US Patent:

6829660, Dec 7, 2004

Filed:

Dec 10, 2002

Appl. No.:

10/316604

Inventors:

Michael Liu - Alhambra CA
Bradley Roach - Newport Beach CA
Sam Su - Irvine CA
Peter Fiacco - Yorba Linda CA

Assignee:

Emulex Design Manufacturing Corporation - Costa Mesa CA

International Classification:

G06F 1328

US Classification:

710 22, 710 38, 710305, 709212

Abstract:

A system with a first random access memory (RAM), a second RAM, a first processor coupled to the first RAM and a second processor coupled to the second RAM. The first RAM is configured to store input/output (I/O) completions from atleast two engines. The second RAM is also configured to store I/O completions from at least two engines. When all engines are active, the system writes I/O completions from the engines to the first and second RAMs. The first processor processes I/O completions stored in the first RAM. The second processor processes I/O completions stored in the second RAM.

International Classification:

G06F 15/00

US Classification:

700299, 710 10, 702132, 713300, 709221

Abstract:

Embodiments of the present invention are directed to systems and methods for controlling the temperature of an internal device while reducing or minimizing the involvement of the host. Thus, some of the heat monitoring and remediation work may be offloaded to the actual device itself. The device may monitor its own temperature and, in the event of high temperature, perform device specific heat reduction actions without involving the host. Furthermore, the device may, upon detecting temperature within a predefined range, alert the host of a high temperature condition in order to allow the host to perform temperature reduction measures. Also, the device may, upon detecting temperature within a predefined range, alert the host of an impending device shutdown and shut the device down. In addition, the device may periodically save its temperature into non-volatile memory in order to create a temperature log.

US Classification:

Abstract:

A network arbitration scheme is disclosed that manages device access fairness by selectively and dynamically increasing a requestor queue's likelihood of being serviced. A requestor queue increases its service priority by duplicating a request entry onto a set of priority rings maintained by arbitration hardware in a host bus adapter. Duplication occurs when (1) a requestor's queue fill count (the number of descriptors stored in the queue) exceeds a watermark level or (2) a requestor's queue timer times out. In the case of time-out, the requester in the lower priority ring will duplicate itself in the higher priority ring. Because the arbitration hardware services requesters using a round robin selection scheme, the likelihood of a requestor queue being serviced increases as the number of its duplicate request entries on a priority ring increases. Upon being serviced, the requester is able to perform the requested action.
