The buffering of RSCN frames is disclosed so that RSCN traffic can be reduced. At the start of a state change notification period, a timer is started. A state change manager buffers state changes in a register that holds a pending RSCN frame by storing the address of each changed device. When a new state change is received, the address of the corresponding device is compared against each of the addresses currently stored in the buffered RSCN frame. If a duplicate address is found, the searching process ends. If no duplicate address is found, then the new address is added to the next available 32-bit field in the buffered RSCN frame. When a specified number of state changes have been received, or a specified amount of time has elapsed, the RSCN frame is sent to each initiator that had previously registered to receive state changes.
