Cisco Cisco Security Manager 4.6 Guía De Instalación

It is recommended to do disk fragmentation for every 50 GB increase in the disk size for optimal 
performance. 

Frequent defragmentation will also contribute to bad sectors, eventually leading to disk failure. 

Virtual memory (the paging file) should be 1.5 x installed memory. This is a recommendation from 
Microsoft for Windows platforms. It is not a Cisco requirement. Memory paging is necessitated only if 
the installed RAM on the system is insufficient to handle the load. 

You must deselect (clear) the checkbox “Automatically manage paging file size for all drives” 
in Windows Server 2008. The navigation path to this checkbox is Computer > Properties > 
Advanced System Settings > Performance > Settings > Advanced > Virtual Memory > 
Change. 

For Medium or Large Deployment, following parameters should be tuned to provide optimal 
performance and scalability.

Shutdown CSM using “net stop crmdmgtd” and wait until Security Manager is fully shut down
