[ANSWERED] Advice on a UPS for DS216J

Unread post by satkin2 » Sat Jan 21, 2017 7:00 pm

Hi,
I've got a Synology DS216J. I recently suffered a power outage, which appeared to damage on of the drives in the NAS. As such, I'm wanting to invest in a UPS so that should I get another power outage the Synology will gracefully shut down and avoid drive damage.

I've been looking on these boards and elsewhere online, but don't really understand what I'm all the stuff I'm reading means.

Could anyone please advise me on the best solution to be able to look after the Synology better than I currently do. I've no requirement for it to run long after an outage or anything like that, just to shut down rather than just have the power pulled on it.

Many thanks.

It is of course very dependant on your personal situation. How common is it for the power going out in your area. And it is because the power company is acting up or because of local problems?

Does it matter? I think it does. Examples...

Where I live (The Netherlands) we have an extremely reliable power grid. In fact, if the power goes out anywhere in the country, it is national news for as long as the power is out. We will hear it on the news every hour while the outage lasts "citizens of Amsterdam are still without power". It is even so very uncommon that I remember exactly that the last time I experienced a power outage, it was in 2011 and before that is was 1999. Both times lasted a few hours.

I have a friend who lives in a very crappy house. He is blowing fuses on a weekly basis. He can't seem to pinpoint what the problem is, sometimes a few weeks go by without problems, sometimes his power goes down 5 times a day.

What's the difference?

In case of a wide-spread power-outage that will last hours, there isn't really much use in getting a huge (expensive) UPS that can keep the NAS running for a long time. Most likely your internet connection died along with the outage, your computers will be down too, unless they are also connected to the UPS. If the UPS can even keep the NAS powered for a minute or two it will be enough for it to gracefully shut down.

For my friend, however, I advised him to get a UPS that can keep the NAS running for at least half an hour or so, without the need to shut-down. When HIS power goes down, it is mostly just a section of his house. Most of his computers will still be powered up, his internet connection is also fine. So if he can manage to restore power within a decent time, everything will just keep spinning along nicely, without the need to power up the NAS again. As long as the TV is still powered on, his kids can even keep watching the movie that is streaming from the NAS.

Thank you. I've seen that page, there a re 28 suitable for my Synology, but I don't understand the requirements to know what's ok, or what's overkill.
I'm really just looking for the most simple solution I can get. But as UPS's are new to me I don't really understand the specs I'm looking at!

Thank you. That makes sense. Although more frequent than the power outages you get in The Netherlands, I'd say they're pretty infrequent, maybe once or twice a year. Whenever I've had one it's not lasted that long either, maybe an hour or so.

You're correct, my internet would go down too. Going on what you said above, it looks like I'd only need a fairly low powered solution then. All I'm after is for the NAS to shut down correctly.

I've looked on the NASs specs and see the following in the power details.
Power Supply Unit / Adapter 60W
AC Input Power Voltage 100V to 240V AC
Power Frequency 50/60 Hz, Single Phase
Any guidance on the type of UPS would be greatly appreciated.

Many thanks

I am anything but a UPS specialist. I like the APC models, simply because I have seen/used a few and they seem pretty reliable. I'm not sure if all the models support it, but the ones I use(d) have/had batteries that could easily be replaced. So you don't need to buy an entire new UPS if the battery is wearing out after years of use. But that doesn't mean that any other brand would be any less, I simply don't have any experience with those.

The only brand I won't ever trust again is Trust (how ironic) since we once had one at the office that simply blew up, knocking out the power in the entire building. Kind of the opposite of what it was supposed to do. :shock:

Just make sure that the UPS you choose has the ability to signal the power-loss to the Synology so it can actually start the shutdown of your NAS. Some of the very cheap UPS boxes simply have a power input, some power outputs and a battery in between. These would work okay if you are actually present when the power goes out because they mostly start to beep and you can then take action. But they have no way to "tell" your NAS that the power is out and that it should shut down. The NAS will simply receive power from the battery until it runs out and then still shut down suddenly.

I'm not sure if the devices listed in the link BritInCali gave all support this signalling, but I kind of assume they do. Because that is basically the only thing that needs to be "compatible" I guess. For the rest a UPS is just a relatively simple box, power-in -> battery -> power-out. The actual price will mostly depend on the power it can provide, the actual quality of the batteries used, the ability to signal devices over USB, serial connection of even ethernet and some extras like displays telling you about the amount of power left.

Sorry for not being able to give specific advise on models. I'd just go for the cheapest model of a reliable brand that is supported by Synology. All of my boxes are able to shutdown within a minute and I can't really imagine that there would be a UPS available that can't even keep one device running for 60 seconds.

I'm using this one and I'm really pleased with it's performance. mod note: shop link removed

Hi,

For what it's worth, I have a DS216+ II and I was in the same situation as you. The Synology compatibility list is a bit outdated, but if you can find a specific model on that list that is compatible with your DS it's better to go with it.

As for me, I ended up with a model that is not on the list. But after testing, it seems to be working fine as it's communicating with my DS and I can configure my DS to shutdown after a certain time in case power is not restored.

The UPS uses a USB cable to connect to the DS (so you're losing one port for that, but it's worth it).
On DSM you can go to control panel>hardware and power>UPS
And set when your DS should shutdown when it's on battery power (provided by the UPS when the power is lost).
Once the power is restored the DiskStation will startup again (setting under the General tab).

usually UPS manufacturers provide examples on their website of how long (time) a particular module can handle a specific load (watts) before it's exhausted.

