Certainly, if having two network interface servers without the route that is configured to IPSAN, VM can not send notice message to this pair of network interface server; Or IPSAN is without the route that is configured to certain two network interface server, VM, in sending to the notice message of IPSAN, can not carry two network interface IP address of this server.
By the above flow process of the embodiment of the present invention, on two network interface servers, all can automatically be generated to the monitoring network segment route of region A and to the monitoring network segment route of region B.
Route based on configuring by the way, the flow process of storage service can as shown in Figure 5, comprise:
Step 501, when EC need to store the video flowing after coding into IPSAN, sends service request message to VM.
Step 502, VM selects IP address that IPSAN connects this region as service IP address according to this EC region for it, and by response message, this IPSAN network interface IP address is returned to this EC.
During concrete enforcement, the network interface that EC can connect this its region of EC to VM sends service request message, so VM can determine the region at this EC place, and the network interface IP address that connects this region for this EC selection IPSAN is as service IP address.In the situation that in VM to registered EC mark the region at its place, VM also can determine according to this mark the region at the EC place of initiating business request message.
