The two cells at the ABC Durban MoM environment should also share a Centralized
Media Management Database. This should be configured on the MoM of cell F to
enable the sharing of the HP StorageWorks DLT 4115w Library between the cells.
The following is a detailed account of the proposed solution:
Proposed solution in detail
• Cell Configuration
Configure the departments into 7 cells, of which three are at ABC Cape Town,
and two each at ABC Pretoria and ABC Durban.
Why configure into seven cells?
• Because ABC’s departments are geographically dispersed, it would be difficult
to manage them from a single cell. Moreover, there may be networking
problems between the systems. The configuration also coincides with number
of departments, which is an important aspect in terms of security. Each of the
cells is also of the recommended size of 30 to 50 client systems. Note, however
that this number depends among other things on the number of files and
directories in individual client systems.
Then configure each of the three locations as a Manager-of-Managers environment.
The MoM allows you to efficiently, transparently and centrally manage your cells
from a single point. This then enables you to configure the Centralized Media
Management Database (CMMDB) in each MoM environment.
Why use the CMMDB?
• The Centralized Media Management Database (CMMDB) enables all cells in
a MoM environment to share devices and media. Each of the three MoM
environments at ABC can then use a single library, shared by client systems
in all cells in the environment. Using only one very large library for all ABC’s
data would not make much sense, because it would require that huge amounts
of data be transferred over WAN for backup purposes.
Use a Catalog Database in each of the 7 cells. The systems in the cells would be
as depicted in Table 24 on page 319:
