Cable Reduction Technology Utilizing Power Line Networking for Server Management

Disclosed is a method that uses Power Line Networking (PLN) for communicating with a Baseboard Management Controller (BMC) for server management activities. Benefits include a solution that uses no network bandwidth and improves security.

Background

Currently, cable-reduction technology is used with many servers; one of these cable reduction techniques is the TCO for server management. Many servers come equipped with a BMC, which can be used for server management via a TCO port over a LAN connection. The TCO port is part of a specialized NIC on the motherboard. The TCO enabled NICs allow the BMC to share bandwidth with the OS for server management traffic; all UDP network traffic with a destination of port 623 is routed to the BMC via the TCO port. There is a simple bus mechanism connecting the NIC to the BMC enabling this communication.

However, the TCO method of server management requires some bandwidth that the OS could be using. Some customers choose not to use this mechanism for server management because they require all the network bandwidth possible. Also, customers are concerned about security when the TCO port is enabled. The current security within the Intelligent Platform Management Interface (IPMI) 1.5 is inadequate, and therefore many choose not to use the TCO port for server management.
