Scalable and Cost-Effective Interconnection of Data-Center Servers Using Dual Server Ports

The goal of data-center networking is to interconnect a large number of server machines with low equipment cost while providing high network capacity and high bisection width. It is well understood that the current practice where servers are connected by a tree hierarchy of network switches cannot meet these requirements. In this paper, the authors explore a new server-interconnection structure. They observe that the commodity server machines used in today's data centers usually come with two built-in Ethernet ports, one for network connection and the other left for backup purposes. They believe that if both ports are actively used in network connections, they can build a scalable, cost-effective interconnection structure without either the expensive higher-level large switches or any additional hardware on servers.
