A cell is a grouping of nodes into a single administrative domain. In the Base and
Express configurations, a cell contains one node and that node contains one
server. See Figure 3-6.

Deployment environment
In a Network Deployment environment, a cell can consist of multiple nodes (and
node groups), which are all administered from a single point, the deployment
manager (Figure 3-6). If your cell configuration contains nodes running on the
same platform, it is called a homogeneous cell. It is also possible to have a cell
made up of nodes on mixed platforms. This is referred to as a heterogeneous cell.
Figure 3-5 on page 60 shows a cell containing multiple nodes and node groups.

Note: See 3.2, “Server environments” on page 73 for detailed information
about the various cell configurations.
