Develop a hot backup system (also know as hot swap system)
My boss asked me to do a feability study on whether we can develop a "hot backup" rather than a clustering system.
My plan is to use 2 identical PC with win2K adavnced server installed, each PC have 4 network cards installed. On each PC 2 network cards will be used to link directly to another PC through crossed wired cable, the rest 2 cards will connect to network switch.
What I don't know is; do I have to develop virtual network driver or virtual I/O driver to isolate 2 PC from external ( means other PCs on the network will only see one PC).
The benefit of this architecture is that once a PC down, the other will take up the task immideately with zero down time. (cluster system will have a fail over down time)
