Using baseline analysis, Capacity Planner provides automatic recommendations for improvements in the configuration of machines currently active in your IT estate. This includes right-sizing recommendations, target vCPU configurations, hardware deployment in clusters, and storage reduction. The recommendations are fully configurable allowing you to set up activity threshold settings and minimum configuration for right-sizing.
In the Recommend panel, you can:
- View default recommendations for server activity and storage.
- Check estimated costs of cloud migration.
- View the list of hosts and workloads that are breaching thresholds.
In the Default Recommendations tab of the panel, you can find the server activity and storage recommendations for machines that are idle, underprovisioned or overprovisioned. When you change the sunburst view, recommendations are dynamically updated to display information relevant to your current view.
To see the full list of recommendations, click More. This displays the list of all machines with detailed recommendation on how to adjust the following:
- CPU and memory for servers.
- Demand and free space for storage.
To filter your view further, you can use the Grouping columns to provide more information about the machines. For more information on how to use groupings, see Groupings manager.
All recommendations are based on the way activity and right-sizing rules are configured. For more information, see Configure recommendations.
To configure activity and right-sizing rules for the recommendations, click Options in the Default Recommendations tab, and select the required option.
Note: Recommendations are only based on machines that are currently active. If a machine is switched off, it is not taken into consideration in the recommendations.
You can configure activity rules based on which recommendations will be made. Server activity is defined by the activity property which is the value of activity grouping. For more information, see Activity grouping.
When you change your configuration, the recommendations are automatically updated. Any machine that falls out of the norm, will have a recommendation:
- Idle — machines that meet these criteria are listed as idle and are recommended to be switched off.
- Low — machines that meet these criteria are listed as overprovisioned and are recommended to be right-sized.
- High — machines that meet these criteria are listed as underprovisioned and are recommended to be right-sized.
- All other machines are considered normal.
You can restore these settings at any point by clicking Reset.
You can set rules based on which right-sizing will be recommended. The configuration is the same as for the right-sizing operations, for more information see Right-sizing.
In the Cloud migration tab, you can check the estimated cost of migrating your virtual machines into one of the cloud providers. Currently, only Amazon Web Services (AWS) is available.
Capacity Planner looks at all the active machines that are currently visible in your sunburst view and determines the closest and cheapest match for each virtual machine. It automatically suggests cloud instance configurations in AWS, scoped to a baseline view, taking optimal capacity configuration into consideration in order to reduce costs effectively. The pricing details are pulled directly from the cloud provider.
The following migration options are available:
- Like for like — estimated costs of migration if you do not follow the right-sizing recommendations.
- Rightsized — estimated costs of migration if right-sizing recommendations are followed.
Depending on your use case, you can change the recommendation rules. To do this, click Options and Configure.
You can select AWS specific settings such as region (each region has different pricing), instance family that Amazon Web Services provides or network performance. For more information on these settings and how they can affect your system setup, please refer to AWS official documentation.
