Memory System Cache @ 97%

Hello:

I was wondering if its normal for the System Cache to consume 97% of the Physical Memory - for example my total system memory reads as 8114.77MB and the system cache is at 7552.65MB. The reason I ask is we have started to monitor the cpu and memory by snmp and the captured data for memory shows at 97% usage.

And the memory usage graph:

Thanks.

Man, r u using the same Open-e we are using... that screen shot look different... or maybe its old...

As far as I know.. Open-e system cach most of the memory and use it. but if other programs/softwares/ or whatever needs it, it drops the needed memory
