I have a client who is looking at an unlimited advanced server setup. He currently has a 2 node  cluster of SharePoint and wants to add Skelta to this.

I have been told that Advanced server is the way to go as it has fail safe/load sharing etc, but my understanding is that he would have to order 2 installs of unlimited Advanced server (1 for each node) to obtain the mirroring benefits.

Is this correct?

Thanks,
