in Operations Manager v5.1, VMTurbo Engineering has done it again in defining a better user experience to answer important questions on how to plan for future demand! Use Continuous Projections to answer the question "How much compute and storage is needed and when, for a simulation of projecting workload demand changes over different periods of time?". This Turbo Tip reviews how to leverage a new workflow we introduced with Continuous Projections available in the Plan tab. Remember to consult your VMTurbo User Guide for more information.
New Design: Configure - Run - Results. When you first open Plan -> Projections, you will notice when you start a new plan, you will be presented with the "Configure" view that is neatly organized into 2 sections:
"Plan Setup" = takes you through a easy-to-follow workflow where you can configure your scenario, modifying the following items (many of these you can do in any plan but now we give you a better workflow):
- Time periods - how far into the future to run your projection
- Baseline - modify the baseline of your snapshot; add overall more utilization, change to a High Demand period, or go back any day in the past 60 days.
- Demand - modify how to represent your demand; include reservations, add or remove VMs (clones of real VMs or templates), etc
- Supply - modify your resources such as replace compute and storage with templates, etc
- Advanced Settings - modify other settings such as eliminating specific constraints, decide to allow resizing, and more
"Current Resources Summary" = the current resources overview of the scope you are in. This is the same details you see for your scope in the Capacity Dashboard
"Current Environmental Summary" = the inventory summary of your scope. This is the same view you can see in Admin -> Target Configuration, except here in the Plan it is scoped.
After you have you have configured your plan (Scope, then Plan Setup), when you hit Run, once the Plan is finished, the user interface will automatically change over to present you with the "Results" with predefined views that help you see the answers:
- Host Utilization Summary - trend chart showing what is the total compute % utilization of CPU and Memory over time of the projection period
- Storage Utilization Summary - trend chart showing what is the total storage % utilization of Amount, OverProvisioned and IOPS over time of the projection period
- Additional Resources - summarizes the changes in Virtual Machines, Hosts and Data Stores per period in the projection series. Note the changes are accumulative, and if one entity does not change, then the column will not display.
- Virtual Machines - shows a bar chart of the changes in the number of Virtual Machines per period in the projection series. Note the green bar represents the baseline of the initial / original count of the scope at the start of the projection series.
- Physical Machines - shows a bar chart of the changes in the number of Physical Machines / Hosts per period in the projection series. Note the green bar represents the baseline of the initial / original count of the scope at the start of the projection series.
- Datastores - shows a bar chart of the changes in the number of Storage in Data Stores per period in the projection series. Note the green bar represents the baseline of the initial / original count of the scope at the start of the projection series.
Projection Based Enhancements: The configuration of a plan includes many of the same modifications that you can make in any plan just with a better workflow to guide you through the set up with the following notable differences:
Time Periods: Now you can select how far out you want to run a projection (up to 5 years), and then also select the frequency to display results (frequency will be available in evenly distributed periods):
Baseline: We have incorporated 2 important options
1. leveraging the new 5.1 feature of being able to select a High Demand Period, where Ops Manager will automatically store the top 3 highest demand periods, values computed by the price of the demand, continuously analyzed, and stored for the top 3 for as long as the Ops Manager Control Server is managing the environment
2. Apply a workload utilization factor that increases the demand for the entire scope by a single factor of % utilization increase
Modify Demand and Supply: These have stayed the same with one important factor: you can now define WHEN and at what frequency you want these changes to take place.
Also you have options to Include Reserved VMs that you have defined in the Deploy tab:
Note for v5.1 the "Add VM(s) based on previous month" has been disabled to be introduced into a future release.
Default Settings for Quick Answers to Common Questions: Not sure what kind of scenario to run to get familiar with this new method of planning for the future? Why not take the defaults?
1. Scope = full scope (Note if you have a large environment, scope to a single cluster to get a faster response of results)
2. Time Periods = 3 months out from this month, and results will be seen monthly
3. Baseline = current snapshot
4. Demand = current demand and includes all reservations for the scope
5. Advanced = the settings below
