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=BR1500GI&total_watts=200
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
