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： Method and apparatus for sending data from one partition to a second partition within a logically partitioned computer. In a data processing system having multiple logical partitions, a send queue is established in the first logical partition, and a receive queue is established in the second logical partition. The send queue is registered in the send queue in a lookup table available to all of the logical partitions. The send queue is registered using as a key the logical partition identification of the first logical partition and the subchannel number (LPAR-ID.SUBCHANNEL#) of the subchannel assigned to the partition. The receive queue is registered in the lookup table using as a key, the internet protocol address of the receive queue in the second partition. A send instruction from the first logical partition is executed which interrogates the lookup table using the LPAR-ID.SUBCHANNEL# key to locate the send queue and IP address key to locate the receive queue, and sends the data in the send queue in the first logical partition to the receive queue in the second logical partition. This method and apparatus provides that discrete servers may be used in each logical partition, and data may be transferred between while maintaining security between the logical partitions.

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： 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 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 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.

摘要： The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.
