is that it can require more administrative work or might even require a separate administrator for each cell.
•Size of each cell
The size of a Data Protector cell affects backup performance and the ability to manage the cell. The recommended maximum size for a Data Protector cell is 100 client systems. Cells with more than 200 client systems are less manageable.
•Network considerations
All client systems of a cell should be on the same LAN for maximum performance. For more information about other network considerations such as your network configuration, see the sections that follow.
•Geographical location
If the client systems you want to back up are geographically dispersed, it may be difficult to manage them from a single cell and there may be networking problems between the client systems. Additionally, the security of data may be an issue.
•Time Zones
Each cell should be within one time zone.
•Security of data
Data Protector provides cell level based security. All Data Protector administrative work is done in the context of a single cell: media, backup devices, and backed up data belong to one cell. Note that Data Protector lets you share devices or move media between cells, so physical access to media must be limited to authorized personnel.
•Mixed environments
Data Protector allows you to back up client systems of diverse platforms in a single cell. However, it may be convenient to group client systems in a cell based on the platforms. For example, you may have one cell with the Windows client systems and one with the UNIX client systems. This is especially useful if you have separate administrators and policies for the UNIX and Windows environments.
•Departments and sites
You can group each department or site in a separate cell. For example, you may have one cell for the accounting, one for the IT, and one for the manufacturing department. Even if you choose to have several cells, Data Protector allows you to easily configure common policies among the cells.
