Connector for adjacent devices
View Patent ↗An apparatus and method for connecting servers within a rack-mounted server system. In one embodiment, a plurality of servers are positioned in respective bays of a rack. The bays generally constrain adjacent servers in a generally fixed spacing and in face-to-face alignment. A first server is moved within its bay relative to a second server until a connector on the first server is aligned with a mating connector on the second server. Alignment of the two mating connectors is detected by a position sensor, such as an LED-photodiode pair. A signal from the position sensor causes or at least allows the first and second connectors to be moved toward one another, either using a motor or a hand-actuated mechanism, to provide power and data communication between the servers. Once the connection is established, data is optionally transmitted via the optical sensor.
1. A computer program product embodied on a computer-readable medium providing computer useable program code for connecting adjacent servers, comprising:
computer usable program code for determining that a first connector of a first server in a first rack bay is aligned with a second connector of a second server in a second rack bay adjacent to the first rack bay; and
computer usable program code for controlling an actuator to selectively extend at least one of the first and second connectors to establish electrical communication between the first and second connectors in response to determining alignment of the first and second connectors.
2. The computer program product of claim 1 , wherein the computer usable program code for determining alignment of the first and second connectors includes computer usable program code for receiving a signal from a photodiode on the first server when the photodiode is aligned with an LED on the second server.
3. The computer program product of claim 1 , further comprising:
computer usable program code for transmitting data optically between the first and second servers.
4. The computer program product of claim 1 , wherein the actuator includes an electric motor.
5. The computer program product of claim 1 , further comprising:
computer usable program code for receiving a signal to retract an extended connector and disconnect the first and second connectors; and
computer usable program code for shutting down communications between the first and second servers over the first and second connectors prior to retracting the extended connector.
6. The computer program product of claim 5 , further comprising:
computer usable program code for controlling the actuator to selectively retract an extended connector and disconnect electrical communication between the first and second connectors in response to shutting down communications between the first and second servers.
7. The computer program product of claim 5 , wherein the signal to retract an extended connector is initiated by entering a software command.
8. The computer program product of claim 5 , wherein the signal to retract an extended connector is initiated by a user pressing a button or switch provided on the rack, the first server or the second server.
9. The computer program product of claim 5 , wherein the computer usable program code for shutting down communications between the first and second servers over the first and second connectors includes computer usable program code for shutting down any software currently utilizing the first and second connectors.
