You should invest in a Spider KVM or similar, they hang off the back and don't use any rack space. They can also be POE, so they wont use a plug. That'll provide you out of band management and remote reboots and what not.

I have a CentOS-5.6 remote server in a house in Italy,
where there are occasional thunder-storms.

There was one yesterday, when the electricity
went off 3 times, for a second or so on each occasion.

My server, an HP MicroServer,
came back (re-booted) on 2 of the 3 occasions,
but not on the third.

I assume that the problem arises because the machine
does not close down properly.
(Although it is also possible that a voltage surge
might have been responsible -
I have no surge protector on this supply.)

It seems to me that it should be possible
to have a simple, torch-battery operated, system
which will keep the machine alive long enough
to make a graceful exit.
A full-blown UPS would be excessive, I think,
as I only want the machine to re-boot
when the current comes back on.

I know there is a Remote Management (iLO) card
for this machine, which might be useful for this.
Unfortunately, I've already used the PCIe slot
for a second ethernet card.

Any advice or suggestions gratefully received.
