[AusNOG] Who makes good UPS gear besides APC?

[Chris Gibbs]

Is anyone considering fuel cells a suitable replacement for UPS?

I would think that refuelling them would be relatively easy.

I would also imagine, if they are being considered that data centre
operators would not let them in the building, let along power stuff.

In that case, they maybe more suited to private run smaller server rooms ?


On the same point regarding alternative power sources; considering DC power
is more efficient (i.e. no loss wasted on conversion), why aren't more
people going down the route of DC powered servers and storage ? A couple of
rectifiers and some deep cycle batteries would be overkill for most small
requirements. I think the open compute project is trying to go down that
road.
