Patent ID: 8665723

Claim:
An Infiniband system comprising: a plurality of nodes, each node including more than one port; an IB switch connected to the plurality of nodes; and a processor configured to multicast a first ARP request from a source node, the first ARP request including an IP address of a source port of the source node; to perform load-balancing of host traffic across a plurality of ports of a plurality of nodes by sending a reply from a destination node corresponding to the IP address included in the first ARP request, the reply being sent over the source port to the source node; and to select the source port of the source node to which to respond, based on an IP over IB GUID of the destination node, wherein to select, the processor is further configured to identify a corresponding IP address of a destination node to the IP address of the source node, determine in a first level of an ARP cache a corresponding IP over IB GUID of the destination node to the IP address of the destination node, and locate a corresponding IB address to the IP over IB GUID of the destination node in a second level of the ARP cache.
