ReadyNAS 314 - Recommended UPS?

Polite bump? Any advice for a UK user?

I'm thinking of a "APC BE700G-UK 405 Watts /700 VA,Input 230V /Output 230V, Interface Port USB Power-Saving Back-UPS " from Amazon http://www.amazon.co.uk/APC-BE700G-UK-Interface-Power-Saving-Back-UPS/dp/B002RXED6A/ref=sr_1_1?s=computers&ie=UTF8&qid=1406842132&sr=1-1&keywords=APC+BE700G-UK+405+Watts+%2F700+VA%2CInput+230V+%2FOutput+230V%2C+Interface+Port+USB+Power-Saving+Back-UPS

Do you think this would suffice?

Per the link some models might not have the USB connection. You need that for the NAS communication link (and you don't want the kind that requires a serial to USB converter).

I'm in the US, so I have no knowledge of UK models.

Have you had a look at the APC runtime calculator?

As StephenB mentioned you must make sure you get a UPS with a USB port. Most APC UPS units with a USB port should be compatible.

For the NAS to shutdown safely you should allow for at least a few minutes of runtime.

For battery longevity it is often recommended not to put more than 80% load on a UPS. If you put too much load on a UPS the battery will drain too quickly shortening its life and need to be replaced much sooner than otherwise.

Will you put other devices on the same UPS?

You can share the UPS via your network (in which case the router/switch also needs to be on the UPS - though these can be left to power off when the UPS battery has drained) with other ReadyNAS units and even PCs and Macs.

Hi, sorry for all the questions, I'm new to this! :)

From what I can see, the ReadyNAS 314 uses 69W at Full Power, my computer monitors use (95W, 145W, 145W) and my PC has a 750W PSU. I plan to get a wattage tester to see how much wattage is actually being used. Mainly I just want to protect the NAS, anything else is a bonus.

The BE700G-UK runtime is at: http://www.apc.com/products/runtime_for ... sfamily=29
And the Spec sheet says it has a USB port: http://www.apc.com/products/resource/in ... E700G%2DUK

So, apart from calculating my wattage of the PC/monitors, it looks like this UPS would suffice? Would you agree?

I wouldn't put the monitors on the UPS.

Although this was written for old model ReadyNAS units you may find this useful: http://home.bott.ca/webserver/?p=466

If you want to protect other stuff, I'd suggest getting a higher capacity UPS.

I wouldn't either, unless the UPS had a bigger battery. I'd connect the monitors to a surge protector instead (most UPS have surge protected outlets that are separate from the ones that maintain power).

I protect a desktop PC chassis (but not the monitors) as well as my NAS. However, the desktop PC is in sleep mode when I'm not actively using it, so it has no real impact on the UPS run time. The idea is that the PC won't shut down over short outages.

The PC is not monitoring the UPS, so if the UPS battery runs down it will not shut down cleanly. I don't have many long outages, so that is not a big concern.

I have 2 of those, they do have USB connectivity and are compatible with readynas.
I have one that protects an ultra 6+ with 6 disks and the readynas reports about 40 minutes of battery backup time.
I have another supplying a 316 with 5 drives, a 16 port gigabit switch, and a PC with a 400W power supply, readynas reports 16 minutes backup time.
Not sure how accurate these times are; and of course you'd normally set to shutdown well before max battery backup time.
It works for me but I just need enough time for everything to shut down cleanly, nothing more.

Am using the first generation model of the BEG700 (Without the Eco Button) and it works well. If you have your PC connected to the UPS for power too, you can use WinNUT to have a service running on your PC that will also shut it down when the UPS goes on battery power. You will have to allow "Remote Monitoring of Connected UPS" and specify the IP address(es) of those devices on the network you wish to allow access to. For this I use 192.168.0.0/24 (all devices in the 192.168.x.x address space will be able to monitor the UPS via the NAS indirectly).

Just be aware that with your NAS and desktop PC attached to the Battery side of the UPS, depending on the power requirements of the PC, you may be draining the UPS too quickly if/when it goes on battery power.

I set WinNUT to shutdown the PC as soon as a power loss occurs, but set the timeout on the NAS to "Automatic". This is with a PC with a potential draw of 800w. Emphasis on the "potential" part.
