Hi,

We've jsut upgraded to ESXi5.0 U1 and enabled DRS. Now when i get in in the morning i find that the latest/best specced VM is is running most of the big VMs and the mem usage is <90%. The other hosts have mem usage of 20 - 30%. How can we better balance the load over all the hosts.  We'vre running 2 DL380 G5s and 1 DL 380 G7 and will soon be adding a DL380 g8

Cheers

In your Datacenter settings under vSphere DRS what is your automation level? I think the default is Fully automated. Additionally you can adjust the migration threshold from conservative to aggressive.

Check out this Yellow Bricks write up on DRS:

DRS bases it's average on CPU and Memory, when the VMs are actually using the resources.

So you will find periods, when hosts are "unbalanced". DRS is not a load balancer.

Yes, it will be better. But check the Virtual Servers you are also using, e.g. Citrix and Terminal Servers do not behave well, if being vMotion around all the time.
