Business user policies

Turbonomic ships with default automation policies that are believed to give you the best results based on our analysis. For certain entities in your environment, you can create automation policies as a way to override the defaults.

Image target utilization

Turbonomic tracks utilization of desktop image resources for the business users in your Virtual Desktop Infrastructure (VDI) environment.

Attribute

Default Value

Image CPU Target Utilization

70

The target utilization as a percentage of CPU capacity.

Image MEM Target Utilization

70

The target utilization as a percentage of memory capacity.

Image Storage Target Utilization

70

The target utilization as a percentage of storage capacity.

Aggressiveness and observation period

Turbonomic uses these settings to calculate utilization percentiles. It then recommends actions to improve utilization based on the observed values for a given time period.

  • Aggressiveness

    Attribute

    Default Value

    Aggressiveness

    95th Percentile

    When evaluating utilization of compute and storage resources, Turbonomic considers a given utilization percentile. For example, assume a 95th percentile. The maximum utilization would be the highest value that 95% of the observed samples fall below.

    Using a percentile, Turbonomic can recommend more relevant actions, so that analysis can better exploit elasticity in your environment. A percentile evaluates the sustained resource utilization, and ignores bursts that occurred for a small portion of the samples. You can think of this as aggressiveness of resizing, as follows:

    • 100th Percentile – The least aggressive, recommended for critical workloads that need maximum guaranteed performance at all times.

    • 95th Percentile (Default) – The recommended setting to achieve maximum performance and savings.

    • 90th Percentile – The most aggressive, recommended for non-production workloads that can stand higher resource utilization.

  • Max Observation Period

    Attribute

    Default Value

    Max Observation Period

    Last 30 Days

    To refine the calculation of resource utilization, you can set the sample time to consider. Turbonomic uses historical data from up to the number of days that you specify as a sample period. (If the database has fewer days' data then it uses all of the stored historical data.)

    A shorter period means there are fewer data points to account for when Turbonomic calculates utilization percentiles. This results in more dynamic, elastic moves to different Desktop Pools, while a longer period results in more stable or less elastic moves. You can make the following settings:

    • Less Elastic – Last 90 Days

    • (Recommended) More Elastic – Last 30 Days

    • Most Elastic – Last 7 Days
