Abstract: A method for processing inbound and/or outbound data wherein a processing policy is determined for a quantum of data. A quantum of inbound data is received and a data notification for the received data is prepared. The notification for the quantum of received inbound data is delivered to a processor according to the processing policy. When selecting a quantum of outbound data, an outbound data work request for the outbound data is prepared and delivered to an output unit according to the processing policy.

Abstract: A cooling system for a blade enclosure is disclosed. The cooling system comprises a thermal bus bar (TBB) 1220 positioned in the middle of the blade enclosure. The TBB 122 has a front face and a back face. When blades are inserted into the blade enclosure, a heat transfer plate 584 on the blade makes thermal contact with either the front or back face of the TBB 122. The TBB 122 is cooled, thereby cooling the blades.

Abstract: A cooling system for a computer blade is disclosed. The cooling system comprises a main printed circuit (PC) board with at least one component mounted on a top side of the main PC board. A heat transfer plate is located at the first end of the main PC board. An airflow divider is mounted on, and is perpendicular with, the top side of the main PC board. The airflow divider runs in an axis generally parallel with the first side of the main PC board. A lid is coupled to the main PC board thereby enclosing the main PC board, the heat transfer plate and the airflow divider. The lid encloses a first airflow channel running along the first side of the main PC board and a second airflow channel running along the second side of the main PC board. A fan is located on top side of the main PC board in the first airflow channel. The fan is configured to re-circulate air from the second airflow channel through the first airflow channel, past the heat transfer plate, and then back into the second airflow channel.

Abstract: A method includes producing units of work with at least one source application instance (AI) at a source device and consuming units of work with at least one destination AI at a destination device. A first reliable datagram service is established, with a first source and destination resource (SDR), between the source device and the destination device. A second reliable datagram service is established, with a second SDR independent of the first SDR, between the source device and the destination device. A first unit of work stream is transmitted over a communication services/fabric with the first reliable datagram service, which guarantees strong ordering of the first unit of work stream received at the destination device. A second unit of work stream is transmitted over the communication services/fabric with the second reliable datagram service, which guarantees strong ordering of the second unit of work stream received at the destination device.

Abstract: A reliable multicast service is operated between a source device and multiple destination devices participating in a multicast group. The source device includes a first source application instance (AI) producing a first unit of work stream, and communication services (CS). Each destination device in the multicast group includes CS, and at least one destination AI which consumes units of work. Communication services/fabric provide communication between the source device and the multiple destination devices. Multiple source and destination resources (SDRs) implement corresponding multiple reliable transport services between the source device and corresponding multiple destination devices in the multicast group for delivery of the first unit of work stream to the corresponding destination devices and guaranteeing strong ordering of the first unit of work stream received at the corresponding destination devices.

Abstract: A reliable datagram service is implemented with a source and destination resource (SDR). Source SDR resources, at a source device, multiplex units of work produced by at least one source application instance (AI) into a serial unit of work stream having units of work in a defined order and transmit the serial unit of work stream over a communication services/fabric. Destination SDR resources, at a destination device, receive the serial unit of work stream, demultiplex the serial unit of work stream into units of work provided to at least one destination AI, and provide a negative acknowledgement (NAK) for a unit of work received ahead of its defined order.

Abstract: The present invention relates to highly available sequence number generation with minimal latency. The present invention involves establishing a primary and secondary sequence number generators. A sequence number request is forwarded to the primary generator. The primary generator determines the next sequence number and forwards the response to the secondary generator. The secondary generator stores the value and forwards the value to the originating entity. Accordingly, the configuration avoids single point failure and is robust against malfunction.
