SG-1100 ZFS
-
I am looking to deploy a number of remote routers, connecting via OpenVPN.
These routers may suffer occassional power loss and I am aware of the potential power down / reboot issues with UFS.Is it likely to be an option to use ZFS on an SG-1100 in the near future; or should I look at using APU2 for reliability?
(Throughput speed is not a priority, as they are on a mobile data network) -
With 1GB ram and eMMC for the SG-1100, I wouldn't recommend ZFS.

So for reliability at remote sites I can assume that an APU2 with mSata SSD on ZFS is a better bet, given that power outages may occur.

Why not opt for a UPS and with the help of the NUT package shut down your pfSense safely?
Even the Nano images (aka read-only) weren't proof to survive improper shutdowns. I've had ALIXes with Nano on CF-cards dislike it seriously.Or: with the ability of the SG-1100 to be also powered from the mini-USB port all you need is a power bank. These devices only consume one Watt or so.
With a 12V relay (fed from the main PSU) trigger one of the GPIOs and run a script to shut itself down. Easier and less error prone than trying to find a solution that hopefully reboots after a blackout. -

I realize this is way off-topic, but how does one actually do that?
I've got an SG-2440 hooked up to a CyberPower UPS. The NUT package is installed and talking successfully with the UPS, but I don't see too many options to do any shutting down. Got any tips, or point me to somewhere that has them for shutting down safely? Thanks for any help!

Okay, food for thought there.

A small internal battery with power loss detection and soft power down would be a nice feature.
-
Built in battery would be nice, but now we would have to worry about placing that, having air flow and working on the mechanics of getting it to interface with the hardware. All of that work would be expensive to undertake, don't forget UPS batteries need to be changed out.
A UPS is ~100$, and tools like NUT or APCUPSD already part of the packages, this will protect against outages and brownouts.
You could spring for a larger battery and have it run your switches and ISP provided equipment to help with short power outages/brown outs keeping the office productive during the time for things that would normally need to power on.
-
All valid points Chris.
I just wonder how many users out there actually log on to the web interface of the road warrior boxes and soft power down (using halt) before removing power.

No offense intended, but dude, that's a 20+ page, 450 post topic you linked me to... I'll start looking thru it. Thanks!

Is this correct?
Do you mean you can power it through the Micro USB Console port ? -
No, it cannot be powered from the USB port, any of them.

Thanks Stephen, I didn't think this was correct

uhh, that's strange.
OK, just looked at the Espresso.bin block diagrams and found a v3 where it was possible (which I must have remembered) and the v7 which is the SG-1100 in most parts where it's not anymore.
Sorry for the confusion ... but would have been great.
-
I agree it would in some ways. It is deliberately disconnected in the SG-1100 though.
If you look at that diagram the12V is only really used for the SATA power supply and that is not populated on the SG-1100. It's why I suggested above that if I was looking at battery power I might look at driving it from 5V directly. Or potentially a battery at something less than 12V (or at least less than 13V).
But don't do any of that!
