Yes but in most cases unless you have segregated power both UPS's are on the same commercial feed. If power goes out for one UPS it will go out for the other and would it not be better to have the server shut down, rather than "hope" that the second UPS did not give a false reading and just die before the server was down? Again that is assuming you do not have multiple Commercial feeds to power the UPS's.
-----Original Message----- From: John Hornbuckle [mailto:[email protected]] Sent: Friday, July 15, 2011 9:27 AM To: NT System Admin Issues Subject: RE: Server 2008 R2 on Multiple UPSes The scenario I'm thinking of is this... Let's say the UPS that's connected to the server via USB experiences a problem that causes its battery to quickly drain. If that happens, the server is going to shut itself down since that's what I've configured the power settings to do. But the second UPS-the one that's not connected to the server via USB-may be working just fine. Since the server is capable of running with just one power supply, there's not actually a need for it to shut down. The server wouldn't know this, though, because it's only monitoring one UPS-the one that has the drained battery. From: N Parr [mailto:[email protected]] Sent: Friday, July 15, 2011 10:06 AM To: NT System Admin Issues Subject: RE: Server 2008 R2 on Multiple UPSes Run time should be close to same on both so if it were to tell the computer to shut down both UPS's should be at run time limit. Assuming they are smart UPS's put a NIC in the one that isn't plugged into Server to monitor over network. ________________________________ From: John Hornbuckle [mailto:[email protected]] Sent: Friday, July 15, 2011 7:56 AM To: NT System Admin Issues Subject: RE: Server 2008 R2 on Multiple UPSes That's how I've done it up until now. But with this new server, the setup will be a bit different. I have two UPSes dedicated just to it and its attached storage system.
