Environment
Physical Networking
The physical environment of Ceph devices adopts a scheme of "two network layers + three nodes." MON, MGR, MDS, and OSD nodes are deployed together. The public network is separated from the cluster network. The two networks use 25GE optical ports for communication.
The Ceph cluster consists of Ceph clients and Ceph servers. Figure 1 shows the physical networking. Configure the networking based on site requirements.
