摘要： Systems and methods for detecting supported small form-factor pluggable (SFP) devices in an adapter are provided. One system includes multiple ports, each port configured to be coupled to a SFP device, a tracking device configured to store data representing a list of supported SFP devices for the adapter, and a processor coupled to each of the plurality of ports and the tracking device. The processor is configured to scan each port at start-up, determine if any of the ports is coupled to a non-supported SFP device, and disable any ports that are coupled to a non-supported SFP device. One method includes scanning each port at start-up, determining if any of the ports is coupled to a non-supported SFP device, and disabling any ports that are coupled to a non-supported SFP device. Also provided are computer storage mediums including computer code for performing the above method.

摘要： An apparatus, system, and method are disclosed for handling data being communicated over lossless Ethernet that is sensitive to delays. Fiber Channel over Ethernet (FCoE) is one example of an environment where data may be subject to unacceptable delays. The method involves designating certain data as low latency data that is sensitive to delays in transmission. The low latency data is then transmitted in such a manner that the receiving devices are aware that they are receiving low latency data. If a delay in the transmission of low latency is detected, commands are issued that pause or slow standard data in order to free up bandwidth for the low latency data. The commands may be, for example, backward congestion notifications and priority flow control. Low latency data is exempted from backward congestion notifications and priority flow control. Priority 7 priority group 15 may be reserved exclusively for low latency data.
摘要翻译：公开了一种用于处理通过对延迟敏感的无损以太网传送的数据的装置，系统和方法。以太网光纤通道（FCoE）是数据可能遭受不可接受的延迟的一个例子。该方法包括将某些数据指定为对传输延迟敏感的低延迟数据。然后以这样的方式传送低延迟数据，使得接收设备知道它们正在接收低延迟数据。如果检测到低延迟传输的延迟，则发出暂停或减慢标准数据的命令，以释放低延迟数据的带宽。这些命令可以是例如反向拥塞通知和优先级流控制。低延迟数据免于后向拥塞通知和优先流控制。优先级7优先级组15可以专门用于低延迟数据。

摘要： An approach to detecting processor failure in a multi-processor environment is disclosed. The approach may include having each CPU in the system responsible for monitoring another CPU in the system. A CPUn reads a timestampn+1 created by CPUn+1 which CPUn is monitoring from a shared memory location. The CPUn reads its own timestampn and compares the two timestamps to calculate a delta value. If the delta value is above a threshold, the CPUn determines that CPUn+1 has failed and initiates error handling for the CPUs in the system. One CPU may be designated a master CPU, and be responsible for beginning the error handling process. In such embodiments, the CPUn may initiate error handling by notifying the master CPU that CPUn+1 has failed. If CPUn+1 is the master CPU, the CPUn may take additional steps to initiate error handling, and may broadcast a non-critical interrupt to all CPUs, triggering error handling.
摘要翻译：公开了一种在多处理器环境中检测处理器故障的方法。该方法可以包括使系统中的每个CPU负责监视系统中的另一个CPU。 CPUn读取CPUn + 1创建的时间戳+1，CPUn正在从共享内存位置进行监控。 CPUn读取自己的时间戳，并比较两个时间戳来计算增量值。如果增量值高于阈值，CPUn确定CPUn + 1失败，并启动系统中CPU的错误处理。一个CPU可能被指定为主CPU，并负责开始错误处理过程。在这种实施例中，CPUn可以通过通知主CPU CPUn + 1失败来启动错误处理。如果CPUn + 1是主CPU，CPUn可能会采取额外的步骤来启动错误处理，并可能会向所有CPU广播非关键中断，从而触发错误处理。

摘要： Provided are a computer program product, system, and method for updating zone information in a distributed switch of data forwarders. For each data forwarder, a sequence number is maintained for zone distribution messages sent to the data forwarder. A change to the ports in the network is detected comprising at least one of an allocation or deallocation of at least one port in the network. The sequence number for each data forwarder is incremented in response to detecting the change. For each data forwarder, a zone distribution message is generated indicating the at least one port allocated and/or deallocated, port information indicating each port in the network that may communicate with each other port, and the sequence number for the data forwarder. The generated zone distribution message is transmitted for each data forwarder to the data forwarder for which the zone distribution message was added.

摘要： A system and method for recovering from a single logical path failure. More specifically, although a host has not grouped its logical paths, the host knows which logical paths it has available. When a host detects a logical path failure, the host enters a path discovery mode of operation. If the host continues to detect a logical path failure while operating in the logical path discovery mode of operation, the host removes the logical path from a logical path mask, and the host does not use the removed logical path again. In the case of ungrouped logical paths, the host aborts its process because it does not have more paths available to continue its process. Additionally, in certain embodiments, a pseudo path group for ungrouped logical paths is created.
摘要翻译：用于从单个逻辑路径故障恢复的系统和方法。更具体地说，尽管主机没有对其逻辑路径进行分组，但主机知道其可用的逻辑路径。当主机检测到逻辑路径故障时，主机将进入路径发现操作模式。如果在逻辑路径发现操作模式下主机继续检测到逻辑路径故障，则主机从逻辑路径掩码中删除逻辑路径，并且主机不再使用已删除的逻辑路径。在未分组的逻辑路径的情况下，主机中止其进程，因为它没有更多可用的路径来继续其进程。另外，在某些实施例中，创建用于未分组的逻辑路径的伪路径组。
