Deployment Network

Figure 1 Deployment network

As shown in Figure 1, three Kunpeng servers and two x86 servers form a Kubernetes hybrid cluster, and three Kunpeng servers form a Ceph cluster to verify the storage access function of Kubernetes. The BMC management network ports of all servers are connected using a GE switch, and the service network ports are connected using a 10GE switch.
