split-star topology

A network

topology

that uses up to two HP NonStop Cluster Switches for each external

fabric. External routing is implemented between the two starred halves of a ServerNet
cluster. (A starred half consists of up to eight nodes attached to one set of cluster
switches.) The starred segments are joined by four-lane links. The split-star topology
supports up to 16 nodes.
