BUILD Looking for a UPS

[MtK]

Hey,
I have this system:

• Intel Pentium G2020
• Supermicro X9SCL-F
• 2x8GB ECC RAM
• 6xWD Green in RaidZ2

Could someone please recommend a UPS for this system?

APC Back-UPS Pro with a VA rating to match your wallet.

don't I need some kind of a minimum here?

i.e the 550 VA states 330 Watt.
is that enough?

Deciding on the UPS nearly as complex as building your server and will depend on your needs.

When I bought mine, after doing some research, learning about sine wave, the need for the UPS to shut down your server, etc I went with a APC Smart.
It works, but the integration with FreeNas is not great. I can only get it to work with the USB.

ok, fair enough.
let's start with the basic and minimal feature: allow the server its seconds to properly power off when AC is gone.
(no real need for the server to keep running, if that means a lower/cheaper APC)

I've seen a number of good reports here on the CyberPower units. I have a CyberPower CP1500PFCLCD, and have found it to interface fine with my FreeNAS server and notify the server of outages. I haven't had an outage long enough yet for the server to need to shut down. The 1500 is probably overkill, but I do also have my main router/server and my primary Ethernet switch attached to it.

so basically, I'm looking for an APC that can provide the same Watt as my PSU (+ some extra), right?
so if I have a Seasonic 450W, a 500W PSU is enough to let the server gracefully shutdown?

 

[marbus90]

For your system ~100W from the UPS side should be enough. Even at 100% load most UPS's will hold for 2-6 minutes.

I'll look into passing trough the USB of my BackUPS Pro 900VA to the Debian VM, running a NetworkUPSTools server in there and shut down both the server and the workstation on the UPS gracefully - if there's less than ~5 minutes left in the batteries. That'll keep me working for another half hour easily.

 

[MtK]

the BackUPS Pro 900VA provides far more than 100W!

 

[marbus90]

There are smaller sizes. I've got the 900VA since I'm running my whole desk off it.

 

[SweetAndLow]

I like one that can handle my nas, router, switch and modern so when the power goes out I can still get an email from my server saying it's on battery.

 

[AxeL]

I have an APC Smart-UPS 750VA (~550W) which works great with FreeNAS

could you tell for which system?

Watch out for APC UPS devices with Microlink! Check this thread on the APC forum first.
FreeNAS uses NUT, right? See also 'supported hardware' in the apcsmart(8) driver for NUT.
I stopped buying APC units.

to the OP...

First you must realize how important the UPS is to your system. It is as vital as your data is so do not buy cheap unless you are only shooting for minimal protection.

When you purchase an UPS you need to have a few pieces of information handy...
1) How long do you want the UPS to run your system during a power outage?
2) Do you have frequent Brownouts or lots of small power drops in a very short period of time?
3) How much power does your NAS server pull when fully engaged?


If this is strictly a home system then my advice is to purchase an APC Back-UPS Pro BR1000G or similar sized UPS, set the UPS setting to shutdown when UPS reaches low battery. This will give you enough reserve power to give the NAS time to shutdown with time to spare.

If you need to cut costs do that with the case (but keep the hard drives cool too), everything else is actually important in making your NAS run error free.
