Objective of centralized repository is to arrange an outsized number of server machines with little apparatus cost while providing high planning facility and bisection width. It is well understand that the present practice where servers are linked by a tree hierarchy of network switches cannot gather these necessities. In this paper, the authors find out a newest server-interconnection structure. The Structure observe that the commodity server machines used in today's centralized repository generally come with three ports, one for network connection and the remaining for backup purposes. The model supposes that if three ports are aggressively used in network connections, they can construct a scalable, cost-effective interconnection structure without either the luxurious higher-level large switches or any additional hardware on servers.
