The Integrated Cluster Bus for the IBM S/390 Parallel Sysplex
1999
IBM Journal of Research and Development
IBM has developed a new S/390 ® Parallel Sysplex ® coupling interface for the G5 server called the Integrated Cluster Bus (ICB). This interface improves the coupling efficiency by greatly reducing message-passing latency. Using the transport layer of the S/390 selftimed interface (STI) introduced in the G3 server, ICB adds channel function to the hub chip to allow a more direct interconnection between S/390 servers. This new channel has the same function as the present intersystem channel
