High Hard Faults /Sec and free mem

$

0

My Sql Server 2012  is running on server 2008. 72 Gb  Ram

The db memory settings are 30 GB Min and 64 GB Max (max for standard version)

The SSAS is set to min 7 GB and max to 60 GB.

When i have lots of huge script to execute at night I restart SSAS to make sure SQL gets all the ram it can get (is this ok ?)

I try to understand why there is such high Hard Faults/Sec on memory even if there is free Ram. Why is it  that Sql does not use that free ram instead of paging ?.

You can see in the below image, the SQL server having the memory for himself but still high hard faults/sec.  The script executed are "updates" on huge tables.

Do i have something wrong in my setup ?
