Example one
Based on the foregoing networking schematic diagram, referring to fig. 2, a flowchart of a method for Fabric interworking across a storage area network according to an embodiment of the present application is shown, which specifically includes:
step 201: a tunnel is created for connecting edge network devices of the opposite end.
The opposite end can be one Fabric network or a plurality of Fabric networks, each Fabric network is preset with edge network equipment, and a tunnel is established between the edge network equipment of any two Fabric networks.
For example: the edge network device in the Fabric1 network is edge network device A, the edge network device in the Fabric2 network is edge network device B, and a tunnel is created between the edge network device A and the edge network device B, namely, the Fabric1 network and the Fabric2 network are logically combined into an integral Fabric network, so that the Fabric1 network and the Fabric2 network are interconnected.
Step 202: and respectively creating virtual logic interfaces which are in one-to-one correspondence with the tunnels on each edge network device.
And each edge network device creates virtual logic interfaces corresponding to the tunnels one by one according to the ports of the tunnels.
When the tunnel has a plurality of ports, the edge network device may create a plurality of virtual logical interfaces and establish a one-to-one correspondence between the virtual logical interfaces and the tunnel.
The virtual logic interface is preferably a virtual logic FC interface, abbreviated as VFC interface, and may also be other logic interfaces, which is not limited in this application.
Step 203: and configuring the loopback port IP addresses of the two edge network devices which are communicated with the tunnel into the two port IP addresses of the tunnel.
For example: the two edge network devices which are communicated with the tunnel are an edge network device A and an edge network device B, the IP address of a loopback port of the edge network device A is 1.1.1.1, and the IP address of a loopback port of the edge network device B is 2.2.2.2, so that the source address of the tunnel is 1.1.1.1, and the destination address of the tunnel is 2.2.2.2.
In this embodiment, first, a tunnel is created for connecting edge network devices of opposite terminals, so that a plurality of Fabric networks are logically combined into one Fabric network, thereby enabling interconnection across IP networks.
Secondly, a virtual logic interface is established through each edge network device, and a one-to-one correspondence relationship between the virtual logic interface and the tunnel is established, so that the edge network device is connected to the IP network only through the virtual logic interface, and the problem of point-to-point limitation of an optical fiber Channel (FCoE) based on the Ethernet is solved.
Example two
Referring to fig. 3, a flowchart of a method for Fabric interworking across a storage area network according to the second embodiment of the present application is shown, which specifically includes:
step 301: and creating a tunnel for connecting edge network equipment of the opposite terminal.
Step 302: and respectively creating virtual logic interfaces VFC which are in one-to-one correspondence with the tunnels on each edge network device.

Preferably, step 305 comprises the sub-steps of:
step 3051: and receiving an FCoE message sent by an opposite terminal, and acquiring the destination edge network equipment of the FCoE message from the FCoE message.
Step 3052: and searching a corresponding virtual logic interface according to the target edge network equipment.
Step 3053: and when the output interface of the FFCoE message on the edge network equipment is the corresponding virtual logic interface, packaging the FCoEC message.
Step 3054: and encapsulating the FCoE message, the outer Ethernet header, the outer IP header and the outer TCP header to obtain the encapsulated FCoE message, wherein the IP address of the outer IP header is the IP address of the tunnel corresponding to the virtual logic interface.
Referring to fig. 4, which shows a schematic structural diagram of FCoE packet encapsulation, an outer ethernet header, an outer IP header, an outer TCP header, and an FCoE packet are encapsulated, where the FCoE packet includes: an inner Ethernet header, an inner FCoE header and message content.
When each edge network device needs to send out the FCoE message, the FCoE message needs to be encapsulated in the TCP message, that is, an outer ethernet header, an outer IP header, and an outer TCP header are added. The source IP in the outer IP header is the source IP of the FC tunnel corresponding to the VFC interface (i.e., the IP of the loopback interface on the edge network device in the source Fabric); the destination IP is the destination IP of the FC tunnel corresponding to the VFC interface (i.e. the IP of the loopback interface on the edge network device in the destination Fabric).
