System and method for improved communication in a storage network

摘要

A system and method of improved communication in a storage network includes a storage node. The storage node includes a control unit and a plurality of local ports coupled to the control unit and configured to couple the storage node to a storage network. The control unit is configured to discover port addresses of other storage nodes in the storage network, select a first port pair including a first source port selected from the local ports and a first destination port selected from remote ports associated with the port addresses of a first one of the other storage nodes, open a first connection between the first source port and the first destination port, determine whether a less desirable notice associated with the first port pair is received, and when the less desirable notice is received, record the first port pair as being less desirable.

1. A method of communicating in a network, the method comprising:
selecting, by a first network node, a first port from a plurality of second ports of the first network node; selecting, by the first network node, a third port from a plurality of fourth ports of a second network node, the first port and the third port forming a first port pair; opening a first connection between the first port and the third port for a data exchange between the first network node and the second network node; determining, by the first network node, whether a less desirable notice associated with the first port pair is received at the first port from a switch along a path of the first connection based on whether the less desirable notice includes an address of the first network node and an address of the second network node; and when the less desirable notice is received, recording, by the first network node, the first port pair as being less desirable to indicate that it would be advantageous to use a different port pair to exchange network packets between the first network node and the second network node.
