Data Protector Manager-of-Managers concept
Using multiple Cell Managers
Data Protector Cell Managers are split into multiple cells for various reasons:
Geographical grouping of systems
Logical grouping of systems, for example, by department
Slow network connection between some systems
Performance considerations
Separate administrative control
Data Protector provides the Manager-of-Managers (MoM) feature to centrally manage large
environments with multiple cells. MoM allows you to group multiple cells into a larger unit, called
a MoM environment that can be managed from a single point. 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 backups are performed locally within each Data Protector cell, assuming that each cell
has its own Media Management Database.
Manager-of-Manager features
Manager-of-Managers provides the following features:
Centralized licensing repository
This enables simplified license management. It is optional but useful for very large environments.
Centralized Media Management Database (CMMDB)
The CMMDB allows you to share devices and media across several cells in a MoM
environment. This makes devices of one cell (using the CMMDB) accessible to other cells that
use the CMMDB. The CMMDB, if used, must reside in the MoM cell. In this case, a reliable
network connection is required between the MoM cell and the other Data Protector cells. Note
that it is optional to centralize the Media Management Database.
Sharing libraries
With the CMMDB, you can share high-end devices between cells in the multi-cell environment.
One cell can control the robotics, serving several devices that are connected to systems in
different cells. Even the Disk Agent to Media Agent data path can go across cell boundaries.
Enterprise reporting
The MoM can generate reports on a single-cell basis as well as for the entire enterprise
environment.
