摘要： A method for dynamically enabling and disabling use of XFR_RDY is disclosed herein. In one embodiment of the invention, such a method includes receiving a write command at a target and determining whether XFR_RDY is enabled or disabled for the write command. In the event XFR_RDY is disabled, the method determines whether one or more buffers are available at the target. If at least one buffer is available, the method processes the write command by writing data associated with the write command to the one or more buffers. The method then returns information indicating the number of buffers that are still available at the target after completing the write command. A corresponding apparatus and computer program product are also disclosed and claimed herein.
摘要翻译：本文公开了一种用于动态地启用和禁用XFR_RDY的方法。在本发明的一个实施例中，这种方法包括在目标处接收写入命令，并确定写入命令是否启用或禁用XFR_RDY。在XFR_RDY被禁用的情况下，该方法确定目标是否有一个或多个缓冲区可用。如果至少有一个缓冲区可用，该方法通过将与写入命令相关联的数据写入一个或多个缓冲器来处理写入命令。该方法然后在完成写命令之后返回指示目标上仍然可用的缓冲器的数量的信息。本文还公开并要求对应的装置和计算机程序产品。

摘要： A fabric login (FLOGI) in a Fiber Channel (FC) adapter is throttled. The system includes a first tracking mechanism, a second tracking mechanism, a switch, and an FC adapter. The FC adapter comprises three or more FLOGIs and a controller. First and second FLOGI requests are transmitted to the switch and indicate, via a first tracking mechanism, that a first FLOGI associated with the first FLOGI request and a second FLOGI associated with the second FLOGI request are active. A third FLOGI request is queued until the first FLOGI request or the second FLOGI request is processed by the switch and indicates, via a second tracking mechanism, that a third FLOGI associated with a third FLOGI request is queued.

摘要： A method for verifying the integrity of a communication link is disclosed herein. In selected embodiments, such a method may include detecting, during normal operation of a communication link, a condition indicative of a high failure rate (HFR) on the communication link. The method may further include placing the communication link in an HFR state as a result of the condition. While in HFR state, the method may repeatedly transmit test I/Os over the communication link. The method may then automatically exit HFR state and resume normal operation on the communication link when one or more of the following has occurred: a selected number of test I/Os have been successfully transmitted over the communication link, and a number of test I/Os have been successfully transmitted over the communication link for a selected period of time. A corresponding system, apparatus, and computer program product are also disclosed and claimed herein.
摘要翻译：本文公开了一种用于验证通信链路的完整性的方法。在所选择的实施例中，这种方法可以包括在通信链路的正常操作期间检测指示通信链路上的高故障率（HFR）的条件。该方法还可以包括作为条件的结果将通信链路置于HFR状态。在HFR状态下，该方法可以通过通信链路重复发送测试I / O。然后，当发生以下一个或多个事件时，该方法可以自动退出HFR状态并在通信链路上恢复正常操作：已经通过通信链路成功发送所选数量的测试I / O，并且多个测试I / O已经通过通信链路成功传输了一段选定的时间。本文还公开并要求对应的系统，装置和计算机程序产品。

摘要： Methods, system and computer program product are provided to configure a path between nodes through a fabric in a fibre channel storage area network (SAN). A node name is provided for a target node on the SAN and a port name is provided for each port in the target node. A relationship is established in a data structure between each port name and a slot in which each port is physically located in the target node. Prior to configuring a path between a source node and a port in the target node, the ports which are physically connected and logged in to the fabric are identified by port address. The port names corresponding to the port addresses are then identified. The port names are used to generate interface_ids of the ports corresponding to the physical slots in which the ports are located. A data structure is created to maintain the relationship between interface_ids and port names. To establish a path connection between a port in the source node and a selected port in the target node, the node name of the target node and the interface_id of the selected port are input to the data structure and the port name of the selected port is output. The port name is then used to obtain the address of the selected port and an I/O session path opened between the source and target nodes.
