An Home/Office NAS

Zitat von mat650

What do you think about it? I'm pondering to purchase it. I'm not experienced with it, so...would you support me with the test/reviewing of that MoBo?

Where exactly are you stuck? What are you thoughts?

Mh, not bad. They finally got that under control.

EJ188H (USB controller)= ??

Supported.

Also in the case I will decide to don't use this NAS for “home” use, it could be nice to keep the machine capable of transcoding for the office, Movie are not just for entertainment. Considering the environment, 5 users, working on CAD files, 3d/render files and one or two 1080/720p parallel transcoding, or other media use as opening of extra large pictures,how many GBs of RAM would be recommended ?

The NAS does exactly 0% processing in images, CAD or rendering because it is just sending files through network. For it there is no difference between an image or a 3D file. It's all MB to be read and sent through the ethernet port. NAS life is boring.
I'd say 4 GB ram will be enough.

PSU: some suggestion?

Seasonic S12II-430, I doubt it will need more than 200 watts, but that's as low as I can get without going into the "cheap but total crap" segment of the PSU market, where even if it is genuine Seasonic it is not Seasonic quality.

If you see a PSU you like, check reviews, it should do well in all tests, overloads, voltages and ripple tests.

System disk= is there any issues to install the system on a USB stick? should I look for somethink in particoular? to prevent an accidental removal could be fine to plug the usb stick in an internal usb hub/converter like this?

At the moment it's not a very good idea.
From OMV version 2.0 (currently in testing) you just need to disable some logging options from settings (settings not available in OMV 1.0), and you can safely install on USB drive (decent brand USB drive).
Also yes, internal mount is strongly recommended, the world is full of curious people that love to pull usb drives....
That thing you found is good and simple. Minor correction: it is a USB port with a header connector, it's not a hub/converter.

Storage: Seagate NAS HDD 2TB x3 RAID 5 or WD Red? I dont need a huge ammount of storage and that Seagate has a good prise per TB

can you post the model number here?
Shouldn't matter much, but there are a few models that are on the "don't buy list".

Zitat

How can in my case be convenient to increse the fault tolerance up to two failed drives (RAID6)? €/TB in my case is important.

As long as you have external backups that's fine.

Zitat

ad more... is not dangerous to backup the version on the same array? if i loose the array i lose the backup too..

Versioning is NOT backup. It only prevents accidental deletion from user error.

Zitat

Is not enoght to versioning just the important WIPs on an less expensive 1TB WD green, which I have yet?

important data should be backupped into an external drive (you have USB3.0, no problem).
Then you should pull the USB cable to physically disconnect the drive (and disconnect also the drive's auxiliary power if any).
In this case, even if there is a catastrophic power failure and the NAS dies (thunderstorms, crappy power lines, PSU suffers a meltdown for unknown reasons) the data in the external drive is safe.
It is also convenient in "take the data and run" disaster scenarios. Otherwise you would have to be running around with your NAS.

OMV has another plugin that detects drives and automates these tasks, it is called "Usb Backup". You just need to connect the USB, let it run, disconnect the USB after it has stopped writing (if you have a USB enclosure with write activity leds it is easy to see this).

If your WD green is a big internal drive, just buy a USB 3.0 external enclosure for 3.5'' HDDs for it (20-30 euro tops) and you are fine.

You people... **shrugs** I love black tea but you 2 are on a different level.

yeah, if you have a 110v wall socket for that. Good PSU though.

the hard drive isn't in black list afaik.

Zitat

You must be very patient.

no problem, Just making sure that the point was clear.

Zitat

I have a lot of work in front of me, this time I give up.

You can recycle an older usb hard drive you have around (or buy one new that you will turn into secondary backup after you update the NAS).
An SSD is kinda pointless on a NAS, most of its system is loaded/cached into RAM anyway.
Unless you care about boot-shutdown times anyway.

It is very nice to use a SSD. Very snappy gui and fast boot/shutdown times. I will never use a normal Hard Drive as a boot device. Just my 10 cents.

Good luck and try to give us build pictures.

I usually take into consideration the use case of the device I'm assembling.
A NAS is not going to be rebooted very often, and also the snappyness of the GUI isn't exactly another very important factor, it's something that will be seldom accessed.
Also, even my Zyxel 325v2 has a snappy interface (personal opinion) if the OS is in a Sata drive or on a fast microSD card (on a fast microsd reader). MUCH snappier than its own firmware.

Btw, that thing about the GUI snappyness should be made moot by moving the bulk of the static webserver files to RAM on boot.
Running the whole OMV from a ram-only squashfs + a JFFS partition for settings and minor updates like 99.99% of embedded systems would be pretty cool. But I'm getting carried away...

In general, I'm not against cheap SSDs (that got orders of magnitude cheaper than most DOMs I'm finding), I'm against wasting a Sata connector for the OS drive.
That SSD can be put in an "external" USB enclosure with little performance impact (again assuming you don't run benches on the OS drive).

On my mobos I typically have enough ports. Using RAM is nice but not as reliable. There is a noticeable difference using a SSD vs. a 5400/7200 drive. High quality SSDs have become inexpensive, especially when they are on sale. I got a couple Intel 530 somethings 120gb for about 50 bucks a piece. I've had really good experience with my Intels and Crucials. My current drives are 60gb, or 80gb. With wear leveling and given that I only use about 12 gigs max on the OS they are lasting a long time...... If it were not stable I would complain.

Being a mod, and developing some stuff, I really appreciate a little extra speed. I'm in/out/booting/shutting down/restarting way more than most people.

Using RAM is nice but not as reliable.

Embedded devices (say routers and smartphones) generally survive significant abuse, mostly because they live in a ramdisk that only seldom writes to their OS "drive" (nand flash or whatever).
Also FreeNAS does that with the "embedded install", or at least did in the past, now there is no more choice but they strongly advise to use USB falshdrives so yeah, probably embedded again.
Nas4free leaves that choice of installation afaik.

I'm assuming that doing a proper embedded system isn't a top priority for now.
OMV needs to grow in areas where it matters more (like say features), and resources are limited.

After all, SSDs are cheap nowadays, so apart from people like me, everyone is fine anyway.

Yep, same here. That's a different use case though.

the MoBo was not compatible with any usb header plugged on that 9 no sense pin.

I'm suspecting the mobo or the case was HP/Dell/Lenovo/IBM/Acer/-InsertOEMnameHere-. Am I right?
They love to make proprietary non-standard connectors for everything.
Had to do some clever tricks to transplant motherboards from/to an OEM PC and get everything working.

If you buy boards and cases and stuff they usually match up because they do follow standards. That's the entire point of selling pieces and not a fully assembled machine.
If you buy an OEM-assembled PC then they want you to not be able to fix it by yourself (and pay them to get "compatible parts").

So..... let's do this stuff easy, at the beginning.

No problem with that. Just saying what the "optimal" is imho.
