摘要： In an embodiment a translation of RID (requester identifier) ranges to identifiers of north chips is stored into a south chip. A command that comprises a command RID is received at the south chip from a device. In response, a RID range is determined that encompasses the command RID, and a north chip identifier is found that is assigned a virtual function identified by the command RID. The command is sent from the south chip to the north chip identified by the north chip identifier. The translation comprises a RID compare value and a RID mask. A determination is made that the RID range encompasses the command RID by performing a logical-and operation on the command RID and the RID mask and comparing a result of the logical-and operation to the RID compare value.

摘要： A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address.

摘要： A firmware update process for a self-virtualizing IO resource such as an SRIOV adapter is incorporated into a platform firmware update process to systematically update the resource firmware in a manner that is for the most part transparent to the logical partitions sharing the adapter. In particular, resource firmware associated with a self-virtualizing IO resource is bundled with firmware for at least one adjunct partition associated with that self-virtualizing IO resource within a common firmware image so that, upon restart of the adjunct partition to use the updated firmware image, the resource firmware is also updated, with a logical partition that uses the self-virtualizing IO resource maintained in an active state during the restart, and without requiring the self-virtualizing IO resource to be deconfigured from the logical partition.