Some high end models use SNMP over the network for communication, but they tend to be big and expensive (more suited to data centers).

The UPS I have is APC BE700G. I hope this helps.

Thank you all for the guidance.

I ended up getting this mod note: shop link removed

Just one further question if I may. In testing it, I've pulled the plug out of the mains feeding the UPS. As such, it switches to battery power.

The Synology alerts me via email that it's switched to battery power, then after the minute I've set it to take to enter safe mode, it sends another email stating this...
The UPS connected to <NAS Name> has reached low battery. All services are shut down. The services will be restarted once the UPS is recovered.
The terminology seems a bit strange. The UPS power remains at 100%, but I assume this is the safe mode kicking in, it matches the timing I've set. Does the phrase
All services are shut down.
mean that should for whatever reason I be unable to shut the Synology down before the UPS runs out, that it will handle this securely, rather than just losing power, like with a power cut? The status light goes out at this point, but the drives and power remain lit, so I'm a little confused.

Many thanks.

I'm getting the same message stating that the battery is low. As you said, I believe it's just a generic message and doesn't reflect the battery level.

I believe once you have "the all services are shutdown" message this means it's safe to turn it off. What's important is that the system has gracefully unmounted the drives (in addition to shutting the rest of the services).

I've set mine to turn off the UPS after it shuts down (thus preserving what's left of the battery, in case the power returns and dies again). So it's effectively turning itself off. Unless you have something else connected to the UPS that you need to keep running on UPS battery, I believe this is a good option.

Once the mains power returns the DS will startup. Just make sure to check "restart automatically after a power failure" under the General tab.

I hope this makes sense :)

I believe so too. Apparently the Synology will by deafult automatically enter "safe mode" (unmounting all volumes and stopping all services) when the battery reaches a low level. You are then send this notification by e-mail. Looks like it's just a little bug/mistake that it will also send out this default message if it entered "safe mode" because you told it to.

You don't need to actually shut down anything before the battery of the UPS is fully drained. The whole idea about "safe mode" is that is doesn't matter if the power is suddenly cut from the Synology. Because there are no services left running and no volumes mounted, no harm can be done by just "pulling the plug", either literally or by running out of juice in your UPS.

Ah, turns out I was too eager to ask questions.

I just tried it again and as I said, after a minute the Synology sends the message. What I missed before was that it then appears to go in to the shut down process. A minute or two later it was off and the UPS was turned off too.

I turned plugged the UPS back in and hey presto, just like you said, the Synology reboots too.

Working perfectly, and just what I'd hoped for.

Thanks again for the advice and guidance.

Have a new Synology DS416play recently had a power outage and the unit did not auto restart when the power was restored. I only noticed when got backup errors and manually restarted.

Know I can hook it up to a UPS .....

Questions:
Is there anyway to hookup the UPS through say the USB connections on the Synology DS416play so it will sense the UPS signals when power loss and the Synology DS416play will auto shutdown and auto restart when the ups senses power restored?

Thanks,
Archer

Yes. Mine connects using a USB to RJ45 cable. The RJ45 end is like that on the end of a phone handset and plugs in to the UPS. The USB then just plugs in to the back of the Synology.

Once you've connected the UPS to the Synology, you can go to the Hardware and Power section of the Control Panel. In there you'll find a UPS section. You can then choose to enable UPS support, turn off after a given amount of time on UPS power. In the General tab, if you choose Restart automatically after a power failure, once your mains electricity returns the Synology boots up, unaffected by the power cut and continues as normal.

I couldn't recommend getting a UPS more highly. My Synology sends me an email when it connects moves to UPS power. It also emails me when it connects to a UPS after a restart. A few weeks after I got mine, we had severe winds which caused a large number of momentary power cuts at my house, just lights flickering etc, but without the UPS it would have been like pulling the plug on the Synology then restarting it multiple times, an easy way to fry the hard drives. Instead, I got a lot of emails updating me of when it was on UPS power and when it was back on mains, but it remained un-impacted. It would be a very worthwhile investment.

Hi, I have a ds216+II as well and I'm unable to find a compatible model on the list in the website. May I know how did you shortlist the model you mentioned below?

Hi,

I was in a hurry as I had a long trip coming and I didn't want to leave my DS without a UPS. I went out to the market looking for one to pickup, I had a certain budge (~$100) and standby time (~15min) in mind and a wish that the UPS will communicate with the DS, I've also wanted a small unit that can blend in with the setup I have at home. Looking at what's available on the shelf and doing a quick look on Amazon reviews (very good for this model) I ended up buying it knowing that I can return it if it doesn't work, but it worked well-- until last week :-(

I waneted to work on some electrical outlets at home and I went to the tripper panel to turn off some zones. Accidentally, I turned off the one the Synology DS is on and the UPS buzzer immediately went off (mains power lost alarm, this is normal), notification pushed to my phone instantly that the DS is on UPS power, but suddenly seconds later the DS crashed (the UPS power to the DS was lost).

The UPS malfunctioned and after examining it I ended up contacting APC and they agreed to send me a new one under warranty.

However, I've lost power before and this UPS handled the situation very well, communicating with the DS to gracefully shut it down, so hopefully this was a one-off problem and that the replacement will work well for a long time.

The DS reports around 25 min of UPS standby time. I've never tested that though, I've configured it to shutdown the DS after 5 min if power doesn't return and in the few occasions when the power was lost that's exactly what it did.

I hope this helps :-)
