摘要： 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.
摘要翻译：一种用于在数据处理系统中将数据从存储器传送到网络适配器的方法，装置和计算机指令。识别从存储器传输到网络适配器的帧大小。如果帧大小可以被没有余数的高速缓存行大小整除，则将有效的数据长度设置为等于length字段。然而，如果帧大小除以高速缓存行大小导致余数，则长度字段被设置为使数据与高速缓存行大小对齐。然后使用这些字段启动数据传输。

摘要： Method, system and computer program product for protecting the integrity of data transferred between an input/output bus of a data processing system and an external network. A method for protecting the integrity of data transferred between an input/output bus and a network includes generating a Cyclic Redundancy Check (CRC) value on an interface between the input/output bus and an adapter for data being transferred from the input/output bus to the network, and checking a CRC value on the interface between the input/output bus and the adapter for data being transferred from the network to the input/output bus. By adding a CRC generator and a CRC checker on the interface between the input/output bus and the adapter, end-to-end data integrity protection is provided for data transferred between the input/output bus and the network.

摘要： A number of DMA addresses are resolved to system memory addresses at a time to decrease latency time. The number of addresses resolved at a time is preferably correlated to the number of DMA addresses that can be stored in a single cache line. Additionally, system memory is allocated in larger blocks that can store all of the information from the DMA addresses in a cache line. No change is required to the operating system, which can continue to operate on the page size it is set for. All changes are made in the hardware mapping programs and in the device driver software.
摘要翻译：一次DMA地址一次解析为系统内存地址，以减少延迟时间。一次解析的地址的数量优选地与可以存储在单个高速缓存行中的DMA地址的数量相关。另外，系统存储器被分配在较大的块中，其可以存储来自高速缓存行中的DMA地址的所有信息。操作系统不需要更改，可以根据设置的页面大小继续操作。所有更改都在硬件映射程序和设备驱动程序软件中进行。

摘要： A peripheral component Interconnect (PCI) switch that has at least one control logic device that is capable of changing, on-demand, widths of dedicated buses is provided. The buses are PCI Express buses and thus, are composed of lanes. The control logic device is a lane enable register (LER). Each location in the LER corresponds to a lane of a dedicated bus and is used to enable or disable the corresponding lane. Consequently, widths of dedicated buses are changed by using the switch of the invention to add or subtract one or more lanes from the buses.

摘要： A computer implemented method, apparatus, and computer usable program code for monitoring health of a data processing system. A determination is made whether a response is received within a first time period in response to an I/O device sending a receive descriptor to the data processing system. A determination is made whether a second time period passes before the receive descriptor becomes available for sending to the data processing system in response to an unavailability of the receive descriptor for sending by the I/O device to the data processing system. A health check is performed on the data processing system if the first time period passes without receiving a response. A health check is performed on the data processing system if the second time period passes without a receive descriptor becoming available to send the data processing system.

摘要： 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.
