Chapter 3 Overview
This is done by managing and monitoring the hardware for a power event. The UPM software
can take action in one of the following ways:
Initiate a virtual machine migration if a host server experiences a power event
•
Initiate a Virtual Machine (VM) suspension or shutdown of VM of less priority while
•
keeping more critical VMs live
Gracefully shut down all VMs and its host server to keep more critical host/VM servers
•
live
Set user defined power budget as part of a disaster avoidance plan to guarantee a
minimum amount of battery run time during a power outage. The power budget is
maintained by using the load-shedding capabilities discussed above. It does not affect
system performance by reducing processor frequency. Power capping only maintains
system load by managing load shedding capabilities.
The UPM will read environmental (temperature over the limit) or UPS power alarms
(utility power loss) and will work with VMware's Site Recovery Manager (SRM) to
initiate a disaster recovery plan to initiate a move of critical applications to a back-up
data centre location or disaster recovery (DR) site.
Differences between UPP and UPM
Attention! The UPP and UPM software can not be installed on the same server at the same time.
Doing so will lead to unpredicted operation of either software or the UPS unit. In such a
situation support can not be provided and one of the applications has to be uninstalled.
The UPP software can only be used as a stand-alone software on a single host. The UPM
software can be used to manage multiple hosts. The UPM software also has additional
features. See the following Lenovo Press articles for further information:
