• Idle power is the power consumption when server is idle

• Power capacity is the maximum of (2 * idle power, observed maximum power).

The following formulae is used used in calculating the underutilization value of a server,

Servers with an average utilization of less than or equal to <X>

, where <X> represents a utilization percentage. The range is between 80% to 20%, by default the value is

set to 15.

Servers with <Y> percentile utilization being less than or equal to <X>.

, where <Y> is the percentile. The range is between 0% to 20%, by default the value is set to 95.

Configuring underutilized servers settings

OMPC allows you to view the underutilized servers based on the power consumption.

1. In the left pane, click Analysis → Underutilized Servers and then click .

2. Enter a value in Power Utilization (X) text box and Percentile Utilization (Y) text box.

NOTE: The range for Power Utilization is 0–20. By default, the value is set to 15.

NOTE: The range for Percentile Utilization is 80–100. By default, the value is set to 95.

3. Click Save.

Power Analysis

OMPC helps you in monitoring and managing power in a data center. The observed monitoring data is

helpful in planning capacity expansion, placement suggestions.

In the left pane, click Analysis → Power Analysis. The Power Analysis screen is displayed. On this screen,

you can:

• Perform data center capacity expansion planning

• Analyze and view the placement suggestions

• Analyze and view power and space gains from underutilized servers

Analyzing capacity expansion

1. In the left pane, click Analysis and then click Power Analysis.

The Power & Space Analysis page is displayed.

2. In the Capacity Planning section, click launch.

Capacity Planning window is displayed.

3. From the Group Selection tab, select the data centers by clicking + to analyze the availability of

power and space. Click Next.

4. In the Model Selection tab, the servers models are displayed in Server Model Selection section.

Select the required server model for analysis.

The power and space calculations before and after allocation are displayed in the Resource

Availability section.

5. Click Next.

In the Capacity Allocation section, the analysis result is displayed.
