| 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 |
| 20090259743 | DYNAMICALLY CALCULATING AN INBOUND BLOCKING FACTOR USING OPERATING-SYSTEM-LEVEL CONDITIONS - A current value of a changing operating-system-level condition can be determined, wherein the operating-system level condition is a condition of a host related to an operating system resource utilization or an operating system experienced latency. The operating-system level condition can be a condition of a layer of the OSI model above the Data Link Layer. An inbound blocking factor algorithm can execute that uses the determined current value as a variable. A value for an inbound blocking factor can be generated as a result of executing the inbound blocking factor algorithm. The generated value can be utilized as the inbound blocking factor to determine a manner in which incoming messages are to be conveyed from a network adaptor, through an adaptor interface boundary, to an operating system of the host. | 10-15-2009 |
| 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 |
| 20100138567 | APPARATUS, SYSTEM, AND METHOD FOR TRANSPARENT ETHERNET LINK PAIRING - 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. | 06-03-2010 |
| 20100138579 | NETWORK ADAPTOR OPTIMIZATION AND INTERRUPT REDUCTION - A method and system are disclosed for network adaptor optimization and interrupt reduction. The method may generate an immediate I/O interrupt notification to a host device driver in response to receiving data from a network. The method may also update an inbound buffer list based on the received data in the inbound buffer queue. Furthermore, the method may set the buffer state from an empty state to a primed state to indicate that the received data is available for processing. The method may also build an outbound buffer list based on outgoing data and add the outgoing data to an outbound buffer queue. Furthermore, the method may set a buffer state from an empty state to a primed state to indicate that the outgoing data is prepared for transmitting and signal a network adaptor with a notification signal. | 06-03-2010 |
| 20110126194 | SHARED SECURITY DEVICE - A mechanism is provided for sharing one or more security appliances. A trusted system component associated with an application of a plurality of applications in a logically partitioned data processing system sets a destination address of a received packet to an address of a security appliance shared by the plurality of applications. The trusted system component sends the received packet to the security appliance. The trusted system component receives a response from the security appliance. The trusted system component determines whether the response indicates permitting the received packet to proceed to the intended recipient. The trusted system component sends the received packet to the recipient in response to the response indicating permitting the received packet to proceed. | 05-26-2011 |
| 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 |
