Windows Server 2008 R2 consuming all available RAM for CACHE

I am running a windows server 2008 R2 standard as a host for 6 virtual machines. The server has 2 x quad core XEONS and 32GB of Ram.

After I restart the host, I can boot all the virtual machines boot and consume the expected amount of RAM and for a few hours cache RAM remains low when viewed from TASK Manager. If I log in 6 to 10 hours after the host is restarted and all VM's are running, the HOST has consumed all remaining RAM (as much as 12GB) into CACHE and leaving ZERO FREE memory.

At first I thought this might be a Backup Program I was running, so I uninstalled it, and other than the base services for the HOST, I have no other applications running on the HOST. I have no idea why the server is consuming ram and I'm not sure if this is or can be affecting the performance of the VM's. Any thoughts on how to manage the CACHE memory or even how to clear it would be appreciated.
