1. A method for failover in a storage network, comprising:

  • detecting a failure of a first server;

    activating a secondary virtual port associated with a physical port of a second server, the physical port configured to support two or more virtual ports that share the physical port on the second server;

    configuring the secondary virtual port with an identity of a primary virtual port from the first server, wherein configuring the secondary virtual port with the identity of the primary virtual port comprises setting a node name of the secondary virtual port to a node name of the primary virtual port that is unique to the first server; and

    servicing one or more storage devices operatively connected to the first server and second server through the node name of the secondary virtual port.
