摘要： A method for performing a data exchange between an initiator and a receiver in a fiber channel protocol (FCP) is provided. A control flag is set in a write command to indicate the presence of an identifier. The identifier is copied into a command descriptor block (CDB) of the write command and appended to a data frame. The write command and data frame, including the identifier, is sent from the initiator to the receiver.

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 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：所选择的测试I / O数量已经通过通信链路成功发送，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。
