20080243465 | FACILITATING INPUT/OUTPUT PROCESSING OF ONE OR MORE GUEST PROCESSING SYSTEMS - An article of manufacture, method and system are provided for facilitating input/output (I/O) processing of at least one guest processing system. The article of manufacture includes at least one computer-usable medium having computer-readable program code logic to facilitate the I/O processing of the at least one guest processing system. The computer-readable program code logic when executing performing the following: emulating on a native system an I/O architecture for the at least one guest processing system, the emulating including: providing multiple device managers for a plurality of I/O devices of the I/O architecture; providing at least one communications adapter process interfacing the multiple device managers to the at least one network driver process; and wherein the multiple device managers translate I/O messages in at least one guest processing system format to messages in native system format for processing by the at least one communications adapter process, thereby facilitating I/O processing. | 10-02-2008 |
20080243467 | EMULATED Z-SERIES QUEUED DIRECT I/O - The emulation of an adapter for I/O to link a host data processing system to a local area network provides advantages of memory to memory transfer which results in higher data transfer rates while at the same time providing a mechanism for working with two data transfer vectors in an overlapping fashion. | 10-02-2008 |
20080250139 | FACILITATING MONITORING AND SIMULTANEOUSLY ANALYZING OF NETWORK EVENTS OF MULTIPLE HOSTS VIA A SINGLE NETWORK INTERFACE - The substantially simultaneous tracing/monitoring of a plurality of sets of events via a single network interface. The plurality of events can be traced and/or monitored for one host or for a plurality of hosts coupled via the same network interface. The sets of events to be traced/monitored for a host are defined by the host and maintained in one or more configuration files. The configuration files may be dynamically updated. | 10-09-2008 |
20080262638 | Apparatus and Method to Integrate Hardware Adapter Diagnostics with a Host OS Diagnostics Through Signaling - The present invention provides a system and method for controlling diagnostic functions on a remote device. The system includes a host, and a network adapter in communication with the host. The system performs a method comprising receiving a diagnostic signal from the host device on the remote device, associating the diagnostic signal with a diagnostic state of the remote device, and performing a diagnostic function indicated by the diagnostic signal. | 10-23-2008 |
20080263408 | APPARATUS AND METHOD TO INTEGRATE HARDWARE ADAPTER TRACING WITH A HOST OS TRACING THROUGH SIGNALING - The present invention provides a system and method for controlling tracing functions on a remote device. The system includes means for receiving a diagnostic signal from a host device on the remote device and means for associating the diagnostic signal with a tracing state of the remote device. In addition, the system includes means for performing a tracing function indicated by the diagnostic signal. The present invention can also be viewed as a method for controlling tracing functions on a remote device. The method operates by receiving a diagnostic signal from a host device on the remote device and associating the diagnostic signal with a tracing state of the remote device. Then, the method performs a tracing function indicated by the diagnostic signal | 10-23-2008 |
20090063707 | Shared Resource Support for Internet Protocols - Creating a unique identification for each stack in partitions of a host data computer such that a plurality of partitions may share a single adapter card during an Input/Output operation wherein the adapter card is exchanging data between the host and a Local Area Network. The adapter card includes a unique identifier pool for maintaining values of unique identifiers which are available for identifying the stacks. A deleted unique identifier for a stack may be reused by newly created stacks and may be reassigned to a recreated stack, if still available, when the stack had previously been deleted by the operating system, but is then recreated. | 03-05-2009 |
20090238197 | Ethernet Virtualization Using Assisted Frame Correction - A method for Ethernet virtualization using assisted frame correction. The method comprises receiving at a host adapter data packets from a network, storing the received data packets in host memory, storing the received data packets in a hardware queue located on the host adapter, setting a status indicator reflecting the status of the data packets based on results of the checking, and sending the status indicator to the host memory. | 09-24-2009 |
20100088708 | DATA ISOLATION IN SHARED RESOURCE ENVIRONMENTS - A data connection of a shared resource is placed in isolation mode to remove its ability to communicate with other data connections of the shared resource. This ability to isolate the data connection is dynamic in that it can be turned on/off at any time. This provides increased data security for the entities using the data connection. | 04-08-2010 |
20100185898 | INPUT/OUTPUT PROCESSOR (IOP) BASED ZSERIES EMULATION - The emulation of a data processing I/O protocol employs a process which obviates the need to consider hardware specific functionality for which emulation is not an optimal solution. The particular protocol described in exemplary fashion herein is the OSA protocol as defined by Open System Adapter standards. The use of this emulation is also seen to leave in place all of the software tools otherwise employed. | 07-22-2010 |
20110153771 | DIRECT MEMORY ACCESS WITH MINIMAL HOST INTERRUPTION - Data received over a shared network interface is directly placed by the shared network interface in a designated memory area of a host. In providing this direct memory access, the incoming data packets are split, such that the headers are separated from the data. The headers are placed in a designated area of a memory buffer of the host. Additionally, the data is stored in contiguous locations within the buffer. This receive and store is performed without interruption to the host. Then, at a defined time, the host is interrupted to indicate the receipt and direct storage of the data. | 06-23-2011 |
20120110155 | MANAGEMENT OF A DATA NETWORK OF A COMPUTING ENVIRONMENT - An integrated hybrid system is provided. The hybrid system includes compute components of different types and architectures that are integrated and managed by a single point of control to provide federation and the presentation of the compute components as a single logical computing platform. | 05-03-2012 |
20120296625 | INPUT/OUTPUT PROCESSOR (IOP) BASED ZSERIES EMULATION - The emulation of a data processing I/O protocol employs a process which obviates the need to consider hardware specific functionality for which emulation is not an optimal solution. The particular protocol described in exemplary fashion herein is the OSA protocol as defined by Open System Adapter standards. The use of this emulation is also seen to leave in place all of the software tools otherwise employed. | 11-22-2012 |
