How to avoid frequent paging on a Red Hat Linux System

Hi,

We have a 2TB RAM Machine running Red Hat Linux 6.3 and we are seeing lots of pagefaults. Please see below

Now I am wondering how to avoid this as we are currently using at Max 1TB of RAM on any day.

How can we avoid excessive paging, page faults etc. The machine also has 2.1TB of SSDs in there

The main process we run on the machine is MSTRSvr and that't the only major application running on this host. The machine is dedicated for MSTRSvr

Please re-run sar with the addition of -b option. The reported page faults may not be resulting in real disk i/o

Yes we did see performance issues at that time, but our CPU is never very stressed. I will try to get more information for you. Can you tell me the exact SAR command for this time period.
