A method for management of a host computer that includes a management controller configured to carry out, independently of the host CPU, host management instructions contained in management packets compliant with a first data link protocol. The method includes receiving the management packets from a first network operating in accordance with the first data link protocol. The management packets are encapsulated in data packets compliant with a second data link protocol, different from the first data link protocol. The data packets are transmitted to a second network, operating in accordance with the second data link protocol. The transmitted data packets are received from the second network in a network interface controller (NIC), which is installed in the host computer and connected to the second network. The NIC decapsulates the management packets from the received data packets and passes the decapsulated management packets via a sideband connection to the management controller.

Remote host management over a network

A startup sequence in a computer system is initiated by detecting a bus reset event in an I/O device connected to a host, and responsively to the bus reset event communicating resources required to be allocated by the host. When a startup command from a host driver is not received within a predetermined bus reset count, the device autonomously changes its current configuration to a safe mode configuration, wherein fewer resources are required to be allocated relative to the current configuration. The safe mode configuration is communicated from the device to the host.
