't sattisfied me.

Two weeks ago MediaMarkt (a great german consumer electronic retailer) launched a campaign with the slogan "We sell 1000 products to the price we bought them!" and *surprisesurprise* they got a HP DataVault X312 for little less then 350 € in the shop. Two weeks before that campaign i bought two cheap 2 Tb Seagate HDDs for storing some TV series and make backup of my PC, but didn't do it in time. So the two drives lay around in our bedroom (my "office" since we got our daughter ). Oh, the PC and the X312 are conected with an Netgear GS 108 GE gigabit switch.

But back to the HP DataVault X312! Here are some informations about the device:

X310 (US model), X311 (european modell)
Operating System: Windows Home Server
Processor: Intel Atom D510 Dual Core 1.66GHz
RAM: 2GB
Storage: 1TB (1 x 1TB)
HDD-Bays: 4
USB Ports: 4
eSATA: 1, with port multiplier support!
Networking: 1 x Gigabit Ethernet Port
Warranty: 2 Years in germany

The X312 is simillar to the X311 but with 2 Tb of storage (build with two Seagate 1Tb HDDs).

The setup was done realy fast, the client software was easy to handle and the whole OS settings were done in around 10 minutes but ... why are there only so few settings??? And the first file copy tests didn't show me an im pressive increase (40 - 50 Mbyte / sercond for hunge MKVs and 30 - 40 Mbyte / second for small AVIs) to all these cheap HDD enclosures i owned before. But i smelled that there was a little bit more potential in the air!

A short research on the internet explained that this "clear" GUI is for the entry users. And there is a magic word called "AddIn", which can solve ALL problems very easy. So i installed the AddIns "WHS Advanced Admin Console" + "LightsOut" + "FileManager". The most important AddIn ist WHS Advanced Admin Console where you can change everything like on an normal OS. So i did a small tweak and activated Jumbo Frames 9k on my PC and my X312 and ...
*TATA*
Huge MKVs = 84 - 87 Mbyte / second
Small AVIs = 73 - 75 Mbyte / second
*TATA*
That's the way i wanted it all the time!

So the next step would be to buy a Lian Li EX-50B and a 5 2Tb-HDDs to get ALL my MKVs in the home network. With this little box i got aroud 14 Tb of storage space which is plenty enough for the next year!

i flashed openwrt on my tplink 703 and have been happily using it as a NAS。

Here's the link to my unRaid server! It works great. I can stream to four different locations at the same time without any issues.

I love your project. Perfect IMHO, as it is what I'm about to do? The only thing I am confused about is the SAS backplane connectors. I've see pics of what they are, but besides that, I haven't a clue about them.

How are the cables connected to the HDD / backplane / sas end?
As in what sort of cables were used?

A photo or two would be nice, please

Thanks
Fred

Norco has most cases in 2 versions :

With sata backplanes with traditional sata connectors (4 per backplane), so you don't need special cables but there will be a whole bunch of them!
Or sata backplanes with 1 SSF8087 connector per backplane where you need only 1 special cable which connects 4 drives.

If needed there are also cables which go from SFF8087 to sata!

hmmm, ok? !
So basically (my brain of thinking way) I go from.....

motherboard SATA port --> Port Multiplier (link port)
-
PM (4ports) [Mini SAS to 4x SATA Breakout Cable] --> backplane
-
backplane to 4x SATA HDD's
Correct ????

I am assuming that I cant get a rackmount 4U server chassis with just HDD holders (no backplane !), Norco or other brand?

As I want to RAID the HDD's, does this mean I am limited to the PM Equipment configuration, ie I can only have a 4x HDD raid 5 ???

Another Q. Does a 4 port SAS Controller mean I can only have 4xHDD connected as in only 1 cable as mentioned above?
or is it 4 ports as in 4 cables totaling 16xHDD ?
just to clarify.

FYI&Q. I have already have a case and HDD built, but I have already filled it to capacity.
I already have 2 PM cards with total of 9xHDD's.
I am trying to decide to keep going down the road of PM's, or switch to other technology, like thunderbolt or internal SAS Controllers.
I want to keep costs down, and have something with RAID 5, 50, JBOD, or similar as to keep the number of "visible" drives to a minimum. I don't mind sacrificing transfer speed for cost. I do however want an all in one box, not a bunch of external HDD holders like http://www.hotway.com.tw/products/h82-su3s2.htm

Thanks

Yes there will be twenty of SATA cable comes back to SPM394(s)
If you have a traditional SATA backplane then group them as five drive per top-down column
top -down fashion 1/2/3/4/5 COL1 go to the 1st SPM394 http://www.datoptic.com/esata-hardwa...er-spm394.html
and ...
top -down fashion 1/2/3/4/5 COL2 to the 2nd
top -down fashion 1/2/3/4/5 COL3 ...
top -down fashion 1/2/3/4/5 COL4

If you have SAS back plane, then you should have 5x SAS cable like this:
http://www.datoptic.com/29-inch-inte...7-cable-1.html

Assume top downs 1st SAS cable as S1, 2nd row SAS cable as S2, ...SAS3 as S3, SAS4 as S4, SAS5 as S5
Then the 1st SPM394 connect to S1-1, S2-1, S3-1, S4-1, S5-1, that are the drives from the 1st column, do the same with 2nd, 3rd and 4th column

I hope this explain it
