摘要： A method and apparatus are provided for dynamically determining a primary adapter in a heterogeneous N-way adapter configuration. Each of the adapters generates information about itself and exchanges the information with all other adapters. First a decision-making adapter is identified. Then the decision-making adapter compares the adapter-generated information of all the adapters and makes a decision determining the primary adapter. The decision-making adapter communicates the decision to all other adapters. The determined primary adapter assumes a role as the primary adapter and the other adapters assume a role as a secondary adapter.

摘要： A method and apparatus are provided for implementing resilient connectivity in a Serial Attached SCSI (SAS) domain. A first edge expander is connected to a first port of a plurality of SAS devices for enabling communications between each of the plurality of SAS devices through the first edge expander. A second edge expander is connected to a second port of the plurality of SAS devices for enabling communications between each of the plurality of SAS devices through the second edge expander. A subtractive routing port of each of the first edge expander and the second edge expander is connected together for enabling communications between each of the plurality of SAS devices via the first ports and the second ports of the plurality of SAS devices.

摘要： A method and apparatus are provided for implementing distributed (SCSI) devices using enhanced adapter reservations. A plurality of adapters is provided. Each adapter implements a plurality of logical devices with each logical device respectively coupled to a port of the distributed SCSI devices. The adapters manage reservations for the plurality of logical devices selectively using a no reservation state, an implicit reservation state, and an explicit reservation state. The adapters arbitrarily assign one adapter for managing each of the plurality of logical devices.

摘要： A method, apparatus, system, and signal-bearing medium that in an embodiment determine whether a current number of buffers allocated to a queue pair is less than a maximum number of buffers for the queue pair, decide whether a current number of buffers allocated to an operation type is less than a maximum number of buffers for the operation, and allocate a buffer to the queue pair if the queue pair requests the buffer for an operation having the operation type and the determining and the deciding are true. In this way, too much buffer space is prevented from being assigned to particular operation and to a particular queue pair.

摘要： A method, apparatus and computer program product are provided for implementing N-way fast failover in a virtualized Ethernet adapter. Requests are posted to queue pairs (QPs) to send and receive Ethernet packets. Each QP stores a designated physical Ethernet port. At the time of a failover, the stored failed designated physical Ethernet port in a QP is changed to a new functional physical Ethernet port. An increased bandwidth is available prior to failover because all ports are used, eliminating the use of any backup, idle ports of prior fast failover arrangements.
摘要翻译：提供了一种在虚拟化以太网适配器中实现N路快速故障转移的方法，设备和计算机程序产品。请求发送到队列对（QP）以发送和接收以太网数据包。每个QP存储指定的物理以太网端口。在故障转移时，QP中存储的失败的指定物理以太网端口将更改为新的功能物理以太网端口。在故障切换之前，由于使用了所有端口，因此可以使用增加的带宽，从而无需使用先前快速故障转移安排的任何备份空闲端口。

摘要： An apparatus, program product and method maintain data coherency between paired I/O adapters by commingling primary and backup data within the respective write caches of the I/O adapters. Such commingling allows the data to be dynamically allocated in a common pool without regard to dedicated primary and backup regions. As such, primary and backup data may be maintained within the cache of a secondary adapter at a different relative location(s) than is the corresponding data stored in the cache of the primary adapter. In any case, however, the same data is updated in both respective write caches such that data coherence is maintained.
摘要翻译：装置，程序产品和方法通过在I / O适配器的相应写入缓存内混合主要和备份数据来保持配对的I / O适配器之间的数据一致性。这种混合允许在公共池中动态地分配数据，而不考虑专用的主要和备份区域。因此，主数据和备份数据可以在与适配器的高速缓存中存储的相应数据不同的相对位置上保持在辅助适配器的高速缓存内。然而，在任何情况下，相同的数据在两个相应的写高速缓存中被更新，从而保持数据一致性。
