摘要： A mechanism for allowing a single physical IB node to virtualize a plurality of host channel adapters is provided. This includes providing the appearance of both a router and multiple virtual HCA's residing behind that router, to the external REAL subnet components. Each virtual host channel adapter will have unique access control levels. One or more InfiniBand subnets are virtualized in such a way that nodes residing both within the virtual subnets and in separate physical subnets are completely unaware of the virtualization. This virtualization of InfiniBand subnets significantly increases the horizontal scaling capabilities of a single InfiniBand physical component, while at the same time provides “native” network throughput for all the virtual hosts.

摘要： A distributed computing system having (host and I/O) end nodes, switches, routers, and links interconnecting these components is provided. The end nodes use send and receive queue pairs to transmit and receive messages. The end nodes use completion queues to inform the end user when a message has been completely sent or received and whether an error occurred during the message transmission or reception process. A mechanism implements these queue pairs and completion queues in hardware. A mechanism for controlling the transfer of work requests from the consumer to the CA hardware and work completions from the CA hardware to the consumer using head and tail pointers that reference circular buffers is also provided. The QPs and CQs do not contain Work Queue Entries and Completion Queue Entries respectively, but instead contain references to these entries. This allows them to be efficient and constant in size, while the Work Queue Entries and Completion Queue Entries themselves can vary in size, for example to include a variable number of data segments. Additionally, several mechanisms are provided to improve the overall efficiency of this process under different memory configurations.
摘要翻译：提供了具有（主机和I / O）端节点，交换机，路由器和互连这些组件的链路的分布式计算系统。终端节点使用发送和接收队列对来发送和接收消息。终端节点使用完成队列通知终端用户何时完全发送或接收了消息，以及在消息发送或接收过程中是否发生错误。机制在硬件中实现这些队列对和完成队列。还提供了一种机制，用于控制从消费者到CA硬件的工作请求的传送以及使用引用循环缓冲区的头和尾指针从CA硬件到消费者的完成。 QP和CQ不分别包含工作队列条目和完成队列条目，而是包含对这些条目的引用。这允许它们在高度和大小上是恒定的，而工作队列条目和完成队列条目本身可以在大小上变化，例如包括可变数量的数据段。另外，提供了几种机制以在不同的存储器配置下提高该过程的整体效率。

摘要： An apparatus and method for managing work and completion queues using head and tail circular pointers. With the apparatus and method, queue head and tail pointers are maintained in the channel interface and the host channel adapter. The head and tail pointers in the host channel adapter include a queue pointer table index and a queue page index for identifying a position within the queue. For work queues, the tail pointer in the channel interface is used to identify a next position where a work queue entry may be written. The head pointer in the channel interface is used only to determine whether the work queue is full or not. The head pointer in the host channel adapter is used to identify a next work queue entry for processing by the host channel adapter. The tail pointer in the host channel adapter is used by the host channel adapter to determine if the queue is empty. For completion queues, the head pointer in the channel interface is used to identify a next completion queue entry to be processed. The tail pointer in the host channel adapter is used to identify a next position in the completion queue to which the host channel adapter may post a completion queue entry.

摘要： An apparatus and method for swapping out real memory by inhibiting input/output (I/O) operations to a memory region are provided. The apparatus and method provide a mechanism in which a quiesce indicator is provided in a field containing the current outstanding I/O count associated with the memory region whose real memory is to be swapped out. The current I/O field and the quiesce indicator are used as a means for communicating between a shared resource arbitrator and a guest consumer. When the quiesce indicator is set, the guest consumer is informed that it should not send any further I/O operations to that memory region. When the number of pending I/O operations against the memory region is zero, a valid bit in a protection table is set to invalid, and the real memory associated with the memory region may be swapped out. Thereafter, when the memory region is swapped back in, an address translation table is updated, the valid bit is reset, and the quiesce indicator is reset so that further I/O operations to the memory region may occur.

摘要： An aliased queue pair is provided within a logically partitioned data processing system 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 disclosed in a data processing system for migrating data pages subject to DMA access by temporarily disabling selected DMA operations within a physical I/O adapter. A determination is made as to whether to disable data access DMA capabilities of the physical I/O adapter. An operating mode of the physical I/O adapter is set to a particular mode utilizing a mode bit according to the determination of whether to disable data access DMA capabilities. Only data access DMA capabilities of the physical I/O adapter are disabled when the mode bit is set. Administrative services operations continue to be performed by the physical I/O adapter when the data access DMA capabilities of the physical I/O adapter are disabled.

摘要： A method and system are disclosed for logically partitioning resources of a single channel adapter for use in a system area network. Each resource includes a partition identifier register within which is stored a partition identifier. A first one of the resources is assigned to a first partition by storing a first partition identifier in the partition identifier register within the first one of the resources. A second one of the resources is assigned to a second partition by storing a second partition identifier in the partition identifier register within the second one of the resources. Partitioning of the resources is enforced by permitting access to the first resource by only the first partition and permitting access to the second resource by only the second partition by checking the partition identifiers of each resource.
