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.

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.
摘要翻译：披露了技术来执行操作以促进在诸如紧耦合，多开关，多适配器，多主机分布式系统的处理环境中的PCIe交换单元的并发修复。对于要修复的识别的开关单元的操作，通过利用所识别的开关单元去除所有上游到下游连接来重新配置交换结构中的所有交换机单元硬件。通过上游端口与主机的连接也被操作删除。一旦开关单元重新接通，操作通过使用识别的开关单元添加所有上游到下游连接来重新配置交换结构中的所有交换机单元硬件。该操作进一步通过上游端口恢复到主机的连接。

The apparatus and methods may include (1) providing a system including a plurality of computers coupled via a network, wherein a first computer of the plurality of computers includes a plurality of physical adapters and at least one virtual adapter; (2) for each virtual adapter in the first computer, assigning a rank to each physical adapter in the first computer; and (3) based on the ranks, testing one or more of the physical adapters in the first computer for connectivity to a physical adapter in a second computer with which a first virtual adapter is likely to communicate. Connectivity tests are started in a staggered manner that favors highly ranked physical adapters. Numerous other aspects are provided.
