摘要： A data processing system and method of isolating a plurality of I/O adapters in the system. The data processing system also comprises a set of processors communicating with the I/O adapters using a PCIe protocol. Each of the I/O adapters has a respective ID. In the preferred embodiment the commands issued by the I/O adapters include a PCIe defined Requestor ID field including one or more of the Requestor IDs of I/O Adapters. The Req IDs can be used as an input to a CAM which provides an index to a TVT to identify a unique and independent system memory space for the I/O adapter.

摘要： A time division multiplexing (TDM) facility is presented for time division multiplexing at least two inter-system channel (ISC) data streams to create a TDM multiplexed data stream. The TDM multiplexed data stream can be forwarded across the network over a single wavelength of a wavelength division multiplexing (WDM) network. The TDM multiplex data stream may be wavelength division multiplexed with one or more other TDM multiplexed data stream. Different protocols are presented for maintaining disparity balance within the ISC data streams depending upon whether a given sequence in one of the data streams is an idle sequence, frame sequence or continuous sequence.

摘要： A method, system, and computer program product for two-sided, dynamic cache injection control are provided. An I/O adapter generates an I/O transaction in response to receiving a request for the transaction. The transaction includes an ID field and a requested address. The adapter looks up the address in a cache translation table stored thereon, which includes mappings between addresses and corresponding address space identifiers (ASIDs). The adapter enters an ASID in the ID field when the requested address is present in the cache translation table. IDs corresponding to device identifiers, address ranges and pattern strings may also be entered. The adapter sends the transaction to one of an I/O hub and system chipset, which in turn, looks up the ASID in a table stored thereon and injects the requested address and corresponding data in a processor complex when the ASID is present in the table, indicating that the address space corresponding to the ASID is actively running on a processor in the complex. The ASIDs are dynamically determined and set in the adapter during execution of an application in the processor complex.

摘要： Dropped packets are recovered in a link layer of a Data Center Ethernet (DCE) network. Data packets for transmission are stored in a replay buffer. Each data packet includes a header having a field including data indicating that the data packet is formatted for reliable recovery at the link layer. The data packets are transmitted to a receiver across a link layer in the DCE network. The receiver determines whether a data packet has been dropped. If a data packet has not been dropped, an acknowledgement signal is sent to the transmitter in another data packet across the link layer, indicating that the data packet has been received. If a data packet has been dropped, a non-acknowledgement signal is sent to the transmitter in the other data packet across the link layer, indicating that the data packet has been dropped. In response to receipt of the non-acknowledgement signal or no receipt of an acknowledgement signal after the timeout period, the dropped data packet is retrieved from the replay buffer and is resent to the receiver across the link layer.

摘要： A method and system for I/O adapters that must rely on a central processor to handle all inbound link events to reduce the number of events signaled to the central processor with hardware state machines that sort out the significant link events and automatically generate the appropriate response on the outbound link thereby greatly reducing the central processor utilization. As optical links fail (unplugging the link is a failure) or when receiving multiple continuous sequences, numerous events must be filtered by the hardware state machines to limit the number of interrupts presented to the central processor.

摘要： Controlling the flow of information between senders and receivers across links being used as channels. In one example, a self-timed interface link is adapted to be used as a channel. Such an interface is referred to as an integrated cluster bus. The flow control for the integrated cluster bus includes, for instance, a Data Request packet that indicates to the transmitter of data that it can now send the data; a continue indicator that specifies that more data is to follow; and a sequence indicator that is used to determine if a particular message is in proper sequence order. The integrated cluster bus does not require large data buffers and offers low latency messaging.

摘要： A system and method for asynchronously transmitting data blocks, in parallel, across multiple fibers in a serial manner. Frame groups are provided as a mechanism to transmit associated data serially on each fiber and tie the data being transmitted together. The frame groups can be prematurely ended on any 256 byte block boundary for several purposes, and all the frames of a given group must contain the same number of information field data words. Allowing frame groups to be ended on arbitrary block boundaries allows their transmission to start before all of the information field for the frame group has been received from a shared main processor storage. This capability of ending frame groups also allows high priority frame groups to interrupt the transmission of a relatively long data frame. Finally, the capability to end the frame group protects the information field of a stalled frame group since the CRC is sent and the idle sequence is resumed. Using multiple, independently clocked transmitters improves the fault tolerance of the link but also makes it difficult to end all frame of the frame group on the same block boundary. This problem is also solved by keeping track of the data sent to the multiple transmit buffers.
摘要翻译： 一种以串行方式跨多个光纤并行传输数据块的系统和方法。 帧组被提供为用于在每个光纤上串行发送相关数据并将正在发送的数据结合在一起的机制。 为了多个目的，帧组可以在任何256字节块边界上过早地结束，并且给定组的所有帧必须包含相同数量的信息字段数据字。 允许帧组在任意块边界上结束允许它们在从共享主处理器存储器接收到所有帧组的所有信息字段之前开始传输。 结束帧组的这种能力还允许高优先级帧组中断相对长的数据帧的传输。 最后，结束帧组的能力保护失速帧组的信息字段，因为CRC被发送并且空闲序列被恢复。 使用多个独立时钟的发射机提高了链路的容错能力，也使得难以在同一块边界上结束帧组的所有帧。 通过跟踪发送到多个发送缓冲区的数据来解决这个问题。
