Cluster Planning

The environment planned in this document for OmniData consists of seven servers for example, which are one management node, three compute nodes, and three storage nodes. The decoupled storage-compute network is used. In the following, we will be using Ceph as the storage node for illustration:

• The management node is server1 for managing tasks.
• The compute nodes are agent1, agent2, and agent3, for running the big data query engine service.
• The storage nodes are ceph1, ceph2, and ceph3 for running the OmniData service.

A server can function as the management node, a compute node, and a storage node at the same time. In single-node mode, the operations performed on the management node, compute nodes (host nodes), and storage nodes (offload nodes) mentioned in the following sections must be performed on the same node. Figure 1 is the networking diagram.
