ABSTRACT:
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.
