What kind of services needs failover? Just plain files? Have you looked at CODA? http://www.coda.cs.cmu.edu/ It might be possible to set up to coda replicated servers. But I'm not sure how this replication works. :) But it might be worth a look. I also think it's possible to store data on a SAN, connect both servers to it and when the master fail, make the slave mount whatever it needs. But this kind of solution costs money, and you have to place the SAN on one of the locations (or a third), so if you have a fire or anything you will lose it. But it would be much easier to help if we knew what kind of services you need failover for...

Data loss or downtime on it is not an option so we have a hardware RAID 1 and also a second "hot host" (in another building) which replicates data from the main one every 30 minutes (via rsync). However it is this 30 minute window that concerns me because that leaves us open to 30 minutes of data loss. So basically what I'm asking is (without switching to Sun equipent) is it possible to do some sort of network RAID where data is written to both systems simultaneously? We need our system to carry on with no data loss even if one of the servers should suffer a complete system failure (ie be blown up or thrown out of the window)...... --------------------------------------------------------------------- Faxes delivered directly to any email address, new to mBox!
