20 VM’s of various OS’s and uses
The current cluster is using the Nehalem architecture.
I’ve got the deploy two new VMs that the current system will not allow me to
configure with the Nehalem based cluster, so I’ve got to bump up the
architecture of the cluster to accommodate them.
Before i shut down all the current VMs to upgrade the cluster, I have some
questions about the effect this is going to have on the environment.
1. Will all of the current VM’s use the legacy processor architecture or will I
have to change them ?
2. Can I elevate the cluster processor functionality higher than the underlying
hardware architecture ?
3. In regards to the new cluster processor, will all of the processor
architectures below the one I choose be an option for the existing and future
I apologize for the long post and I hope that I haven’t left out any vital
