# Data Center screen details

If no resources are listed, you must add a resource. See Add a data center.

The following information appears on the Data Centers screen:

- A list of your data centers

- The general properties of the selected data center

- A 3D visualization of the racks in the data center

- The peak temperature of the racks and the devices in them

The appliance provides detailed health data, which you can use to determine the power and cooling capabilities of the devices in your data center. While the overall cooling in your data center may be sufficient, there may be areas that are insufficiently cooled due to factors such as poor airflow, concentration of excessive heat output, or wrap-around airflow at the ends of aisles.

You can investigate cooling issues using the 3D data center visualization, which uses color coding to display the peak temperatures of your racks. To do this, you must first enter the physical positions of the racks in your data center. You can then view the peak observed temperature in each area of your data center over the last 24 hours. If you have configured thermal limits for your racks, you can view any potential violations of these limits by hovering your pointer over a rack.

## General

Screen component | Description
--- | ---
Width x Depth | The width and depth of the data center, in meters or feet
Electrical derating | The electrical derating percentage for the data center
Default voltage | The default power line voltage for the data center
Power costs | The power cost per kilowatt hour (kWh) in the user-defined currency
Cooling capacity | The maximum cooling capacity of the data center, in kilowatts (KW)
Cooling multiplier | The ratio of cooling cost to power cost for the data center

## Layout

See Procedure: Changing the layout of a data center to learn more about changing the layout of a data center.

Data Center Layout

| A 3D visual representation of the physical layout of the data center and the racks within it. The color of a rack depicts the peak temperature of the device in the rack with the highest peak temperature in the last 24 hours. Click the front of a rack to view its contents. Hover your pointer over a device in the rack to view the device name, slot number, peak temperature over the last 24 hours, and when the peak temperature occurred. The device name is a hyperlink to its overview on the corresponding screen for the device type.
| A horizontal slider that zooms in (left) or out (right) on the data center visualization; visible when you hover your pointer over the Layout panel.
| A dial that rotates the data center view 360 degrees horizontally; visible when you hover your pointer over the Layout panel.
| A vertical slider that changes the data center view from a side view to a top-down view; visible when you hover your pointer over the Layout panel.
| A vertical color spectrum that represents a range of temperatures. These colors depict temperature data for devices in the data center. Hover your pointer over the bar to display the temperature that each color represents.

## Remote Support

Contacts are defined at the appliance level. Contacts can be edited and can be inherited by the enclosures belonging to a data center.

#### Contacts

Name | Name of contact
Type | Primary or secondary contact
Email | Email address of contact
Phone number | Phone number of contact

#### Address line 1

Address of contact

#### Address line 2

Optional address line

#### City

City of residence of the contact

#### State/Province

State/province of residence for the contact

#### Postal code

Postal code of contact

#### Country

Country of residence for the contact

#### Time zone

Defaults to the time zone set on the appliance

## Add or edit a data center

Screen component | Description
--- | ---
Name | A name to identify the data center.
Data type: | A maximum of 255 printable characters; no leading spaces
Width x Depth | The width and depth of the data center, in meters or feet.
Data type: | A maximum of 50 meters (164.042 feet); metric or US measurements, determined by the locale setting of your browser
Electrical derating | The percentage below the rated maximum power dissipation at which the devices are operated, accounting for case/body temperature, ambient temperature, and type of cooling. You can specify a derating percentage by selecting `Custom`, or you can choose not to apply derating to the rated maximum power dissipation by selecting `None`.
Default value: | `NA/JP` (20%) — North America/Japan
Default voltage | The default power line voltage for the data center.
Default value: | 220
Currency | The currency unit for energy costs.
Power costs | The energy cost per kWh, specified by the Currency.
Cooling capacity | The maximum cooling capacity for the data center, in KW. The appliance analyzes heat generation using this value.
Cooling multiplier | The ratio of cooling cost to power cost for the data center. This value represents the relative cost of cooling the system compared to the cost of powering the system. The default value of 1.5 indicates that it costs 1.5 times as much to cool the system as it does to power the system.
Data type: | Multiplier. This value is multiplied by the kWh consumed by the system to obtain the cooling kWh. The appliance uses this value for graphs that display power consumption.
Default value: | `1.5`
Data center grid | A visual representation of the physical dimensions of the data center. You can add racks to the grid from the Unpositioned Racks list by dragging them to the grid or by selecting them and clicking the Add button. See Procedure: Changing the layout of a data center to learn more.
Unpositioned Racks search box | The search box enables you to filter the Unpositioned Racks list.
Unpositioned racks list | This list displays the racks that have not yet been positioned in a data center.
Buttons | See Standard UI buttons for information about how buttons operate.
