Abstract:
1. A system for supporting network interface card (NIC) failover in a management network of an Infiniband (IB) fabric, comprising: a remote management node having a remote machine address and comprising a microprocessor, a remote Network Interface Card (NIC), and a remote NIC driver; a local management node comprising a microprocessor, a local Network Interface Card (NIC), and a local NIC driver; wherein the remote management node is connected via the remote Network Interface Card (NIC) and the local NIC to the local management node to form an management Ethernet network; wherein the local management node is configured to detect failure of the remote Network Interface Card (NIC); wherein the local management node is configured to establish a remote proxy instance, running on the microprocessor, on the local management node, wherein the remote proxy instance associates the remote machine address with the remote NIC driver on the remote management node, and wherein the local management node is configured to, direct packets at least one of to and from the remote NIC driver over the IB fabric using the remote machine address in response to detecting failure of the remote Network Interface Card (NIC).
