I have 2 systems that will be not be accessible to users, and will frequently lose power, one is running windows7, and one is redhat linux. Is there some settings I can do so that they don't require a soft shutdown? Linux machine is running ext4, and windows ntfs. Thanks.

some ups software might do this....that's the only way i've ever dealt with this –  hbdgaf Dec 16 '10 at 14:55

I would put them on a small UPS and have the UPS invoke a shutdown when power is lost.

I can't have a UPS, I need the OS to be able to take it. –  CptanPanic Dec 16 '10 at 14:58

If you can't use a UPS you options are quite limited. In windows 7 you can probably tell the OS to reboot in the event of a power outage (I am sure you can do this in Red Linux as well). I wouldn't recommend this as frequent Hard Shutdowns will eventually lead to some sort of file/disk corruption that could be irrepairable....

Depends on what you're using them for. If you can make your complete Red Hat solution fit on a DVD, you can boot off that and not even use a hard disk, which makes power outages less of a problem. This would work if it's a router or firewall, not so much if it's a file server.

I can't boot off a DVD either. Do I have to make fs readonly? –  CptanPanic Dec 16 '10 at 15:03
    
You don't have to make the root filesystem read only, but it would certainly increase fault-tolerance. I gather you don't want to spend much on this? The other suggestion about a UPS is good (and both boxes could share a UPS). –  CarlF Dec 16 '10 at 18:48
