tibberous Posted November 24, 2008 Share Posted November 24, 2008 My server runs raid, so if a hard drive fails I have a backup. I have a backup power supply too. I'm worried the motherboard could fail though - if it does, I'd be server-less until I could order a replacement and fix the server. I don't *think* this is an issue for he processors - can I run a dual process motherboard with only one processor? I don't know - and that's why I'm nervous. I'm thinking of buying a new server, so that, in the event of horrible failure, I can switch the hard drives, be back online, and then fix the other server without having to rush. Is this smart or overkill? I know motherboards don't fail all that often, and would think server motherboards would fail less -- I'm not sure the best, practical way to avoid downtime.

jcombs_31 Posted November 24, 2008 Share Posted November 24, 2008 If it is critical to always have up time, then yes a backup server would be nice. You can even run a mini cluster to make sure you are always utilizing both servers. Quote Link to comment Share on other sites More sharing options...
tibberous Posted November 24, 2008 Author Share Posted November 24, 2008 If I run a mini-cluster, and one server fails, is there another copy of the data on the other machine, so the system stays running? It would be nice to just be able to buy two cheap servers and be sure they'll stay running. Quote Link to comment Share on other sites More sharing options...
revraz Posted November 24, 2008 Share Posted November 24, 2008 Yes, if you use them as a load balanced farm and not fail over. Quote Link to comment Share on other sites More sharing options...
tibberous Posted November 24, 2008 Author Share Posted November 24, 2008 I'm reading about it on Wiki, but the information is all conceptual. Is it hard / expensive to setup? Does anyone know of a good guide / ebook / article I could use to get started? Quote Link to comment Share on other sites More sharing options...

ILMV Posted November 26, 2008 Share Posted November 26, 2008 Be careful, if your mobo fails and your stupid enough to run windows as a server, you may find that you will have to drop the exact same motherboard in there for the windows installation to work as it did. This does not always apply, but when it does, the only work around is to 'repair' windows this could be extremely problematic. Do you keep your OS and data on the same disk?
