Why split large environments into multiple cells?

•Geographical grouping of systems.

•Logical grouping of systems, for example, departments.

•Slow network connection between some systems.

•Performance considerations.

•Separate administrative control.

For a list of considerations in planning your environment, see Chapter 2 on page 57.

Data Protector allows you to manage multiple cells from a single point.

Figure 10 Single-point management of multiple cells

MoM

Data Protector provides the Manager-of-Managers to manage large environments with multiple cells. The MoM allows you to group multiple cells into a larger unit, called a MoM environment that can be managed from a single point, as shown in Figure 10 on page 46. The MoM enables virtually unlimited growth of your backup environment. New cells can be added or existing ones split.

A MoM environment does not require a reliable network connection from Data Protector cells to the central MoM cell, because only the controls are sent over the long distance connections, however the backups are performed locally within each Data Protector cell. Nevertheless, this is based on the assumption that each cell has its own Media Management Database.
