| 20080209087 | Method and Apparatus for Transferring Data from a Memory Subsystem to a Network Adapter by Extending Data Lengths to Improve the Memory Subsystem and PCI Bus Efficiency - A method, apparatus, and computer instructions for transferring data from a memory to a network adapter in a data processing system. The frame size for a transfer of the data from the memory to the network adapter is identified. If the frame size is divisible by a cache line size without a remainder, a valid data length is set equal to the length field. However, if the frame size divided by the cache line size results in a remainder, the length field is set to align the data with the cache line size. The data transfer is then initiated using these fields. | 08-28-2008 |
| 20080225733 | Methods and Arrangements to Detect A Failure In A Communication Network - Methods and arrangements to monitor communication components such as a network adapters for activity, and identify components that have lower than normal levels of activity are provided. An identified communication component can become suspect component and a candidate for further testing, including different forms of interrogation. Process for interrogating candidates can include generating and sending test packets having the media access control (MAC) address of the candidate to the candidate and if activity is not detected subsequent to the interrogation, the candidate can be flagged as a failed component. Correspondingly, the component can be deactivated and removed from service. In a further embodiment, a backup component can be activated and assume the role previously held by the failed component. | 09-18-2008 |
| 20080232349 | Optimization of Network Adapter Utilization in EtherChannel Environment - Method, system and computer program product for transferring data in a data processing system network. A method for transferring data in a data processing system network according to the invention includes determining an adapter among a plurality of adapters that has the lowest transmit latency, and assigning data to be transferred to the adapter determined to have the lowest transmit latency. The data to be transferred is then transferred by the assigned adapter. The present invention utilizes network adapters to transfer data in a more efficient manner. | 09-25-2008 |
| 20080259917 | System and Method for Improved Ethernet Load Balancing - A method for Ethernet packet load balancing includes receiving a transmit package for transmission on an Ethernet network. An offload adapter identifies a least busy port from a plurality of ports indicated in a port list, based on a byte count associated with each of the plurality of ports. The offload adapter determines whether the identified least busy port is in a working status. In the event the identified least busy port is in a working status, the offload adapter assigns the transmit packet to the identified least busy port and increments the byte count associated with the identified least busy port. In the event the identified least busy port is not in a working status, the offload adapter updates the port list and, based on a determination that there are additional working ports, assigns the transmit packet to one of the additional working ports. | 10-23-2008 |
| 20090031059 | Method, System, and Computer Program Product for Dynamically Selecting Software Buffers for Aggregation According to Current System Characteristics - A method, system, and computer program product in a data processing system are disclosed for dynamically selecting software butters for aggregation in order to optimize system performance. Data to be transferred to a device is received. The data is stored in a chain of software buffers. Current characteristics of the system are determined. Software buffers to be combined are then dynamically selected. This selection is made according to the characteristics of the system in order to maximize performance of the system. | 01-29-2009 |
| 20090141627 | Method and Apparatus for Managing Flow Control in a Data Processing System - A method in a data processing system for managing transmission of pause frames. In response to detecting an overflow condition during a receipt of data from a network, enabling flow control in response to detecting the overflow condition. The flow control is enabled as long as the overflow condition is present. A determination is made as to whether the operating system unavailable after a period of time passes. If the operating system believed to have crashed and flow control is enabled, the flow control is disabled. | 06-04-2009 |
| 20090210751 | METHOD, SYSTEM AND PROGRAM PRODUCT FOR NON-DISRUPTIVE I/O ADAPTER DIAGNOSTIC TESTING - A primary I/O adapter and a redundant I/O adapter of a data processing system are assigned to support access to a system resource. While the primary I/O adapter is in service and the redundant I/O adapter is not in service in providing access to the system resource, a fail over command is issued to remove the primary I/O adapter from service and place the redundant I/O adapter in service in supporting access to the system resource. While the redundant I/O adapter is in service and the primary I/O adapter is not in service in providing access to the system resource, diagnostic testing on the primary I/O adapter is performed. In response to the diagnostic testing revealing no fault in the primary I/O adapter, a fail back command is issued to restore the primary I/O adapter to service and to remove the redundant I/O adapter from service. | 08-20-2009 |
| 20090300211 | REDUCING IDLE TIME DUE TO ACKNOWLEDGEMENT PACKET DELAY - Mechanisms for reducing the idle time of a computing device due to delays in transmitting/receiving acknowledgement packets are provided. A first data amount corresponding to a window size for a communication connection is determined. A second data amount, in excess of the first data amount, which may be transmitted with the first data amount, is calculated. The first and second data amounts are then transmitted from the sender to the receiver. The first data amount is provided to the receiver in a receive buffer of the receiver. The second data amount is maintained in a switch port buffer of a switch port without being provided to the receive buffer. The second data amount is transmitted from the switch port buffer to the receive buffer in response to the switch port detecting an acknowledgement packet from the receiver. | 12-03-2009 |
| 20100260186 | LARGE SEND SUPPORT IN LAYER 2 SWITCH TO ENHANCE EFFECTIVENESS OF LARGE RECEIVE ON NIC AND OVERALL NETWORK THROUGHPUT - The present disclosure is directed to a method for delivering a plurality of packets from a network switch to a receiving node. The method may comprise collecting a plurality of packets received at the network switch during a time window; arranging the plurality of packets based on a source address, a package number, and a destination address for each one of the plurality of packets collected during the time window; and delivering the arranged plurality of packets to the receiving node. | 10-14-2010 |
| 20110167293 | NON-DISRUPTIVE I/O ADAPTER DIAGNOSTIC TESTING - A primary I/O adapter and a redundant I/O adapter of a data processing system are assigned to support access to a system resource. While the primary I/O adapter is in service and the redundant I/O adapter is not in service in providing access to the system resource, a fail over command is issued to remove the primary I/O adapter from service and place the redundant I/O adapter in service in supporting access to the system resource. While the redundant I/O adapter is in service and the primary I/O adapter is not in service in providing access to the system resource, diagnostic testing on the primary I/O adapter is performed. In response to the diagnostic testing revealing no fault in the primary I/O adapter, a fail back command is issued to restore the primary I/O adapter to service and to remove the redundant I/O adapter from service. | 07-07-2011 |
