IMPLEMENTING REDUNDANCY ON INFINIBAND (IB) NETWORKS
First Claim
1. A method of implementing redundancy for Infiniband (IB) networks, the method comprising:
- detecting a failure at a first source port of a source node having a plurality of source ports;
selecting a new source port of the source node;
sending an address resolution protocol (ARP) announce message to one or more other nodes in communication with the source node, the ARP announce message including an IP address of the second source node and an IB address of the new source port of the source node; and
re-balancing host traffic.

Abstract
Methods, systems, and physical computer-readable storage medium are provided to improve efficiency of systems operating on internet protocol (IP) over Infiniband (IB) networks. In an embodiment, by way of example only, a method is provided for implementing redundancy for IB networks. The method includes detecting a failure at a first source port of a source node having a plurality of source ports, selecting a new source port, sending an address resolution protocol (ARP) message to one or more other nodes in communication with the source node including an IP address of the source node and IB address of the new source port of the source node, and re-balancing host traffic.

9. 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 detect a failure at a first port of a first node; to select a new source port of the first node; to send an address resolution protocol (ARP) announce message to one or more nodes of the plurality of IB nodes in communication with the first node, the ARP announce message including an IP address of the first node and IB address of the new port of the first node; and to re-balance host traffic across the plurality of IB nodes. - View Dependent Claims (10, 11)
