摘要： A system for managing communications to add a first Remote Direct Memory Access (RDMA) link between a TCP server and a TCP client, where the first RDMA link references first remote memory buffer (RMB) and a second RMB, and further based on a first remote direct memory access network interface card (RNIC) associated with the TCP server and a second RNIC associated with the TCP client. The system determines whether a third RNIC is enabled. The system adds a second RDMA link, responsive to a determination that the third RNIC is enabled. The system detects a failure in a failed RDMA link. The system reconfigures the first RDMA link to carry at least one TCP message of a connection formerly assigned to the failed RDMA link, responsive to detecting the failure. The system communicates at least one message of the at least one connection on the first RDMA link.

摘要： A system and computer program product for managing at least two physical links. A TCP/IP stack configures a first interface with attributes. The TCP/IP stack activates the first interface. The TCP/IP stack detects a channel path identifier (CHPID). The TCP/IP stack creates a second interface. The TCP/IP stack associates the second interface with the first interface. The first interface and the second interface are logically linked to exchange traffic corresponding to a single internet protocol address. The TCP/IP stack configures the second interface with at least one attribute. The TCP/IP stack activates the second interface. The two physical links may rely on two different physical link types.

摘要： A solution for reducing latency in a host computing device communicating with network-attached devices over a network. The host includes two network adapters that each support bidirectional communications with the host. The solution includes a dual module that represents the two network adapters as a single logical interface to both the host and the network-attached devices. An inbound module directs inbound data sent to the interface by the devices through one of the network adapters, while an outbound module directs outbound data sent to the interface by the host through the other. In one embodiment, the outbound module is responsible for intercepting data sent to the interface and sending it through the network adapter dedicated to outbound communications. The solution also includes a mode module to enable the latency reduction apparatus, and a collapse module that enables bidirectional communications through the remaining network adapter if a network adapter fails.

摘要： A data processing I/O system having a main storage for storing data including a software configuration definition and data processing instructions arranged in programs including an operating system, a storage device for storing I/O definition files including hardware configuration information, a processor controller for containing the hardware configuration information, and a hardware storage area (HSA) connected to the processor controller for storing a hardware configuration definition. A hardware configuration definition program (HCD) builds I/O definition files (IODFs), each IODF containing at least one I/O processor configuration definition. Each processor I/O configuration definition has a hardware token for identification. The hardware configuration information for an I/O processor configuration definition, along with a copy of its hardware token, is transferred to the processor controller by an I/O configuration program (IOCP), and a hardware configuration definition is established in the HSA. The copy of the hardware token may be fetched from the HSA and compared to hardware token of the configuration definition used to establish the software configuration definition in the main storage to determine that the software and hardware configuration definitions are synchronized. If the software and hardware configuration definitions are synchronized, dynamic changes may be made to the hardware configuration definition in the HSA. A program parameter is provided to store recovery information such that if a failure occurs during a dynamic change, the previous hardware I/O configuration may be recovered or subsequent changes can be made from the point of failure.
