For my network at home I am using two Supermicro RI1102H servers. Both servers have four GigabitEthernet adapters plus one out-of-band-management adapter.
Both servers are running XCP-NG Hypervisor, the open-source version of Citrix XEN server for virtualization.
My two Cisco C3750G-24TS-S switches are stacked, so I can build up a high-availability setup for my virtual environment.
For the servers I created two bond interfaces, one for “data” and the other for “storage” traffic.
On the Cisco switches I created two Port-Channels from the GigabitEthernet interfaces. The setup of the interfaces is illustrated below:
This means the traffic is divided between the “data” and “storage” traffic. By following the manual of XCP-NG I added the two servers as nodes into a pool as shown below:
So the HA is enabled with two nodes in the pool and the status is healthy.
