摘要： An apparatus, system, and method are disclosed for handling data being communicated over lossless Ethernet that is sensitive to delays. Fibre 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： A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.

摘要： A system for providing hosts with a capability to determine which threshold rule of a plurality of threshold rules to use based upon threshold consensus. For example, the system would address a configuration case of several hosts sharing an output port of a fabric via zoning and that port being connected to a single port of a storage controller. If one host is executing lower priority jobs and its threshold is much higher than another host with higher priority jobs and a lower threshold, and the storage controller recognizes that several hosts are sharing the same storage controller port, the consensus will be to ignore the threshold of the first host and to use the threshold of the second host to prevent performance degradation in the system.
摘要翻译：一种用于向主机提供基于阈值共识来确定要使用的多个阈值规则的哪个阈值规则的能力的系统。例如，系统将通过分区和该端口连接到存储控制器的单个端口来解决几个主机共享结构输出端口的配置情况。如果一个主机正在执行较低优先级的作业，并且其阈值远高于具有较高优先级作业和较低阈值的另一个主机，并且存储控制器识别出若干主机正在共享相同的存储控制器端口，则共识将忽略阈值并使用第二个主机的阈值来防止系统中的性能下降。

摘要： A network system supports multiple network communication protocols. An Ethernet component gateway in a Fibre Channel over Ethernet (FCoE) initiator system converts FCoE data packets from host devices to Fibre Channel over Internet Protocol (FCIP) data packets for transmission to a Storage Area Network (SAN) target system. The SAN target system may include a target Fibre Channel (FC) storage device and a SAN component gateway. The SAN component gateway converts FCIP data packets to SAN data packets for use by the target FC storage device. The SAN data packets may be either FC protocol data packets or FCoE protocol data packets. The SAN target system may provide for discovery of target FC storage device adapter information.

摘要： A system for using a virtual switch in a network. In response to a switch connecting to a network, network configuration data is read to determine whether the switch is part of a virtual switch. In response to determining that the switch is part of the virtual switch, a priority number for the switch is sent to other switches connected to the network. Priority numbers are received from the other switches. It is determined whether the switch has a highest priority number. In response to determining that the switch does have the highest priority number, the switch is selected to be a master switch for the virtual switch. Then, domain identification data for the virtual switch is sent to the other switches. Afterward, the switch and the other switches respond to requests over the network as one domain identified by the domain identification data.
