Begin with a scenario, Choose the vm hosts or servers to load-balance, Step 1 of 3: define the solution constraints – HP Matrix Operating Environment Software User Manual

NOTE:
The solution will adhere to the existing utilization limits. For information on utilization
limits, see
“Utilization limits ” (page 27)
Begin with a scenario
From the list of Capacity Advisor scenarios , select an existing scenario to edit by either:
•
clicking the linked name of an existing scenario that includes the workloads and servers
you wish to modify, or
•
checking the box next to an existing scenario that includes the workloads and servers you
wish to modify. Then, from the menu select Modify
→Edit Planning Scenario .
A new window opens to display the Edit Scenario: System tab screen.
(If you have not yet created a suitable scenario, you will need to do so (see
).)
Choose the VM hosts or servers to load-balance
Take the following actions on the Edit Scenario System Tab.
1.
Using the check boxes, select the VM hosts or servers that you plan to load-balance.
NOTE:
Though the HP Smart Solver is now aware of what-if VMware DRS clusters,
solutions can be presented that do not account for other cluster relationships (such as a
Serviceguard cluster). To preserve these cluster relationships in a simulation, create a scenario
that includes all members (hosts and guests) from the cluster that you want to represent in
the scenario.
TIP:
Before running the HP Smart Solver automation, ensure that your source systems do
not violate any of the utilization limits set for those systems. (See (and mouse over) the
utilization meters on the System tab of the scenario editor to check this information.) When
systems violate utilization limits, the Smart Solver solutions are unlikely to be useful.
“Understanding the consolidation task” (page 36)
illustrates this situation.
2.
Select What-If Action
→Automated Load Balance of VM Hosts....
The window displays step 1 of 3 for Automated Load Balance of VM Hosts....
If you want to load-balance servers, select What-If Action
→Automated Load Balance of
Servers...
Step 1 of 3: Define the solution constraints
1.
Change the Meter Style, if desired.
2.
Change the Data Range if a different interval is desired, and click OK to refresh the table
display.
TIP:
Longer intervals provide a better picture of activity on the system over time than
shorter intervals do.
3.
Change the Meter Representation if a different calculation is desired .
4.
Change solution constraints, if desired.
