UPS choice

[janne.hallenius]

Hi!

Having had a look at this page,

http://www.networkupstools.org/stable-hcl.html

and with my power consumption taken into consideration, for the system that needs UPS power, the following two UPS:s are my candidates:

http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SMT1500I&total_watts=50

Will they work if I want an automatic shutdown from FreeNAS, I figure they will according to the list above!?

Talking to the distributer they do recommend the second one, mostly due to it's much lower "switchover time", practically zero. The person I talked to asked me if my system can tolerate a switchover time of 10 ms and to that I said I don't know! I have no clue or am able to find that.

Finding any reliable advice in general regarding UPS:s and specifically for a FreeNAS 8.3 solution is not easy.

Does anyone out there have practical experience from any of these two or maybe something else in the same class. How do the behave in case of a black- or for that sake a brownout?

I live in Sweden and the electrical grid is of no concern really when it comes to voltage stability and my house has a proper total protection system for voltage peaks due lightning etc. voltage 230V

Best regards

Jan

The first APC device you linked I have sitting 2 feet away from me. Never given me a problem with my Windows 7 machine. I even had a surprise thunderstorm and lightning hit the transformer on the power pole on my property. I lost my router and cablemodem and 2 clocks. My computer was on and continued to run until I shut it down since the transformer went up in smoke.

No clue if it works in FreeNAS though.

I've two units similar to the second APC devices you linked and after 4 years of service the older one needs a battery exchange, the other one is only 2 years old. Both have hold on to every time the power has fallen out. I'm using them with a Windows 7 machine and an iMac without any problem. I haven't tried to configure them with Freenas, but the apear in the N.U.T. Hardware compatibility list, so the both should work fine.
