As your network grows, you will approach the maximum device/interface/flow rating for your OVA. You will want to check on this from time to time (for details, see and Checking on Device and Interface Usage and Checking on System Disk Usage).
If you find Prime Infrastructure is managing 80 per cent or more of your system resources or of the counts recommended for the size of OVA you have installed, Cisco recommends that you address this using one or more of the following approaches, as appropriate for your needs:
•
Add disk —VMWare OVA technology enables you to add disk space to an existing server easily. You will need to shut down the Prime Infrastructure server and then follow the instructions VMWare provides on expanding physical disk space. Once you restart the virtual appliance, Prime Infrastructure will make use of the additional disk space automatically.
•Limit collection—Not all data Prime Infrastructure is capable of collecting will be of interest to you. For example: If you are not using the product to report on wireless radio performance statistics, you need not collect or retain that data, and can disable the Radio Performance collection task. Alternatively, you may decide that you need only the aggregated Radio Performance data, and can disable retention of raw performance data. For details on how to do this, see Controlling Background Data Collection Tasks.
•Shorten retention—Prime Infrastructure defaults set generous retention periods for all of the data it persists and for the reports it generates. You may find that some of these periods exceed your needs, and that you can reduce them without negative effects. For details on this approach, see Controlling Report Storage and Cleanup and Controlling Data Retention.
•Off load backups and reports —You can save space on the Prime Infrastructure server by saving reports and backups to a remote server. For details, see Setting Up Remote Repositories.
•Migrate to a new server —Set up a new server that meets at least the minimum RAM, disk space and processor requirements of the next higher level of OVA. Backup your existing system, then restore it to a VM on the higher-rated server. For details, see Restoring From Backups.
