We have a 3 node Hyper-V cluster with each server having 96GB RAM and 2 73GB disks in a RAID 1 for the host machine OS (2008 R2). The last thing we want to happen is for the host to expand the pagefile.sys and consume the entire C drive. It is currently a little over 16GB. What would be the recommendation for setting the min and max pagefile.sys size?
Note: This is for the hosts, not the guests. 96GB RAM and 73GB C drive.
Don't think it matters but just in case. All three host machines have dual 1 Gbps Ethernet connections to an iSCSI SAN using the Broadcom iSCSI offload engine, multipathed. They are Dell R610 servers running 2008 R2 Datacenter with Hyper-V.
It's not as cut and dry as you might think, but the following MS Support article lays it out pretty well:

Up front, I'm more familiar with VMware than Hyper-V. That being said, best practice in a virtual environment is generally to set the pagefile at a fixed size - min and max the same - at about 150% of the RAM allocation. Then you know exactly how big it will be, and in a virtual environment (particularly with thin-provisioned disks), this keeps the pagefile from eating up space that doesn't get recovered when it doesn't need it all.
