Digital rack interface pod system and method
View Patent ↗A digital rack interface pod (DRIP) that is able to establish a communications link between a remote access appliance and a server having a USB port and a video port, to facilitate a keyboard/video/mouse (KVM) session between the server and the appliance. The DRIP is also able to establish a communications link between the appliance and an Ethernet port of the server that is associated with a service processor (SP) of the server. In this manner the DRIP is able to route data from the SP of the server to the appliance as well as communications from the appliance to the SP Ethernet port of the server. The DRIP is able to intelligently determine which packets of information received from the appliance are intended for the SP Ethernet port of the server and routes those packets to the SP Ethernet port of the server. The DRIP also automatically monitors and dynamically reassigns its two Ethernet ports as needed so that whichever one of its two Ethernet ports it discovers a connection with the appliance on will be the port that it continues using to communicate with the appliance.

11. The apparatus of claim 1 , further comprising a double data rate (DDR) memory in communication with the circuit.
12. A standalone digital rack interface pod (DRIP) apparatus adapted to facilitate communications between a remote access appliance and a server having a service processor, the apparatus comprising:
a housing;
a first Ethernet port and a second Ethernet port disposed in the housing, the first Ethernet port adapted to enable a first communications cable to be coupled thereto to enable a connection to be made to an appliance, and the second Ethernet port adapted to enable a second communications cable to be coupled thereto to enable a connection to be made with a service processor port of the server;
a cable assembly extending from the housing for enabling the apparatus to be removably coupled to a video port and to a universal serial bus (USB) port of the server; and
a circuit disposed in the housing and being in communication with at least the first and second Ethernet ports, and configured to detect the reception of Ethernet packets from the appliance which are directed to either of the first and second Ethernet ports, and to automatically route ones of the detected Ethernet packets needing to be delivered to the service processor of the server to the second one of the Ethernet ports, and to route a remainder of the detected Ethernet packets to the USB port of the cable assembly.
13. The apparatus of claim 12 , further comprising a USB hub in communication with the circuit, for interfacing the circuit with the USB port of the server.
14. The apparatus of claim 12 , wherein the circuit comprises an application specific integrated circuit (ASIC).
15. The apparatus of claim 14 , wherein the ASIC continuously, alternately monitors the first and second Ethernet ports when the apparatus is initially connected to the appliance, and detects which of the first and second Ethernet ports initially receives Ethernet packets having a MAC address that matches a MAC address assigned to the apparatus, and subsequently sets the one of the first and second Ethernet ports that initially receives the Ethernet packets with a MAC address matching the MAC address of the device as the port that is to be treated as the Ethernet port in communication with the appliance.
16. The apparatus of claim 15 , wherein the ASIC detects which said ones of the received Ethernet packets have a MAC address that does not match the MAC address assigned to the apparatus, and routes said ones of the Ethernet packets that have a MAC address that does not match the MAC address of the apparatus to the one of the Ethernet ports that is coupled to the second cable, to thus route said ones of the Ethernet packets to the service processor of the server.
17. The apparatus of claim 14 , wherein the ASIC continuously, alternately monitors the first and second Ethernet ports each for a predetermined time period.
