devices. Adding your power delivery devices to the appliance enables power management using
thermal limits, rated capacity, and derated capacity.
The Power Delivery Devices screen describes the following classes of devices:
•
HP Intelligent Power Distribution Units (HP iPDUs), which the appliance can automatically
discover and control.
•
Other power delivery devices that the appliance cannot discover. By manually adding these
devices to the appliance, they become available for tracking, inventory, and power
management purposes.
Regardless of how power delivery devices are added to the appliance, the appliance automatically
generates the same types of analysis (capacity, redundancy, and configuration). For iPDUs, the
appliance gathers statistical data and reports errors.
Connectivity and synchronization with the appliance
The appliance monitors the connectivity status of iPDUs. If the appliance loses connectivity with an
iPDU, an alert displays until connectivity is restored. The appliance will try to resolve connectivity
issues and clear the alert automatically, but if it cannot, you must resolve the issue and manually
refresh the iPDU to bring it in synchronization with the appliance.
The appliance also monitors iPDU to remain synchronized with changes to hardware and power
connections. However, some changes to devices made outside of the control of the appliance (from
iLO or the OA, for example) may cause them to become out of synchronization with the appliance.
You may have to manually refresh devices that lose synchronization with the appliance.
NOTE: HP recommends that you do not use iLO or the OA to make changes to a device. Making
changes to a device from its iLO or OA could cause it to lose synchronization with the appliance.
You can manually refresh the connection between the appliance and an iPDU from the Power
Delivery Devices screen. See the online help for the Power Delivery Devices screen to learn more.
22.2 Managing your data center
In the appliance, a data center represents a physically contiguous area in which racks containing
IT equipment—such as servers, enclosures, and devices—are located. The data center describes
a portion of a computer room and provides a useful grouping to summarize your environment and
its power and thermal requirements.
