Figure 97 ABC Cape Town enterprise backup environment
The two cells at the ABC Pretoria MoM environment should share a Centralized
Media Management Database. This should be configured on the MoM of cell D.
The purpose of using the CMMDB is to enable the sharing of the HP StorageWorks
DLT 4115w Library between the cells. Each of the cells in the environment should
have its own Catalog Database.
The two cells at the ABC Durban MoM environment should, likewise, share a
Centralized Media Management Database. This should be configured on the
MoM of cell F. Each of the cells in the environment should also have its own
Catalog Database.
Use an HP StorageWorks DLT 4115w Library for the ABC Pretoria environment
and for the ABC Durban environment. With a capacity of 600 GB in compressed
format, this library should suffice for the company’s projected needs in the next
five years in each of these environments.
Estimating the size of the IDB
The Internal Database Capacity Planning Tool was used to estimate the size of
the IDB in cell F in a year. This tool is located at:
• On the HP-UX and Solaris Cell Managers:
/opt/omni/doc/C/IDB_capacity_planning.xls
• On the Windows Cell Manager:
Data_Protector_home\docs\IDB_capacity_planning.xls
Input parameters shown in Figure 98 on page 322 include the number of files in
the environment (2 million), the growth factor (1.2), data protection (260 weeks),
