Does anyone have any experience with hardening Suns against power events other than ponying up the cash for a full-blown UPS? It's my understanding that HP mini's all have integral power-fail detection and enough battery backup to shut down gracefully. It would be really nice to be able to put a board full of batteries (or whatever) inside each of my servers and not worry about my disks being corrupted by power outages. The reason for my sudden concern is that we had a "power event" over the weekend that damaged one of my disk partitions so badly that fsck wouldn't touch it. Since Suns don't seem to have any facility for orderly shutdown on powerfail, I've been thinking of putting together a setup that would include the following: - A power-conditioning system capable of attenuating spikes to the point that they don't pose a problem. - A small UPS capable of sustaining the machines for a minute or so. - A device capable of detecting a powerfail and causing the servers to shut down. The first two items are fairly straight-forward. I can think of ways to kluge up the third item, but am wondering if anyone knows of a product to do this.
