QNAPTS-431XeU-2G-US 4-Bay 1U Short-Depth Rackmount NAS with Built-in 10GbE Network 4 GB RAM TS-431XeU-8G-US

We use this unit to restore our VM backs in case of data corruption etc with a 10Gb connection very fast

did what i needed

This is a NAS storage device with 2 gigabit ethernet ports and one SFP+ 10G port. It does not come populated with any hard drives. The NAS is intended to mount in a 1U slot. Note that the 1U slot must have a mounting position in the middle of the slot, as the screw hole on the mount kit is in the middle of the plate and not on the top and bottom as many other rack-mounted equipment.The device autoconfigures using DHCP for the initial setup. However, I did have one slight problem trying to provision this device: it detected the other QNAS device I had on my network and seemed to pick up the configuration (IP addresses, storage setup, etc). I ended up doing a full reset of this device in a segregated network, reconfigured it there, and then installed it onto my regular network.On a side note, at the time of this writing, Amazon is limiting many hard drive purchases to 2 per month. Make sure you plan accordingly if you do not have the hard drives available.Update:. If had to remove a star due to a design flaw. After procuring some hard drives from a competitor, I loaded this bad boy up. However, with the addition weight of the drives, the unit started leaning significantly in my rack. Thinking it was loose screws, I double checked and everything seemed tight. However, I think the problems are compounded. Not only does it mount into the rack with one screw per side instead of two, but the mount brackets only have screw slots in the middle and bottom. If there was a mounting hole on the top of the bracket and if they used 2 screws per side instead of one, I think that would have helped immensely for stability (without having an object in the lower slot to keep it propped up, I guess). Looking at the price QNAP is selling their rail kits, I guess I see why they did it this way.

I normally use Synology NAS boxes but wanted to try something different. The unit has very high quality construction and it worked perfectly from a mechanical perspective. I am just not fond of the OS. For most users it should be fine, but I was planning to incorporate it into a hybrid cloud configuration with my website being partially hosted in AWS S3 and using a home-grown script to maintain the link between my Qnap server's dynamic IP and Amazon Route53. I have all of this set up and working under my Synology servers, but moving it over to the Qnap box was proving very difficult. Eventually I just got tired of trying; the effort was more than the benefit.For those who don't have this kind of advanced infrastructure it would be great.

QNAP has a very good feature set for the price. Their management interface is very good. I did have some issues getting their certificate to work through my firewall. I wanted to try something in the newer firmware, unfortunately I haven't been able to try it yet (read below). If I allow the array to auto configure (UPNP) the array took over for my website. It wasn't a problem for me, I just disabled UPNP on my firewall, and I was back on the air. The newer firmware looks like you can configure which services to setup, so that may no longer be an issue.The SFP+ port works great, I doubt it will scream without SSD's but that's ok. I was impressed by the transfer rates compared to the array this is replacing. And since this unit is shorter depth, it works great in the network cabinet in my home office. Everything seemed perfect, but...The array died after 3 weeks. I reached out to QNAP and they replaced it, but the replacement died in 2 weeks. Both units died in similar ways and would not power on. Unfortunately for me, this has now stretched past Amazon's return policy. I reached out to Amazon, and they are unlikely to allow me to return this now. So I am stuck with a second dead array, and have to wait on what QNAP will do next. I am concerned this product may be a little too new to market, and has issues. I have nothing bad to say about QNAP, or their support team. It's just this model may have something terrible wrong.When this get's resolved, I'll try to find this and update what happens here. I really wanted to mark this with 5 stars but for now, unfortunately I have to rate this unit very poorly.
