摘要： Systems and methods to perform a register access are described. A particular method includes receiving a data frame at a bridge element of a plurality of bridge elements in communication with a plurality of server computers. The data frame may include a register access request and may be forwarded from a controlling bridge in communication with the plurality of bridge elements. A register may be accessed and execution of the register access request may be initiated in response to receiving the data frame.

摘要： Techniques are disclosed to reduce crossover between traffic from switch elements of different switch domains in a distributed switch. Addition of a first switch element to the distributed switch is detected. The distributed switch includes multiple switch elements at least subsequent to the addition, and each switch element has a switch element identifier and a fabric identifier. The respective fabric identifiers of the first switch element and of a second switch element are retrieved. The second switch element is communicably connected to the first switch element via a link, and the link is configured to allow only command traffic to be transmitted via the link. Upon a determination that the fabric identifier of the first switch element does not match the fabric identifier of the second switch element, then no command is issued specifying to reconfigure the link to allow at least one additional traffic type, different from command traffic.

摘要： Techniques are disclosed for reducing impact of a switch failure and/or a repair action in a switch fabric. In one embodiment, a server system is provided that includes a first interposer card that operatively connects one or more server cards to a midplane. The first interposer card may include a switch module that switches network traffic for the one or more server cards. The first interposer card may be hot-swappable from the midplane, and the one or more server cards may be hot-swappable from the first interposer card. The server system may further include an interconnect between the first interposer card and a second interposer card.

摘要： Techniques are disclosed to perform an operation to facilitate concurrent repair of PCIe switch units in processing environments such as a tightly coupled, multi-switch, multi-adapter, multi-host distributed system. The operation, for an identified switch unit to be repaired, reconfigures all switch unit hardware in the switch fabric by removing all upstream to downstream connections utilizing the identified switch unit. Connections to hosts via the upstream ports are also removed by the operation. Once the switch unit is powered back on, the operation reconfigures all switch unit hardware in the switch fabric by adding all upstream to downstream connections utilizing the identified switch unit. The operation further restores connections to hosts via the upstream ports.

摘要： Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer and at least one packet interface. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis and bifurcation layer analyzes the packet and sends the packet to the packet interface, which then routes the packet to the first application.
