The HP-UX Fabric Clustering System interconnect solution scales without adversely affecting the service demand
requirements on the server. Because of lack of dual rope slots on rx4640, HCA scaling was tested only up to 2
HCAs.
HP Fabric Clustering System – Switch Fabric
HP-UX Fabric Clustering System Interconnect solution can be used to build multi-node clusters using these switches. The
AB291A – 12-port 4X Switch is used in testing the switch configurations. The following switch configurations were
used for testing the performance characteristics:
•
