Cloud Cruiser became HPE Consumption Analytics on Nov. 1, 2018. You'll still see the old name in places while we update this site.

Capacity planning

The Capacity Planning page shows both actual and forecast usage over a period of time, to facilitate capacity planning. You can filter the data shown in this section in a number of preset ways. It is presented in both charts and tabular format.

Here is a sample Capacity Planning page:


Capacity Planning shows consumption trends for actual usage and forecast data over a period of time, based on the forecast filters.

The charts and tables will show the following data:

  • Installed Capacity – Total capacity installed at the customer site; this is often the Requested Capacity plus a 10% buffer.
  • Requested Capacity – Contractual value indicating the amount of capacity requested by the customer.
  • Committed Capacity – Contractual value indicating the capacity that the customer will be billed for if the actual usage falls below this amount.
  • Actual Usage The capacity that is actually being used by the customer. 
  • Forecast Usage – The forecast capacity based on the actual usage.

Setting Filters

The Capacity Planning data is shown by service, and can be grouped by several preset filters. You can also change the time periods for showing the actual and forecasted data.

Filter data by service

You can switch between services by selecting the service to view from the Service selecting field:


Group by preset options

You can group the data by several preset methods. Some of the group by fields are dependent on the customer’s Report By option.

By default, the Capacity Planning page shows all data for the service in a single chart and table (this is the Group by option None). You can select different ways to group the data by selecting an option from the Group by filter:



Here is what the different Group by options mean:

  • None – show all data for the service in a single chart and table
  • Tier – show the data for each tier in a separate section (tiers are configured on the Service Options page)
  • Location – optional grouping option to show data by location for customers that report by Location or by Tier & Location
  • Device ID – show the data at the resource level, such as at the array level for 3PAR
  • Location and Tier – show the data at a tier level for each location 
  • When changing the Group by field, the data for the first group will be shown, with the rest of the groups collapsed. You can expand another group by clicking its header.


Working with actual and forecast data

You can modify the time periods for the actual and forecast data and type of forecasting by selecting the following filters:

  • Forecasting method
  • Base forecast on
  • Forecast period

Forecasting method allows you to select from three different algorithms for to forecast the data based on the historical actual usage:



Base forecast on allows you to select the number of months of historical actual usage data to show. The forecasting algorithms use this data to estimate the future usage based on historical trends. The charts and tables will change to show the number of months of historical data selected:



Forecast period allows you to select the number of months of forecasted data to show. The charts and tables will change to show the number of months of forecasted data selected:



Understanding charts

The charts shown for Capacity Planning show consumption trends for actual usage and forecast data over a period of time based on the forecast filters. The charts will show Installed Capacity and Actual/Forecast usage over a period of time, and colored bands may be shown based on contractual values (Requested and Committed Capacity).

These charts are interactive – you can hover over the chart and see these usage values for a specific day.

Interpreting chart bands

Depending on the Group by selection, the charts may show colored bands to indicate where the actual usage falls with regard to the contractual values Requested Capacity and Committed Capacity. Here is the coloring for these bands:



These bands are based on the following:

  • Critical – Range between Requested Capacity and Installed Capacity
  • Optimal – Range between Committed Capacity and Requested Capacity
  • Low – Range from 10% of Committed Capacity to Committed Capacity
  • Forgotten – Range from zero to 10% of Committed Capacity
    This could be an indicator that the ASM needs to take some action with the customer to try to move the usage toward the optimal band.
  • In the following chart, you can see that the actual and forecast usage fall into the Low band:


Viewing chart hover tooltips

As previously indicated, the charts are interactive. If you hover over the chart for a specific day, the contractual and usage data is shown in a tooltip.


Chart (Installed Capacity & Actual Usage)

In some cases, the Group by option does not have contractual values (Requested and Committed Capacity) associated with it. For example, if a customer has more than one 3PAR array but is charging for the usage based on tier, the customer will have Requested and Committed Capacity values when grouping by Tier but not when grouping by Device ID (Device ID is at the array level). In these cases, the charts will only show Installed Capacity and Actual Usage without the colored bands, since the bands are based on the contractual values.




Understanding Tables

The tables shown for Capacity Planning show consumption trends for actual and forecast usage data on a monthly basis, based on the forecast filters. Each column shows the Installed Capacity and Actual or Forecast usage for a month, and if the Group by option includes contractual values then it will also show Requested and Committed Capacity. The table will also show increases or decreases in Installed Capacity and Actual Usage in the cells to the left of the actual values (these will be colored green if the usage increases and red if the usage decreases).
