I'm currently in the process of designing a solution to shutdown a two Ubuntu Server cluster that uses heartbeat and DRBD to replicate storage and offer a NFS share to some IP cameras.
We want to integrate a UPS into the system so the servers will shutdown gracefully. I'm currently looking into the APC Smart-UPS C 1000VA 2U LCD 120V UPS and using Apcupsd to shutdown the servers in the event of a power outage.
Is this idea possible? I'm reading through the documentation right now. If you guys have any better ideas I'm open for suggestions.
