摘要： A method for managing storage space in a storage port queue includes establishing a watermark for the storage port queue. The method further receives, at the storage port associated with the storage port queue, a command having an initiator-target-LUN (ITL) nexus associated therewith. Upon receiving the command, the method determines whether the used space in the storage port queue has reached the watermark. In the event the used space has not reached the watermark, the method processes the command. In the event the used space has reached the watermark and a specified number of commands for the ITL nexus are already present in the storage port queue, the method rejects the command. Otherwise, the method may process the command.

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： An computer program product, apparatus, and method for facilitating input/output (I/O) processing for an I/O operation at a host computer system configured for communication with a control unit. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes the host computer system obtaining a transport command word (TCW) for an I/O operation. The TCW specifies a location of one or more I/O commands and a flag. The flag is set to indicate that the location is an indirect address. The host computer system extracts the location of the one or more I/O commands and the flag from the TCW. The host computer system gathers the one or more I/O commands responsive to the location specified by the TCW and the flag, and then forwards the one or more I/O commands to the control unit for execution.

摘要： An article of manufacture, apparatus, and a method for facilitating input/output (I/O) processing for an I/O operation at a host computer system configured for communication with a control unit. The method includes the host computer system obtaining a transport command word (TCW) for an I/O operation having both input and output data. The TCW specifies a location of the output data and a location for storing the input data. The host computer system forwards the I/O operation to the control unit for execution. The host computer system gathers the output data responsive to the location of the output data specified by the TCW, and then forwards the output data to the control unit for use in the execution of the I/O operation. The host computer system receives the input data from the control unit and stores the input data at the location specified by the TCW.

摘要： An apparatus, system, and method are disclosed for determining the location of intermediate CRC in a data stream sent from a channel subsystem to a control unit of an I/O processing system. A CRC locating module determines the location of at least one intermediate CRC in a transport data information unit. A CRC offset module determines a CRC offset of the at least one intermediate CRC. The CRC offset is a value identifying the difference between the location of the at least one intermediate CRC and the location of the first byte of user data in the transport data information unit. An offset block creation module creates a CRC offset block which includes a CRC offset value for each of the at least one intermediate CRC within the transport data information unit and a transmission module transmits the COB to a control unit in the I/O processing system.
