Abstract: A server interconnection system includes three switches each having n downlink ports and an uplink port, wherein n is an integer equal to or larger than 2; and m servers each having at least two network interface cards respectively connected to downlink ports of different switches, wherein m=3p/2, p is an even number equal to or larger than 2 but equal to or less than n, wherein every three servers form a group. A first server connects to a downlink port of a first switch and a downlink port of a second switch via two network interface cards. A second server connects to a downlink port of the first switch and a downlink port of a third switch via two network interface cards. A third server connects to a downlink port of the second switch and a downlink port of the third switch via two network interface cards.
