What is "Memory Page out Rate"

Question

Could somebody please tell me what is "Memory Page Out Rate". I have seen this in "HP Open View" server monitoring tool and tried googling it. Would appreciate if some expert can clarify.

If page out rate is too high as 200+ per second, can it crash the server?

Thanks in advance

"Page Out Rate (KB per Second) The number of kilobytes that the virtual memory manager pages out per second averaged over the previous 30-second interval. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 2147483648 indicates Value_Exceeds_Minimum, and -2147483647 indicates Value_Exceeds_Maximum."

A page-out rate of 200kb/s could be fine on some systems and service affecting on others. It all depends on how fast your disks/san can keep up.

To be honest you'd be better off asking this question in one of these more suitable sites, SO is for programming related questions, not sysadmin queries:
