HP Service Health Optimizer enables you to perform optimization analysis to determine the optimal VM placement plan for your infrastructure. You can create multiple optimization scenarios taking into consideration the different constraints and requirements of your IT environment. Once SHO has completed optimization analysis for each scenario, you can select the best plan conducive to your IT environment.
During the optimization analysis, VMs with similar virtualization technologies are optimized together. For example, VMs running on VMware technology will be optimized together and VMs running on HyperV technology will be optimized together.
Performing optimization analysis on your IT resources helps you to:
Consolidate VMs and vDisks.
SHO provides optimal solutions to consolidate VMs and vDisks based on the conditions defined in the optimization scenario. You can select the appropriate VM and vDisk placement options available in the optimization scenario. Additionally, you can define constraints in the Edit Constraints section to customize the VM and vDisk placement.
For example, if you want to keep the existing VMs in a Group on their current hosts, then select Fixed Workload Placement from the Optimization Scenario page.
For information on how VM and vDisk placement is done, see Optimal VM and vDisk Placement.
Calculate optimal sizing for VMs.
You can calculate the optimal sizing for VMs using the VM sizing options available in the optimization scenario.
For example, if you want SHO to recommend VM size based on headroom, select the Based on Headroom option and define the CPU and memory headroom.
Perform hardware refresh.
You can replace existing VM hosts with new VM hosts using the Edit VM Hosts option of the optimization functionality.
For example, if you want to replace all the existing VM hosts with new ones, delete all the VM hosts from the Edit VM Hosts tab and add new VM hosts using the Custom Configuration option.
Physical to Virtual (P2V) analysis.
SHO helps you analyze the effectiveness of converting your physical systems to virtual ones.
For example, from the Workloads Considered for Placement drop-down list select Physical workloads. SHO considers only Physical hosts for optimization, and converts them to VMs during optimization analysis.
You can perform the above tasks by defining an optimization scenario on the Optimization Scenario page.For more information, see Creating an Optimization Scenario.
After you have created an optimization scenario, you can see the results on the Result Summary page. For more information, see Viewing Results.
