SERVER FAILOVER // AUTOMATED PHYSICAL NETWORK CONNECTIVITY
Posted on 2000-03-16
I have a somewhat complex problem that I am asking for a possible solution. I'm going to set this point value high because of this.
I have a server, which is essentially a passthrough server for a database, e.g. it holds no data that we care about, so we image this server with Norton Ghost. If the server fails we restore the image.
The problem is this, we need very little downtime, and the time to re-image the server isn't much its still too long. So, our solution is to have a server on standby but unplugged from the network (otherwise you would get IP conflicts). Anyway, this is a partial solution, since it still needs human intervention.
What we are looking for now is to have both servers ON but only one server plugged into the network and have monitoring detect a failure, then somehow switch over to the standby server. Anyone know of a physical switch that will allow this via some sort of remote commands? Or any other solution? We have LEGATO/VINCA, however this is *NOT* a viable solution, it corrupts our data in our current environment.
I am mostly looking for some device (or other solution) that will allow one server to be plugged into the net, and the ohter server be unplugged at the same time then reverse this via some sort of automation. Power cycling is not an option either, since it defaults to OFF when the power is off, and never comes on by itself when power is restored.
Sorry its so long.
I will offer 800 points for this question.
