A system and a method are proposed to minimize restriping during data center expansion. Minimal restriping technique takes into account the old data center topology, and aims to minimize restriping between the new topology and the old topology. A low complexity minimal restriping algorithm proposed is used to minimize restriping. The topology solution is also guaranteed to have high network capacity, because it satisfies superblock ports, spineblock ports,and superblock-spineblock level balancedness constraints. The constraints may consider the number of links in original topology and the algorithm may determine the optimum new topology that minimizes restriping. The disclosed technique may not cause significant bandwidth reduction, and thus greatly shortens the data center expansion time.
