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： In a first aspect, a first method is provided for sharing a multiple queue Ethernet adapter. The first method includes the steps of receiving a frame or packet in the adapter and determining whether the frame or packet is for one or more of a plurality of partitions that share the adapter. If the frame or packet is for one or more of the plurality of partitions that share the adapter, the method further includes (1) storing the frame or packet in an adapter cache memory; (2) determining one or more of the plurality of partitions to which the frame or packet is to be sent; and (3) transferring the frame or packet from the adapter cache memory to a receive queue of each of the one or more partitions to which the frame or packet is to be sent. Numerous other aspects are provided.
摘要翻译：在第一方面，提供了一种用于共享多队列以太网适配器的第一种方法。第一种方法包括以下步骤：在适配器中接收帧或数据包，并确定帧或数据包是否是共享适配器的多个分区中的一个或多个。如果所述帧或分组是用于共享所述适配器的所述多个分区中的一个或多个分区，则所述方法还包括（1）将所述帧或分组存储在适配器高速缓冲存储器中; （2）确定要发送帧或分组的多个分区中的一个或多个; 和（3）将帧或分组从适配器高速缓存存储器传送到要发送帧或分组的一个或多个分区中的每一个的接收队列。提供了许多其他方面。

摘要： An I/O adapter sharing mechanism in a logically partitioned computer system allows sharing a network I/O adapter between logical partitions in an efficient manner. A first logical partition owns (or controls) the I/O adapter, and a second logical partition desires to use (or share) the I/O adapter. An I/O adapter device driver that includes a hardware interface is provided in the first logical partition. A virtual device driver is provided in the second logical partition that provides a set of functions that is at least partially defined by querying the I/O adapter device driver in the first logical partition. The I/O adapter sharing mechanism includes a transfer mechanism that allows data to be transferred directly from the virtual device driver in the second logical partition to the I/O adapter without passing through the I/O adapter device driver in the first logical partition.

摘要： Methods and systems for auto-configuration of an internal network interface are disclosed. Embodiments may install an internal VLAN manager in a logically partitioned computer system along with network agents in each of the partitions in the logically partitioned system to facilitate configuring an internal communications network and the corresponding internal network interfaces in each participating partition. In particular, an administrator accesses internal VLAN manager, selects an internal VLAN ID, selects each of the participating partitions, and configures the communications network with global parameters and ranges. The internal VLAN manager then generates partition parameters and incorporates them into messages for each of the partitions selected to participate in the internal network. Each of the participating partitions receives one of the messages and, in response, invokes the corresponding network agent that extracts partition parameters from the message and creates or re-configures an internal network interface based upon the parameters.
摘要翻译：公开了用于自动配置内部网络接口的方法和系统。实施例可以将逻辑分区计算机系统中的内部VLAN管理器与逻辑分区系统中的每个分区中的网络代理一起安装，以便于配置内部通信网络和每个参与分区中的对应内部网络接口。特别是，管理员访问内部VLAN管理器，选择内部VLAN ID，选择每个参与分区，并配置全局参数和范围的通信网络。内部VLAN管理器然后生成分区参数，并将其并入被选择参与内部网络的每个分区的消息中。每个参与分区接收一个消息，并作为响应，调用从消息中提取分区参数的相应网络代理，并根据参数创建或重新配置内部网络接口。
