Troubleshooting Ethernet Hubs
The Sun StorEdge 3900 and 6900 series uses an Ethernet hub as the backbone for the
internal service network. The allocation of Ethernet ports is as follows:
■ One for the Storage Service Processor (per subsystem)
■ One for each FC switch
■ One for each virtualization engine
■ Two for each Sun StorEdge T3+ array partner group
■ One for the Ethernet hub that is installed on the second Sun StorEdge Expansion
Cabinet in the Sun StorEdge 3960 and 6960 series systems
