摘要： A method, computer program product, and data processing system for providing system-area network (SAN) multicasting functionality in a logically partitioned (LPAR) data processing system in which a channel adapter is shared among a plurality of logical partitions is disclosed. A preferred embodiment of the present invention allows LPAR “hypervisor” firmware to assume the responsibility for multicast protocol handling and distribution of packets among logical partitions.

摘要： A method, system, and computer program product are disclosed within a logically partitioned data processing system for providing an aliased queue pair for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.

摘要： A method, apparatus and computer program product are provided for implementing dynamic Virtual Lane buffer reconfiguration in a channel adapter. A first register is provided for communicating an adapter buffer size and allocation capability for the channel adapter. At least one second register is provided for communicating a current port buffer size and one second register is associated with each physical port of the channel adapter. A plurality of third registers is provided for communicating a current VL buffer size, and one third register is associated with each VL of each physical port of the channel adapter. The second register is used for receiving change requests for adjusting the current port buffer size for an associated physical port. The third register is used for receiving change requests for adjusting the current VL buffer size for an associated VL.

摘要： A method for coalescing acknowledge packets within a server is disclosed. A Read Request queue having multiple queue pair entries is provided. Each of the queue pair entries includes a packet sequence number (PSN) field and an indicator field. In response to a receipt of a Write Request packet, an indicator field of a queue pair entry is set to indicate that an Ack packet has been queued within the queue pair entry, and a PSN of the Write Request packet is written into a PSN field of the queue pair entry. In addition, a Queue Write Pointer is maintained to point to the queue pair entry. In response to a receipt of a Read Request packet, the indicator field of the queue pair entry is set to indicate that a Read Request packet has been queued within the queue pair entry, and a PSN of the Read Request packet is written into the PSN field of the queue pair entry. Also, the Queue Write Pointer is advanced to point to a queue pair entry that is subsequent to the queue pair entry.
摘要翻译：公开了一种用于在服务器内聚合确认分组的方法。提供了具有多个队列对条目的读请求队列。每个队列对条目包括分组序列号（PSN）字段和指示符字段。响应于写请求分组的接收，设置队列对条目的指示符字段以指示Ack分组已经在队列对条目中排队，并且写请求分组的PSN被写入PSN字段的队列对条目。此外，维护队列写入指针以指向队列对条目。响应于读取请求分组的接收，队列对条目的指示符字段被设置为指示读取请求分组已经在队列对条目中排队，并且读取请求分组的PSN被写入PSN 字段的队列对条目。此外，队列写入指针被提前指向队列对条目后面的队列对条目。
