摘要： A Transfer Progress Alert Module and a method for optimizing processing of a data transfer load, in a data communication system is provided. The data transfer load is divided in individual data blocks. The device and method simultaneously perform pipelined operations on different individual data blocks, thus optimizing the overlap of pipelined operations. The method includes initializing the transfer by selecting a pre-defined individual data block size and determining a key for selecting and monitoring transfers with transfer addresses within a pre-determined address region. The method then continuously repeats following steps until all monitored individual data blocks from the data transfer load are processed. First, the incoming individual data blocks are transferred on a bus between a peripheral device and a memory, and the Transfer Progress Alert module is used for monitoring the individual data blocks having transfer addresses determined to belong in the pre-determined address region. The TPA module is used to determine when each monitored transferred individual data block is ready for a post-processing operation, at least one post-processing operation is performed on the data, and the processed data is transferred to a peripheral device. The method and device may also be adapted for performing an error detection operation on the monitored individual data blocks transferred on the bus, for ascertaining the integrity of the transferred data.

摘要： A method for verifying an input/output (I/O) hardware configuration is provided. A verification command is processed. The verification command includes a software device address range associated with a logical control unit (LCU) of the I/O hardware. The LCU utilizes a first logical path. The software device address range utilizing the first logical path is compared with an existing software device address range utilizing at least one additional logical path. The verification command is accepted if the software device address range and the existing software device address range match.

摘要： An apparatus for configuring a port in a multi-port communication adapter includes a quiesce module quiescing communications at one or more first I/O ports of a multi-port communication adapter while allowing communications at one or more second I/O ports of the multi-port communication adapter. A path module removes one or more logical paths between the one or more first I/O ports and one or more remote adapters in anticipation of taking the one or more first I/O ports offline. The offline module takes offline the one or more first I/O ports. The update module updates a port resource of the one or more first I/O ports while allowing a concurrent communication on the one or more second I/O ports of the multi-port communication adapter.

摘要： Provided are techniques for determining a link speed. When a link between two computing devices is operational, a link speed for use in communicating across the link is stored and a remembered indicator is set to TRUE. After any event occurs that causes the link to become inoperational, in response to determining that the remembered indicator is TRUE, the stored link speed is used when attempting to make the link become operational.

摘要： Provided are a computer program product, system, and method for supporting non-delivery notification between a switch and device in a network. A login with a switch is initiated including a test service parameter requesting a non-delivery notification service to cause the switch to return a non-delivery notification in response to a test path request indicating a destination node that is unavailable. Indication is made that the test service is available for the login in response to receiving a reply from the switch that the switch accepts the login with the non-delivery notification service. The test path request is sent to the switch to determine whether the destination node is available in response to determining that the non-delivery notification service is available for the switch login. The non-delivery notification is received from the switch in response to the switch determining that the destination node to which the test path request is directed is unavailable.

摘要： Provided are a method, system, and article of manufacture for credit depletion notification for transmitting frames between a port pair. Credits indicate a number of outstanding frames a first device may transmit to a second device. The credits are decremented in response to transmitting a frame to the second device. The credits are incremented in response to receiving a ready code from the second device indicating that the second device processed the transmitted frame. A determination is made as to whether additional credits are needed for communicating frames from the first device to the second device. A credit depletion notification is sent to the second device in response to determining that the additional credits are needed for communication with the second device.
