    摘要： A method and apparatus for exchanging data in a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s). A state change signalling protocol is used for transfer of data between the main storage and said adapter. In addition a queuing mechanism is established in the main storage having a plurality of queues each with a plurality of buffers. Some of these queues are dedicated to be input and others as output queues. By applying the protocol each input and output data buffer is associated with each of the active input and output queues. In this manner the input and output buffers are managed by placing the buffers into various states which are maintained in a special location that is set aside and is associated with each buffer. After complete transmission of data, the state of each such buffer is changed in order to make it buffer available for reuse.

    摘要： A method of providing direct data processing access in a network computing system environment. The system environment has a main storage which can be connected to one or more application servers and is in processing communication with an interface element. The interface element has at least one adapter and can be connected to one or more application user(s). One or more queues are established in the main storage that can handle data without causing interrupts in the running programs. Incoming data is received using the adapter and as data is received or modified, the status of the network computing system will be updated to reflect the new data or change. Data is then processed in the main storage after interrogating the multiple existing queues in the main storage and forwarding them in turn to their appropriate destination or application server after a determination has been made by interrogating these queues.

    摘要： In a computing network system environment having a gateway device that is electronically connected from one side to a plurality of initiating hosts and on another side to at least one local area network, in turn connecting a plurality of hosts are connected to the gateway device, a method and apparatus for eliminating any need for building a separate and special protocol data unit element for each header. The computer network environment uses a Multi-path channel communication protocol as well as protocol data units to point to various portions of data. An interface layer is provided between a plurality of protocol stacks and the multi-path channel protocol. The interface layer has a timer which will wait for data from the protocol stack. A list of all buffers are assembled as received comprising of one entry for each data buffer. This buffer list is then transferred to the multi-path channel protocol layer upon expiration of the timer, which is in turn sent to any channel attached processor as one block. A deblocker interface is also provided on all channel attached processors so that any length fields provided in the protocol headers can be used to determine offset of next data element in said block and thus eliminating need for a special header at next data element used by the communication protocol.

    摘要： Apparatus, method and program product for use in passing initiative to a processor for handling an I/O request for an I/O operation for sending data between a main storage and one or more devices. A hierarchy of vectors registers I/O requests by the devices to send or receive data from the main storage. The hierarchy of vectors has one or more lower levels and a highest level. Each device sets a vector in the lowest level of the hierarchy for registering an I/O request, the setting of a vector in the lowest level being reflected up the hierarchy to the highest level, thereby registering I/O requests on any lower level of the hierarchy in the highest level. A dispatcher polls the hierarchy in high to low order with the dispatcher passing initiative to the processor to handle I/O requests registered in said hierarchy responsive to registering of an I/O request on the lowest level as reflected to the highest level of said hierarchy.

    摘要： An apparatus, method and program product for sending data to or receiving data from one or more I/O devices in an I/O operation with a main storage controlled by a processor in a data processing system. The apparatus includes a time-of-day (TOD) register for containing a TOD value, a clock for containing a current TOD value, and a summary register having a first condition when any one of said devices requests an I/O operation and a second condition when no devices have an outstanding I/O request, each device having an outstanding I/O request sets the summary register to its first condition only when the summary register is in its second condition, and further places the current TOD value in the TOD register. A checking program determines if a specified time delay has been exceeded between the value in said TOD register and the current TOD for each requested I/O operation. The checking program drives an interrupt to the processor when the specified time delay has been exceeded.

    摘要： A method, system, program product and computer data structure for providing for two levels of server virtualization. A first hypervisor enables multiple logical partitions to share a set of resources and provides a first level of virtualization. A second hypervisor enables multiple, independent virtual machines to share the resources that are assigned to a single logical partition and provides a second level of virtualization. All events for all of the virtual machines within said single logical partition are grouped into a single partition-owned event queue for receiving event notifications from the shared resources for that single logical partition. A request for an interrupt is signaled for the grouped events from the partition-owned event queue for the demultiplexing of grouped events, by the machine, from the partition-owned event queue into individual, virtualized event queues that are allocated on a per virtual machine basis.

    摘要： A method for configuring a communication port of a communications interface of an information handling system into a plurality of virtual ports. A first command is issued to obtain information indicating a number of images of virtual ports supportable by the communications interface. A second command is then issued requesting the communications interface to virtualize the communication port. In response to the second command, one or more virtual switches are then configured to connect to the communication port, each virtual switch including a plurality of virtual ports, such that the one or more virtual switches are configured in a manner sufficient to support the number of images of virtual ports indicated by the obtained information. Thereafter, upon request via issuance of a third command, a logical link is established between one of the virtual ports of one of the virtual switches and a communicating element of the information handling system.
