1. A method comprising: providing first and second nodes that are physically partitioned from one another, the first and second nodes being in a pre-merger state; configuring the first node to operate in a first predetermined address range while the first node exhibits the pre-merger state; configuring the second node to operate in a second predetermined address range that is non-overlapping with respect to the first predetermined address range while the second node exhibits the pre-merger state; and activating, in response to a merge command, a communication bus between the first and second nodes to merge the first and second nodes to form a merged physical partition in a post-merger state, wherein the first node may communicate over the communication bus with the second node via the second predetermined address range of the second node, and further wherein the second node may communicate over the communication bus with the first node via the first predetermined address range of the first node.
