Fibre channel architecture port having optical and copper connectors
View Patent ↗First and second inputs are associated with a port. Logic produces indications to software to cause the first input and second input to appear as a single input to the software. The logic produces an indication that no signal is present on either the first input or the second input. When a port bypass controller is coupled to the port, the logic produces an indication that both the first and second inputs are bypassed. When the port bypass controller is coupled to a Fibre Channel arbitrated loop, the logic produces a first signal to control whether the first input is included on the Fibre Channel arbitrated loop or bypassed, and a second signal to control whether the second input is included in the Fibre Channel arbitrated loop or bypassed.
1. Apparatus comprising:
a first input associated with a port;
a second input associated with the port; and
logic for producing indications to software to cause the first input and second input to appear as a single input to the software, including logic operable to select only one of the first and second inputs for communication with the software at a given point in time, wherein the logic produces an indication that no signal is present on either the first input or the second input.
2. The apparatus of claim 1 wherein a port bypass controller is coupled to the port, and wherein the logic produces an indication that both the first and second inputs are bypassed.
3. The apparatus of claim 2 wherein the port bypass controller is coupled to a Fibre Channel arbitrated loop.
4. The apparatus of claim 3 wherein the logic produces a first signal to control whether the first input is included on the Fibre Channel arbitrated loop or bypassed, and a second signal to control whether the second input is included in the Fibre Channel arbitrated loop or bypassed.
5. Apparatus comprising:
a port bypass controller;
first and second connectors coupled to the port bypass controller;
a first loss of signal indicator indicating whether a signal exists on the first connector;
a second loss of signal indicator indicating whether a signal exists on the second connector;
logic for producing:
a first bypass signal responsive to the first loss of signal indicator, the first bypass signal input to the port bypass controller for controlling whether the first connector is coupled to a Fibre Channel arbitrated loop or bypassed;
a second bypass signal responsive to the second loss of signal indicator, the second bypass signal input to the port bypass controller for controlling whether the second connector is coupled to a Fibre Channel arbitrated loop or bypassed;
a port loss of signal indicator responsive to the first loss of signal indicator and the second loss of signal indicator, the port of loss of signal indicator indicating to software that no signal is input to the port bypass controller from either connector; and
a port bypass signal responsive to the first bypass signal and the second bypass signal, the port bypass signal indicating to software that both connectors are bypassed.
6. A method comprising the steps of;
providing a first input associated with a port;
providing a second input associated with the port; and
producing indications to software to cause the first input and second input to appear as a single input to the software, including selecting only one of the first and second inputs for communication with the software at a given point in time, wherein the step of producing produces an indication that no signal is present on either the first input or the second input.
7. The method of claim 6 further comprising the step of coupling a port bypass controller to the port, and wherein the step of producing produces an indication that both the first and second inputs are bypassed.
8. The method of claim 7 further comprising the step of coupling the port bypass controller to a Fibre Channel arbitrated loop.
9. The method of claim 8 wherein the step of producing produces a first signal to control whether the first input is included on the Fibre Channel arbitrated loop or bypassed, and a second signal to control whether the second input is included in the Fibre Channel arbitrated loop or bypassed.
10. A method comprising the steps of:
coupling first and second connectors to a port bypass controller;
providing a first loss of signal indicator indicating whether a signal exists on the first connector;
providing a second loss of signal indicating whether a signal exists on the second connector;
producing:
a first bypass signal responsive to the first loss of signal indicator, the first bypass signal input to the port bypass controller for controlling whether the first connector is coupled to a Fibre Channel arbitrated loop or bypassed;
a second bypass signal responsive to the first loss of signal indicator, the second bypass signal input to the port bypass controller for controlling whether the second connector is coupled to a Fibre Channel arbitrated loop or bypassed;
a port loss of signal indicator responsive to the first loss of signal indicator and the second loss of signal indicator, the port loss of signal indicator indicating to software that no signal is input to the port bypass controller from either connector;
a port bypass signal responsive to the first bypass signal and the second bypass signal, the port bypass signal indicating to software that both connectors are bypassed.
