Hi All:


I am interested at looking at NUT to manage shutdown response to power
outages more efficiently.


Presently I have an APC SmartUPS 1500 which connects to a "server" using
a USB connection, from where I run a shutdown batch file for our server


Currently I have 3 boxes running XCP with a number of servers on them, a
XenServer box with a number of MS servers on it, along with an internet
gateway server and a PBX.


The load on my UPS is around 40% and I have around 10 minutes of
run-time in which to shut down all of my boxes.  At the moment, because
some of the server apps are quite heavy, the shutdown time is not
sufficient because of shutdown time delays, and the batch file being
sequential, meaning that it executes a command, waits for a response and
moves on to the next command.


I would like to be able to issue a shotgun command to my VM boxes, etc.,
simultaneously, as the UPS run-time will then probably be sufficient.


I would appreciate comment on whether or not I can achieve this, along
with any additional guidance that you may feel would be good to have.
