  • Method of selectively and seamlessly segregating SAN traffic in I/O consolidated networks
    Patent number: 9509630
    Abstract: 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.

  • Unsolicited FIP packet injection by proxy and spoofing and autoconfiguring intermediate bridges using FIP snooping
    Patent number: 8767751
    Abstract: Methods and apparatus are provided for injecting Fiber Channel over Ethernet (FCoE) discovery packets, such as FCoE Initialization Protocol (FIP) or Data Center Bridge Exchange (DCBX) Protocol packets, by proxy or by spoofing into data center networks supporting FCoE in certain switchover, In-Service Software Upgrade (ISSU), and error scenarios. The transmission by proxy or by spoofing may occur at an intermediate FIP snooping bridge for communicating between FCoE devices. In this manner, the robustness of an FCoE path from one end of the data center network to another may be increased.
