22.2.3 About data centers
A data center represents a physically contiguous area in which racks containing IT equipment are
located.
For example, you have IT equipment in two rooms or on separate floors. You could create a data
center for each of these areas.
Each server, enclosure, or power distribution device in your data center can report its power
requirements, but it can be difficult to understand the power and cooling requirements for your
data center as a whole. The appliance enables you to bring power and cooling management of
your servers, enclosures, and power delivery devices together in a single management system.
The Layout view of the data center is color-coded to depict the peak temperature recorded in the
last 24 hours.
Default data center: Datacenter 1
When you initialize the appliance for the first time, it creates a data center named Datacenter
1
. The appliance provides this data center as a place to visualize your racks. You can rename or
edit this data center to match the values and layout of your data center, you can use it as the basis
for a planned data center model, or you can delete this data center without adverse effects.
Default rack placement
When you add a rack to the appliance for management, the appliance displays the rack in all
data centers even though its actual location is not known. If you view a data center that displays
unpositioned racks, a warning appears to alert you that unpositioned racks are being displayed.
When you assign a rack to a data center, it is no longer displayed in other data centers.
22.3 Managing racks
Racks allow you to manage temperature, power, and depict the layout of enclosures.

22.3.3 About racks
A rack is a physical structure that contains IT equipment such as enclosures, servers, power delivery
devices, and unmanaged devices (an unmanaged device uses slots in the rack and consumes
power or exhausts heat, but it is not managed by the appliance). You can manage your racks and
the equipment in them by adding them to the appliance. Having your racks managed by the
appliance enables you to use the appliance for space and power planning. The appliance also
gathers statistical data and monitors the power and temperature of the racks it manages.
