CM Elite 120 "Pain in the NAS" (ASRockRack/G1840/NH-D14/internal power brick)

[NFSxperts]

My NAS system was previously in the Define R5 case, which was too big.

After another one of the drives started to have reallocated sectors, I decided to downsize to an m-itx case.
I had considered the Fractal Node 304, but the D14 cooler will not be able to fit with 3.5" hdds installed and not all of the drives are oriented the same way.

I'm currently using a Noctua D14 cooler, A SFX PSU, a 5.25 bay fan controller, and using 5 drives in total. 3 in a RAIDZ1 configuration, and 2 in mirrored mode as backup. I'll be dropping the SFX PSU and the 2 mirrored backup drives.
The Elite 120 meets these requirements.

The D14 fits.

The power brick rests inside the case.

Interesting mod to get the power brick to fit within the case!

Yea, I had to remove the front usb i/o to get it to fit.
I can still fit a short pcb 750ti in there.

Well, this really is becoming a pain in the ass.
Previously one of my old disk got reallocated sectors so I decided to start fresh with new disks.
I installed freenas corral, which was released just last month. I have just finished setting it up and now I find out they are canning that project since the lead developer left.
I'm going to start over again with nas4free. Anyone here familiar with that or freebsd in general?

I've been running NAS4Free for years, but I'm not familiar with FreeBSD though.
It's a shame about FreeNAS' issues with the Corral release.

 

[NFSxperts]

Yeah, it really is a shame. Its got a great new interface, and is very easy to setup.

Do you mind if I ask you some setup questions?
I have 3 Toshiba 3TB drives running in raidz1. They are 512e drives so I need to use 4k sectors.

I'm not sure I've set it up properly as I'm getting slower read speeds. (only >700Mbps SMB read speeds while I get 900+ Mbps write) WiIth corral, I was getting 100+ MB/s both read write.

I had to change a few settings with my latest install to get good performance and access on Windows 7, Windows 10 and Linux:

Services > CIFS/SMB > Settings

• Server Max Protocol: SMB3
  
• Server Min Protocol: NT1 (CIFS)
• Client Max Protocol: SMB3
• Client Min Protocol: NT1 (CIFS)
• Send Buffer Size: 131072
• Receive Buffer Size: 131072
  
• Large read/write: Enable
• AIO read size: 4096
  
• AIO write size: 4096
• Asynchronous I/O (AIO): Enable

You might also need to look at system tuning:

System > Advanced Setup

• Tuning: Enable

System > Advanced > sysctl.conf

But I can't really give advice which settings need to be adjusted and how for your particular setup, but you could try and start with these.

 

[NFSxperts]

thanks, I tried your buffer and aio read size settings but it didn't make much difference in transfer speed.
local disk copy speeds seems fine. 300+MB/s read/write.

I switch the disks and added temp sensors

What are you using to read in the temp sensor?

 

[NFSxperts]

Its connected the the lamptron fan controller in the first pic.
Unfortunately its a software

edit: I meant to say unfortunately its not a software.
