Failover cluster - Memory allocation

Hi all,

Just to give you a background on what we 're trying to accomplish here:

Two host server setup with failover cluster. Both host will have VM running on it. Both host has 16Gb or RAM and the total allocated RAM for the VM on each host is 8GB. In case one of the host dies, failover will switch to the other host. But with just 6 GB free (leaving 2GB for the host), can the host still handle the load? Will it use paging files or will it just die.

Your opinion is highly appreciated.

I run 5 vm's on a Virtual Server host running 4 gig ram itself with around 1.5 gig free for host so I would think myself that 8 gig not used by vm's is more than enough.

Are you using Microsoft Virtual Server or VMWare ?   I would think with either 2 gig would be plenty, I would worry more about having the Virtual Machines on a separate drive than the host if not running a raid 5 + system.
