Abstract
A mechanism is provided for storage enclosures to communicate with one another using pre-existing cables allowing the user to dynamically attach different types and speeds of Fiber Channel enclosures together. The mechanism uses a transmit disable line and receive loss of signal line of a small form-factor pluggable optical cable to provide a communication link between enclosures before the Fiber Channel loop is setup and stable. The mechanism on the transmit side pulses the transmit disable line to communicate configuration information. The mechanism on the receive side receives the configuration information on the receive loss of signal line. The transmit disable line and the receive loss of signal line operate as a one-wire communication scheme, providing a communication link to communicate configuration information before the Fiber Channel loop is established.
