Uninterrupted Power Supply Advise

[locrieth]

Hi all,

Just looking for a bit of advice regarding purchasing a UPS for my home server and network. At present I have a Dell R420 with dual 550 Watt PSUs which run a windows server 2016 VM and a Sophos UTM VM, a Cisco SG300 24 POE switch (which runs 3 POE APs and a CCTV IP camera), a Virgin Media SuperHub 3 and a media centre PC (i5 3330 with a bunch of drives).

I've ran a power meter on the mains plug that they come from and it reads about 250 Watts while idling and when i ran prime 95 on both the windows server vm and the media centre they went up to about 325 Watts, so call it about 1.5 Amps.

I've had a couple of trips on the power recently and I'm looking to try and mitigate short power drops, when all I need to do is flick the breakers back on. But if there is a longer power cut, gracefully shutting down the VMs, ESXi and the media centre PC in the battery time.

Any advice on what i should be looking for? I've done a bit of research regarding standby, line interactive, etc and simulated sine wave vs. pure sine wave. What VA /wattage should i be looking at? And are there any brands to avoid or specifically go for, cyberpower seem to be coming across as a good reasonably priced brand?

I don't really want to spend a fortune on one, but don't see the point in scrimping of one if its going to be rubbish.

As always your advice is much appreciated, thanks for reading.

Cheers,

Locrieth

Hey thanks for the responses.

So we've been having a clear out at work and I found a 3000 VA APC UPS, so I got quite excited, as it was going to be written off and I though I had found some replacement battery for £40. Unfortunately I realised that it took 4 of those batteries so the price suddenly jumped up to at least £160 and when I tried to plug it in to see it was dead as a door nail! Then I found a Riello 1100 VTS (1100 VA 880 W) which had an error on power on A53 (I think it was) which turns out was a battery issue, so I ordered some replacement batteries, which cost £60 and everything seems to be up and working, I've put my media centre PC on and its showing 7% load. Just need to get some more Male to Female Kettle leads to plug everything else in and install the software and give it a test. I'm a happy chappy now

Cheers for all your advice.

Hey all,

Quick question now I've connected everything up, has anyone had any experience using Powershield3 or Riello UPSs? My UPS doesn't have a network control card, so I'm going to be using the USB connection. I have My Windows 10 Media PC and a Dell R420 with ESXi 6.7 (running 2 VMs, a windows 2016 server and a Sophos UTM). What I want to achieve is a safe shutdown of the VMs, the ESXi host and the Windows PC. I had a quick look at a document and the first thing it mentioned was the virtual appliance version of powershield won't work on the free version of ESXi, so I'm thinking I'm going to need to connect the USB to the Windows 10 PC and then run some script to shut down the VMs, then the host and then the Windows 10 PC? Does this sound about right? I haven't installed the software yet, so just pondering how it was going to work before I give it a try tonight.

Cheers,

Locrieth
