A dual host system and method with back to back non-transparent bridges and a proxy packet generating mechanism. The proxy packet generating mechanism enables the hosts to send interrupt generating packets to each other.

Method and apparatus to facilitate system to system protocol exchange in back to back non-transparent bridges

An endpoint node on a switch fabric announces an intent to host a service for the switch fabric. The announcement includes an announcement entry to an announcement record in a data repository maintained at a designated endpoint node on the switch fabric. The announcement entry includes the endpoint node's preference to take a given role to host the service. The endpoint node queries the announcement record to determine what other endpoint nodes have announced an intent to host the service. Based, at least in part, on the query, the endpoint node determines a role it will take to host the service. The endpoint node updates the announcement record to indicate the role.

Switch fabric service hosting

Embodiments are generally direct to a method and apparatus to generate a data descriptor. In one embodiment, a data descriptor is generated for a block of data to be forwarded from a node to another node on a communication link. The data descriptor includes an indication to build a data packet containing at least a portion of the block of data in an accelerated or a non-accelerated manner.

Method and apparatus to generate a data descriptor

Methods and systems, including computer program products, implementing techniques for receiving, at a first device of a switched fabric network, requests from one or more applications, each request being destined for a second device of the network, the first device being connected to the second device by a virtual channel; generating, for each request, a descriptor comprising a traffic class designation; and adding the descriptor to an ordered list of descriptors, the descriptor having a location in the ordered list that is based on the traffic class designation of the descriptor.

Simulating multiple virtual channels in switched fabric networks

An apparatus communicates with an advanced switching (AS) fabric. The apparatus includes a transmit engine that generates a request packet for transmission to the AS fabric. The transmit engine associates a first transaction identifier with the request packet. A receive engine receives a reply packet in response to the request packet. The reply packet contains a second transaction identifier. The receive engine compares the first transaction identifier to the second transaction identifier. If the first transaction identifier matches the second transaction identifier, the receive engine decides to store data from the reply packet at an address associated with the first transaction identifier.

Processing replies to request packets in an advanced switching context

Disclosed are a system and method of remotely providing diagnostic procedures to a processing system. Upon being launched on a processing system, an agent process may receive data to provide one or more diagnostic procedures from a data network coupled to the processing system. One or more of the diagnostic procedures may then be executed to provide diagnostic results.

Remote diagnostics system

A system and method of using of diagnostic procedures through a firmware interface in a processing system are described. A first physical area of a memory may store one or more diagnostic modules comprising machine-readable instructions for performing one or more diagnostic procedures of a processing system. A second physical area of the memory may store an operating system capable of initiating execution of the one or more diagnostic procedures through the firmware interface.

Operating system independent

An operating system may be more efficiently initiated and restarted by making a virtual image of the configuration settings for a base system configuration. These settings may be stored and may be used to quickly initiate the system in its base configuration, for example, using an executive. The base configuration may be automatically modified in response to system hardware or software configuration changes. These changes may be stored with the base configuration information. When a crash occurs, the virtual image may be used to quickly restore the system without the necessity for rebooting the operating system.

Initializing and restarting operating systems

A method and apparatus for managing power consumption in a computer system wherein the method and apparatus is compliant with the proposed Advanced Configuration and Power Interface (ACPI) specification. In one embodiment, a power management processor is sandwiched between platform hardware and the ACPI register layer. The processor processes all operating power management commands and requests while remaining transparent to the user and the operating system. In so doing, routine power management functions, so classified by the operating system, are implemented by the operating system. Sophisticated power management features, on the other hand, are implemented by the present invention independent from operating system control. Accordingly, in the present invention, the operating system need not suspend processing of other threads to process sophisticated power management procedures.
