You manage your virtual environment by using Microsoft System Center Virtual Machine
Manager (VMM) 2008 R2. You monitor the environment by using Microsoft System Center
Operations Manager 2007 R2. You need to enable automatic migration between Hyper-V
host servers. Which two actions should you perform? (Each correct answer presents part of
the solution. Choose two.)
A.
Create a host group and add the host servers to it.
B.
Configure reserve resources on each host server.
C.
Use Intelligent Placement to place VMs on the host servers that have the highest rating.
D.
Configure Performance and Resource Optimization (PRO) Tips.
Explanation:
So what is PRO?
PRO is workload- and application-aware resource optimization. With PRO, we can create
policies that act upon tips, provided by SCOM as part of its OS and application monitoring
ability, to address potential resource utilization problems. In some ways, PRO is kind of like
VMware DRS, but since Hyper-V doesn’t provide any live migration functionality. In that
regard, it falls far short of matching the DRS functionality. However, where it exceeds
VMware DRS is in more detailed knowledge about the applications and services running
inside the VM, instead of acting only upon the “external view” of the VM’s resource
requirements. This is why I think that the VMware acquisition of B-Hive is critical, because it
begins to give VMware the same kind of “application awareness” inside the VM so that DRScan act upon service-level agreements or service-level status. PRO also provides an
extensible framework (assuming via SCOM’s management/monitoring capabilities) to allow
hardware vendors to supply hardware monitoring information and other software vendors to
provide more detailed information and extensions to PRO. Examples include Brocade
(presumably to provide Fibre Channel fabric information), Emulex (Fibre Channel HBA
information), EMC (storage array performance information), and HP (server hardware
information). Example, a couple of VMs generating high CPU load on the host. By telling
PRO to fix the problem, SCVMM’s intelligent placement is invoked and a new host is
selected for the VM. The VM is then migrated to the new host.
