Hi all
We have a Windows 2008 R2 Enterprise x64 host with 48GB memory, First data partition is 375GB (RAID1 120GB free) and second is 558GB (RAID1 50GB free)
Windows is managing the paging file and has set a 50GB pagefile on each data partition.
VMware server has 40GB reserved and is set to fit all virtual machine memory into reserved host ram.
We currently have 8 VMs running without an issue, using 32GB
When we start up a 9th, it takes a long time to load up and there is a significant amount of Hard Faults/sec that eventually recede to zero (after about 15/20 minutes) but performance of the 9th and the other VMs is affected - high CPU and poor overall performance exhibited as websites are slow to respond and timeout.
During all this the host CPU is not stressed
The VM starting up runs perfectly fine on my local machine using VMware player, and is a sysprepped image of the the other VMs.
Does anyone have any observations on why the disk thrashing is occuring and what I can do to remedy it?
Thanks