The destination MAC address of the outer Ethernet header is 0-0-1 of the Ethernet switch, the source MAC address of the outer Ethernet header is FCoE MAC of the edge switch A, the destination IP is 2.2.2.2, the source IP is 1.1.1.1, the destination MAC address of the inner Ethernet header is FCoE MAC of the edge switch B, and the source MAC address of the inner Ethernet header is FCoE MAC of the edge switch A.
Because the connections among the fabrics are fixed and the number of the fabrics is not large, the fabrics are encapsulated in a TCP message, the FCoE message after encapsulation is forwarded in a common three-layer mode in a public network, the FCoE message is decapsulated by the target edge network device after reaching the target edge network device, and the FCoE message is extracted and then forwarded in the target Fabric.
Step 306: and forcibly starting a priority flow control PFC on a connection interface of each edge network device and Ethernet equipment in a public network so as to enable the FCoE message after encapsulation to be transmitted without loss.
Step 307: and sending the encapsulated FCoE message to other fabrics through a tunnel.
For example: when two or more edge network devices in the Fabric1 network are provided, the encapsulated FCoE message may be sent to the tunnel in a load balancing manner, and the encapsulated FCoE message may be sent to other Fabric networks through the tunnel.
In this embodiment, first, a tunnel is created for connecting edge network devices of opposite terminals, so that a plurality of Fabric networks are logically combined into one Fabric network, thereby enabling interconnection across IP networks.
Secondly, a virtual logic interface is established through each edge network device, and a one-to-one correspondence relationship between the virtual logic interface and the tunnel is established, so that the edge network device is connected to the IP network only through the virtual logic interface, and the problem of point-to-point limitation of an optical fiber Channel (FCoE) based on the Ethernet is solved.
In order to better understand the technical solution defined in the present application, fig. 1 is taken as an example to further illustrate an optimization method for implementing the Fabric across a storage area network according to the present application.
For example: the Fabric1 network is the source Fabric, while Fabric2 and Fabric2 are the destination fabrics, and the two networks are tunneled.
When an FCF switch a (edge network device) in a source Fabric needs to forward an FCoE message, the next hop of the FCoE message is an FCF switch B, an egress interface is VFC1, a source IP of an FC tunnel bound to the VFC1 interface is 1.1.1.1, and a destination IP is 2.2.2.2.
The FCoE packet is encapsulated by the FCF switch a according to the packet structure in fig. 4, where the destination MAC address of the outer ethernet header is 0-0-1, the source MAC of the outer ethernet header is the FCoE MAC of the FCF switch B, the destination IP is 2.2.2.2, the source IP is 1.1.1.1, the destination MAC address of the inner ethernet header is the FCoE MAC of the FCF switch B, and the source MAC of the inner ethernet header is the FCoE MAC of the FCF switch B.
And the FCoE message after encapsulation reaches an FCF switch B after three-layer forwarding on the public network, and the FCF switch B decapsulates the received encapsulated FCoE message, extracts the FCoE message and forwards the FCoE message to the next FCF switch or node in the local Fabric.
When the next hop of the FCoE packet that the FCF switch a needs to forward is the FCF switch C, the egress interface is VFC2, the bound tunnel portal source IP is 1.1.1.1, and the destination IP is 3.3.3.3. The FCF switch a encapsulates the FCoE packet according to the packet structure in fig. 4, where the destination MAC address of the outer ethernet header is 0-0-1, the source MAC of the outer ethernet header is the FCoE MAC of the edge switch a, the destination IP is 3.3.3.3, the source IP is 1.1.1.1, the destination MAC address of the inner ethernet header is the FCoE MAC of the FCF switch C, and the source MAC of the inner ethernet header is the FCoE MAC of the FCF switch a.
And the FCoE message after encapsulation reaches an FCF switch C after three-layer forwarding on the public network, and the FCF switch C decapsulates the received encapsulated FCoE message, extracts the FCoE message and forwards the FCoE message to the next FCF switch or node in the local Fabric.
