non-aligned samples from being placed together on a system. The degree to which these solutions
are less than ideal increases as the invalid data threshold is pushed to allow higher tolerances
because there is no way to determine the true utilization for invalidated sample intervals.
To resolve this issue, use a combination of the following options:
• Adjust the Maximum Invalid Data percentage allowed by the Solver.
• Adjust the Data Range in the automated task such that all workloads have sufficient valid
data.
• Collect or import additional valid data to improve the data validity percentage.
• Adjust the workload forecast model data range selection to exclude invalid periods.
If these steps are insufficient or cannot be done, remove the workloads from the scenario that
have higher percentages of invalid data, and run the Solver on the remaining workloads to obtain
the best placement for those workloads.
HP Smart Solver informational messages
While working on a solution, the Smart Solver notes any non-critical issues that it encounters.
These issues are presented on the Solution Results screen in the "Smart Solver Solution
Information" box. For example, in the following consolidation and load balance job:
Figure H-3 Example 3. Solver information messages when workload requirements exceed available
capacity
Here the Smart Solver reported that during the consolidation phase, workloads "metallica03"
and "metallica04" were removed from consideration because their workload data exceeded the
user-specified 5% threshold on the specified metrics. Any workload removed from consideration
remained on its original system. Additionally, after the load-balance phase had completed, the
Smart Solver noted that both new template systems were over capacity with respect to network
I/O because the workloads placed there had no utilization limits specified for that metric.
