An expander controller for a dual ported bus interface comprises a controller coupled to the dual ported bus interface. The dual ported bus interface has first and second front end ports capable of connecting to host bus adapters, and first and second isolator/expanders coupled to the first and second front end ports. The bus interface also has first and second backplane connectors for insertion into a selected slot of first and second slots and coupling to one or more buses on the backplane. The bus interface further includes interconnections for coupling signals from the first and second front end ports through the isolator/expanders to the backplane buses. The expander controller further includes a programmable code executable on the controller and further comprising a programmable code that detects interface status, bus configuration, and selected slot; and a programmable code that controls operations of the isolator/expanders based on the detected interface status, bus configuration, and selected slot.
