Task: Determining where to put a workload using automated solution
finding
Adding a new application or set of applications to an existing server environment requires careful
planning. Deciding where to add the new workload can be challenging; can it be placed on an
existing server, or is a new system required? With HP Insight Capacity Advisor software, the
planning can be based on real data and realistic modeling of the results of adding a new workload
to the current environment.
Prerequisites
•
You should be familiar with Capacity Advisor operations (see
).
•
You must be logged in to Insight Dynamics. (See
“Accessing Capacity Advisor” (page 55)
•
You must have already collected data on the systems of interest (see
).

Example: Determining where to put a workload
1.
Obtain data from a test machine
The most accurate models are based on real data, collected over a long enough period of
time to capture the variations in load due to periodic peaks in usage (such as events
happening “late Thursday night” or “the first and 15th of the month”). Collect data for at
least a week, and preferably for long enough to capture any periodic variations. If you cannot
collect data from a test machine and have data from a similar application running on an
existing system, you can create a new workload based on the existing data and scale it to
provide a “best guess” model of the new application's resource utilization.
2.
Create a scenario
Follow the procedure in
“Creating a planning scenario” (page 86)
to create a scenario with
the test system running the new application and all the candidate host systems.
3.
Edit the workload
Follow the procedure in
“Editing a workload” (page 101)
to make any modifications to the
data collected on the workload necessary to reflect estimated future production loads. This
might include increasing the processor load and/or memory usage.
