NOTE:

The solution constraint is to change the maximum invalid data percentage allowed.

5.

Click OK.

Step 2 of 3 displays.

Step 2 of 3: Set level of effort for Smart Solver calculation

1.

Select a level of effort.

Higher levels of effort require more time and often produce better results.

NOTE:

A message appearing near the control buttons at the bottom of the screen informs

you of the amount of memory needed to generate the solution and the amount of memory
available. If the memory available is insufficient to generate the solution, you will need to
correct this situation before continuing to run the Smart Solver.

2.

Check the Smart Solver Configuration Values and Scenario Contents Summary
Information

to confirm that they match your expectations.

To change values, click Previous to return to the screen where the simulation values are set
(

step 1 of 3

).

3.

Once you are satisfied with the simulation values, click OK to begin the calculations.

The Smart Solver runs for a time, and then the results display.

Step 3 of 3: View Smart Solver solutions

1.

Review the proposed solution(s).

2.

Given these results, you can

Press Cancel to prevent these changes from being saved.

Press Save to write these changes to the scenario with which you started the load
balancing.

Press Save As... to save these changes under a new scenario name.

Press Return to Step 1 to edit the constraints prior to running the Smart Solver again.

Results: Automated load balancing of servers or VM hosts

Expected results

The solutions show workloads that are balanced across the selected existing servers or VM hosts.
Load balancing is based upon CPU, memory, network I/O, and disk I/O capacity, utilization
limits, and headroom, where the goal is to distribute workloads so that each system has
comparable headroom and therefore, similar headroom rating.

Resource capacity.

Workloads that specify utilization limits for a metric (for example, memory

or disk I/O) can only be placed on resources that define a capacity for the corresponding metric.
In other words, if you specified that a workload never exceed 100% memory utilization, that
workload can only be placed on a system for which total memory capacity is known.

Utilization limits.

Every workload selected must have at least one utilization limit applied before

using the Smart Solver. This can be any type of utilization limit, including the default global
utilization limit.

Headroom rating

The headroom rating shows the amount of available resource above the

existing resource utilization that will exist for the resulting solution in the simulation. Among
the solutions that require the same target systems, the solution with the tightest fit is shown.
