Environment
Physical Networking
The physical environment of the Ceph block devices contains two network layers and three nodes. In the physical environment, the MON, MGR, MDS, and OSD nodes are deployed together. At the network layer, 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 networking mode.
