Configuring SHO > Defining Reference VMs and Hosts

Defining Reference VMs and Hosts

You can define the reference VMs on this tab. Reference VMs are used to calculate the remaining capacity of the Groups in terms of VMs. Custom VMs are used to normalize the CPU speeds whenever the normalization option is selected on the scenario planning page.

Reference VM Sizes

To define the reference VM size use one of the reference VM types provided in the Reference VM drop-down list. Based on the value selected in the Reference VM list, SHO considers the reference VM size to calculate the remaining capacity.

Note: The values defined for the reference VM size must be greater than 0.

The available VM levels are described in the following table:

Field Description
Data Center If you select Data Center as the reference VM type, SHO uses the average CPU, memory, and vDisk size of all the VMs available in the Data Center to calculate the reference VM size.
Custom

If you select Custom as the reference VM type, define the following values in the Custom row :

  • CPU size (in gigahertz) in the CPU (GHz) field.
  • Memory size (in gigabytes) in Memory (GB) field.
  • vDisk size (in gigabytes) in vDisk (GB) field.

SHO uses these values to calculate the reference VM size.

Small

If you select Small as the reference VM type, define the following values in the Small row :

  • CPU size (in gigahertz) in the CPU (GHz) field.
  • Memory size (in gigabytes) in Memory (GB) field.
  • vDisk size (in gigabytes) in vDisk (GB) field.

SHO uses these values to calculate the reference VM size.

Medium

If you select Medium as the reference VM type, define the following values in the Medium row :

  • CPU size (in gigahertz) in the CPU (GHz) field.
  • Memory size (in gigabytes) in Memory (GB) field.
  • vDisk size (in gigabytes) in vDisk (GB) field.

SHO uses these values to calculate the reference VM size.

Large

If you select Large as the reference VM type, define the following values in the Large row :

  • CPU size (in gigahertz) in the CPU (GHz) field.
  • Memory size (in gigabytes) in Memory (GB) field.
  • vDisk size (in gigabytes) in vDisk (GB) field.

SHO uses these values to calculate the reference VM size.

Weighted Average of S/M/L

If you select Wtd. Avg. of S/M/L as the reference VM type, define the CPU size (in gigahertz), memory size (in gigabytes), and vDisk size (in gigabytes) in the following rows:

  • Small
  • Medium
  • Large

SHO calculates the reference VM size using the weighted average of the small, medium, and large VMs deployed in the Data Center.

Reference Host for CPU Normalization

You can define the default configuration for reference hosts in this section. The configurations defined in this section are used for the custom hosts defined in the Optimization scenarios.

Optimization Opportunity

From the Analysis Based on drop-down list, select whether you want the Optimization Opportunity ratings to be calculated based on the utilization data or the configured capacity of the resources.

Shift

Select the shift for which you want SHO to view the data on the SHO Users' Interface.

SHO enables you to create different time shifts in the overall analysis period. You can create these shifts using the Administration Console. For more information, see Managing time shifts in the Online Help for Administrators.
