Large numbers of commodity servers in a data center may be inexpensively interconnected using low-cost commodity network switches, a first network port on each commodity server, a second network port on each commodity server, and a traffic-aware routing module executed on each commodity server. Connecting two or more commodity servers via the first network ports on each server to a commodity network switch forms a unit. Connecting two commodity servers in different units forms a group. Each unit has a direct connection via a second network port on a commodity server in the unit to another unit. Each group may have a direct connection via a second network port on a commodity server in the group to another group. Traffic-aware routing modules executed on each commodity server determine routing of data between servers and balance traffic across the first and second ports.
