Method of selectively and seamlessly segregating san traffic in I/O consolidated networks

摘要

Methods and apparatus for segregating traffic are disclosed. In accordance with one embodiment, a traffic splitter identifies a set of links coupled to the traffic splitter, where the set of links includes two or more uplinks, wherein each of the two or more uplinks are implemented in a common physical media. The two or more uplinks include a LAN uplink coupled to a LAN and a SAN uplink coupled to a SAN. The traffic splitter prevents SAN traffic from reaching the LAN via the LAN uplink. In addition, the traffic splitter prevents LAN traffic from reaching the SAN via the SAN uplink.

1. A method, comprising:
identifying by a traffic splitter a set of links coupled to the traffic splitter, the set of links including two or more uplinks, the two or more uplinks including a LAN uplink coupled to a LAN and a SAN uplink coupled to a SAN, wherein each of the two or more uplinks is implemented in a common physical medium; preventing SAN traffic from reaching the LAN via the LAN uplink; and preventing LAN traffic from reaching the SAN via the SAN uplink; wherein the steps of preventing SAN traffic from reaching the LAN via the LAN uplink and preventing LAN traffic from reaching the SAN via the SAN uplink are performed by the traffic splitter and include:
receiving a packet from a host, wherein the packet includes a VLAN identifier; andmodifying the VLAN identifier such that the VLAN identifier identifies a VLAN that carries SAN traffic or LAN traffic, wherein modifying the VLAN identifier includes modifying the VLAN identifier such that the VLAN identifier is a first VLAN identifier corresponding to SAN traffic or a second VLAN identifier corresponding to LAN traffic.
