Overlay network capable of supporting storage area network (SAN) traffic

摘要

In one embodiment, a system includes a server having a hypervisor layer that includes an overlay-configured virtual switch and a Fiber Channel (FC) virtual switch. The system also includes at least one processor configured to execute logic and a converge network adapter (CNA) coupled to the hypervisor layer. The CNA is configured to communicate with the overlay-configured virtual switch and the FC virtual switch, and with a FC forwarder (FCF). Moreover, the overlay-configured virtual switch includes logic configured to communicate with a central controller. In another embodiment, a method includes receiving a block of media access control (MAC) addresses for use in local fabric initialization protocol (FIP) operations and advertising to all local Fiber Channel over Ethernet (FCoE) initiators to route FCoE traffic to a FC virtual switch by asserting an overlay-configured virtual switch as a FCF for any requesting FCoE initiators.

1. A system, comprising:
a server, comprising:
a hypervisor layer, comprising:
an overlay-configured virtual switch; anda Fibre Channel (FC) virtual switch;at least one processor configured to execute logic; anda converge network adapter (CNA) coupled to the hypervisor layer, the CNA being configured to communicate with the overlay-configured virtual switch and the FC virtual switch, and wherein the CNA is configured to communicate with a FC forwarder (FCF),wherein the overlay-configured virtual switch comprises:
logic configured to communicate with a central controller, the central controller being a Distributed Overlay Virtual Ethernet (DOVE) controller;logic configured to receive a block of media access control (MAC) addresses from the DOVE controller for use in local fabric initialization protocol (FIP) operations, the local FIP operations comprising assigning MAC addresses to local Fibre Channel over Ethernet (FCoE) initiators; andlogic configured to advertise to all local FCoE initiators to route FCoE traffic to the server by asserting the overlay-configured virtual switch as a Fibre Channel forwarder (FCF) for any requesting FCoE initiators.
