The physical architecture of a cluster implemented with SC3.0 software is similar to a cluster implemented with SC2.2 software, in that all nodes must have the same version of the Solaris OE and all nodes must be connected to a private network of redundant high-speed interconnects. However, unlike SC2.2, not every cluster node needs to have physical access to shared storage.
Pair + N (new to SC3.0)
SC3.0 software has the option to make network interfaces highly available. If a node is to be available via a public network, it will require a network interface. If redundancy is required, interfaces can be configured in a redundant group. Also, if a node hosts ...
