Hi, I won't call it akademic curiosity. Let's say you have two rooms with a distance of 5km. In theory both network connections are completly independent, but in real live there are a lot of possible reasons, why they are not independent. It might be just a human errors or a technical problem like a running spanning tree.
In theses cases it is very helpful to have a technical independent solution like heartbeat over fibre channel disk to avoid a split brain. I'd like to have the idepentend way to prevent a split brain situation. The network technology is one technology (even with redundant connections), so a potential SPoF. A disk heartbeat would add a second technology. Cheers, Ulf -- NEU: FreePhone - kostenlos mobil telefonieren und surfen!
